Brief summary:
Knee osteoarthritis (OA) causes patients considerable joint pain and leads to instability, reduced range of motion, and functional limitations. Current treatment limitations have generated interest in alternative options to restore function and alleviate joint pain, some with the aim of healing damaged articular cartilage. There has been preliminary support in the literature for reduced pain and improved functional performance in patients who receive mesenchymal stem cells (MSCs) as part of a treatment regimen. MSCs can be costly and are limited by complex regulatory issues. This interest in an alternative isolation method lead to the development of Lipogems. Lipogems is a technique to harvest, process, and inject minimally manipulated adipose tissue. This procedure is enzyme free and requires no clonal expansion or manipulation. The goal of this study is to evaluate the possible benefits of reduced joint pain and increased joint functionality in patients with knee osteoarthritis after the injection of Lipogems. In addition, given the limitations of prior research on the efficacy of intra-articular corticosteroids, the investigators will also include this as an additional study group to compare to placebo. There have been case reports published showing favorable outcomes. This would be the first study reporting data on the efficacy of Lipogems for pain relief in knee OA in a randomized, controlled clinical trial with a larger sample of patients.

The investigators hypothesize that patients who receive an injection of Lipogems will experience a decrease in pain of the affected knee and an increase in joint functionality in comparison to placebo. The investigators also hypothesize that patients who receive an intra-articular corticosteroid will experience decreased pain or improved functionality in the affected joint compared to placebo.

Detailed description:
Objectives:

1. The purpose of this study is to evaluate the possible benefits of reduced joint pain and increased joint functionality in patients with knee osteoarthritis after the injection of Lipogems. Based on limitations of prior research, intra-articular corticosteroids are included as a study group to be evaluated for impact on pain relief and joint functionality in comparison to placebo.
2. The investigators hypothesize that patients who receive an injection of Lipogems will experience a decrease in pain of the affected knee and an increase in joint functionality in comparison to placebo. The investigators also hypothesize that patients who receive an intra-articular corticosteroid will experience decreased pain or improved functionality in the affected joint.

Background:

Osteoarthritis (OA) causes patients considerable joint pain and leads to instability, reduced range of motion, and functional limitations. Pathologic findings of OA include decreased articular cartilage, joint space narrowing, osteophytes, subchondral sclerosis and bone cysts. Currently, treatment options are confined to symptom management only. Options for treatment include: topical preparations, nonsteroidal anti-inflammatory drugs (NSAIDs), intra-articular injections, and, in severe cases, total knee arthroplasty. Review of recent recommendations shows limitations to all available treatments. Oral NSAIDs have shown relief, but is limited to patients without risk factors or contraindications. Topical NSAIDs are recommended in elderly patients or those with GI risk factors, rather than oral NSAIDs. However, pain improvement took 12 weeks and was not long-lived, potentially due to compliance issues in application. A recent systematic review of intra-articular corticosteroids reported that, due to low-quality evidence, it is inconclusive whether intra-articular corticosteroids provided any short or long-term pain relief. Taylor's review of hyaluronic acid treatment is hampered by the variability of preparations currently on the market and shortage of double-blind placebo controlled studies, but conflicting data is reported. Osteoarthritis Research Society International currently recommends corticosteroid injections for short-term pain relief only, and is inconclusive in recommending hyaluronic acid.

The aforementioned treatment limitations have generated interest in alternative options to restore function and alleviate joint pain, some with the aim of healing damaged articular cartilage. It is well known that articular cartilage is avascular and lacks innervation, which limits its intrinsic healing and repair capabilities. Chondrocytes, derived from MSCs, have limited potential to replicate, which also limits the intrinsic healing and repair capabilities of articular cartilage. The stromal vascular fraction, containing adipose derived mesenchymal stem cells (MSCs), has historically been isolated successfully via enzymatic processes. There has been preliminary support in the literature for reduced pain and improved functional performance in patients who received MSCs as part of treatment. However, approaches to isolate MSCs are costly, time consuming, require extensive lab equipment, and are currently limited by complex regulatory issues.

Thus, interest in an alternative isolation method lead to the development of Lipogems. Lipogems is a technique to harvest, process, and inject minimally manipulated adipose tissue. This procedure is enzyme free and requires no clonal expansion or manipulation. Lipoaspirate is harvested and washed in saline solution, then processed through a closed-system device that micro-fragments the adipose tissue. This mechanical process retains the vascular architecture, mature pericytes, and MSCs for autologous injection.

As new technologies are becoming available for the treatment of OA, it is important that investigators gather high-quality data on their efficacy and outcomes. The goal of this study is to evaluate the possible benefits of reduced joint pain and increased joint functionality in patients with knee osteoarthritis after the injection of Lipogems. In addition, given the limitations of prior research on the efficacy of intra-articular corticosteroids, the investigators will also include this as an additional study group to compare to placebo. Although Lipogems is relatively new to the United States, it has been used for a variety of orthopaedic arthroscopic applications overseas including the treatment of knee OA and is being used more frequently now in the United States. As of now, there are no published studies reporting the outcomes of patients who receive Lipogems for knee OA. There have been case reports published showing favorable outcomes. Thus, this would be the first study reporting data on the efficacy of Lipogems for pain relief in knee OA in a randomized, controlled clinical trial with a larger sample of patients. It would also be the only study to date comparing Lipogems to intra-articular corticosteroids and placebo injections. The investigators feel this study design will provide new insight into the efficacy of Lipogems for pain relief of symptomatic knee OA as well as offer new data on the efficacy of intra-articular corticosteroids in this application.

Arms:
arm 1: Patients who are randomized to the placebo group will receive an injection of 7cc of sterile saline in the affected knee. arm 2: Patients who are randomized to the corticosteroid group will receive an injection of 2cc (80mg) of triamcinalone acetonide injectable suspension mixed with 5 cc of 1% plain lidocaine for a total of 7cc of fluid injected in the affected knee. arm 3: Patients who are randomized to the Lipogems treatment group will undergo a lipoaspiration from their abdomen and autologous injection of the harvested adipocytes into their knee. It is standard to harvest three to four times more adipose tissue than is planned to be injected to account for tissue processing by the Lipogems device. The investigators plan to inject 7cc of autologous adipose tissue. Thus, the investigators will harvest between 25 and 30 cc of adipose tissue from each patient. The tissue will be processed immediately and 7cc will be injected. Any remaining adipose tissue will be disposed of immediately in biohazardous waste.

Interventions: intervention 1: Microfragmented Adipose Tissue (Lipogems) intervention 2: Corticosteroid injection intervention 3: Saline
Intervention descriptions: intervention 1: Lipogems is a technique to harvest, process, and inject minimally manipulated adipose tissue. This procedure is enzyme free and requires no clonal expansion or manipulation. Lipoaspirate is harvested most commonly from the abdomen and washed in saline solution, then processed through a closed-system device that micro-fragments the adipose tissue. This mechanical process retains the vascular architecture, mature pericytes, and MSCs for autologous injection. Lipogems is currently FDA-approved for orthopedic and arthroscopic procedures; thus, this would be an on-label use for knee injections. intervention 2: Cortisone is a standard of care injection to reduce joint inflammation. intervention 3: Sterile saline injection will act as a placebo group.

1. Objectives
1.1. The purpose of this study is to evaluate the possible benefits of reduced 
joint pain and increased joint functionality in participants with knee 
osteoarthritis after the injection of Lipogems. Based on limitations of 
prior research, intra-articular corticosteroids are included as a study 
group to be evaluated for impact on pain relief and joint functionality in 
comparison to placebo.
1.2. We hypothesize that participants who receive an injection of Lipogems will 
experience a decrease in pain of the affected knee and an increase in joint 
functionality in comparison to placebo. We also hypothesize that participants 
who receive an intra-articular corticosteroid will experience decreased pain or 
improved functionality in the affected joint.
2. Background
2.1. Osteoarthritis (OA) causes patients considerable joint pain and leads to 
instability, reduced range of motion, and functional limitations. Pathologic 
findings of OA include decreased articular cartilage, joint space narrowing, 
osteophytes, subchondral sclerosis and bone cysts.1 Currently, treatment options 
are confined to symptom management only. Options for treatment include: 
topical preparations, nonsteroidal anti-inflammatory drugs (NSAIDs), intra-
articular injections, and, in severe cases, total knee arthroplasty. Review of 
recent recommendations shows limitations to all available treatments. Oral 
NSAIDs have shown relief, but is limited to patients without risk factors or 
contraindications. Topical NSAIDs are recommended in elderly patients or those 
with GI risk factors, rather than oral NSAIDs. However, pain improvement took 
12 weeks and was not long-lived, potentially due to compliance issues in 
application.2,3 A recent systematic review of intra-articular corticosteroids 
reported that, due to low-quality evidence, it is inconclusive whether intra-
articular corticosteroids provided any short or long-term pain relief.4 Taylor’s 
review of hyaluronic acid treatment is hampered by the variability of 
preparations currently on the market and shortage of double-blind placebo 
controlled studies, but conflicting data is reported.3 Osteoarthritis Research 
Society International currently recommends corticosteroid injections for short-
term pain relief only, and is inconclusive in recommending hyaluronic acid.5 
The aforementioned treatment limitations have generated interest in alternative

articular cartilage.6,7 The stromal vascular fraction, containing adipose derived 
mesenchymal stem cells (MSCs), has historically been isolated successfully via

reduced pain and improved functional performance in patients who received 
MSCs as part of treatment.7,9,10 However, approaches to isolate MSCs are costly, 
time consuming, require extensive lab equipment, and are currently limited by 
complex regulatory issues.11-13
Thus, interest in an alternative isolation method lead to the development of 
Lipogems. Lipogems is a technique to harvest, process, and inject minimally 
manipulated adipose tissue. This procedure is enzyme free and requires no 
clonal expansion or manipulation. Lipoaspirate is harvested and washed in 
saline solution, then processed through a closed-system device that micro-
fragments the adipose tissue. This mechanical process retains the vascular 
architecture, mature pericytes, and MSCs for autologous injection.12,13
As new technologies are becoming available for the treatment of OA, it is 
important that we gather high-quality data on their efficacy and outcomes. The 
goal of this study is to evaluate the possible benefits of reduced joint pain and 
increased joint functionality in participants with knee osteoarthritis after the 
injection of Lipogems. In addition, given the limitations of prior research on 
the efficacy of intra-articular corticosteroids, we will also include this as an 
additional study group to compare to placebo. Although Lipogems is relatively 
new to the United States, it has been used for a variety of orthopaedic 
arthroscopic applications overseas including the treatment of knee OA and is 
being used more frequently now in the United States. As of now, there are no 
published studies reporting the outcomes of patients who receive Lipogems for 
knee OA. There have been case reports published showing favorable outcomes. 
Thus, this would be the first study reporting data on the efficacy of Lipogems 
for pain relief in knee OA in a randomized, controlled clinical trial with a larger 
sample of participants. It would also be the only study to date comparing 
Lipogems to intra-articular corticosteroids and placebo injections. We feel this 
study design will provide new insight into the efficacy of Lipogems for pain 
relief of symptomatic knee OA as well as offer new data on the efficacy of intra-
articular corticosteroids in this application. 
2.2. We do not have any preliminary data. There is, at this point, no study published 
explicitly evaluating the efficacy of Lipogems in patients with knee osteoarthritis, 
although Lipogems has been used for this purpose and is acknowledged in case 
reports. One case study by Striano et al reports decreased knee pain and no 
adverse side effects following injection of Lipogems.14 
2.3. Estimates say that there are between 15-27 million US adults age 25 or older 
with clinical OA of at least one joint, and that 49.7% of people over the age of 65 
report that they have diagnosed arthritis.15-17 The lifetime risk of symptomatic 
knee osteoarthritis is estimated to be 13.8%, and an even higher risk is identified 
for obese persons (19.7%) and females (16.3%).18
OA is not exclusive to patients over 65. Recent estimates show that 
approximately 6.6 million people between the ages of 45-64 had OA in 2011-

and intra-articular corticosteroid injections for symptomatic knee osteoarthritis:

2012. Furthermore, it is estimated that 1.7 million adults under the age of 45 had 
OA in the same year. 17 Thus, the burden of OA is much more widespread than 
the elderly population.
Current therapies are limited to symptom management only, none curative or 
capable of stopping the progress of disease. Thus, a staggering number of 
Americans of all ages are living with a chronically painful joint condition. 
Furthermore, with the burden of an aging population and high rate of obesity in 
the United States, the management and treatment of OA will continue to be an 
important health concern.
As new technologies are becoming available for the treatment of OA, it is 
important that we gather high-quality data on their efficacy and outcomes. The 
goal of this study is to evaluate the possible benefits of reduced joint pain and 
increased joint functionality in participants with knee osteoarthritis after the 
injection of Lipogems. In addition, given the limitations of prior research on 
the efficacy of intra-articular corticosteroids, we will also include this as an 
additional study group to compare to placebo. This would be the first study to 
evaluate the efficacy of Lipogems for pain relief in knee OA in a randomized, 
controlled clinical trial with a large sample of participants. It would also be the 
only study to date comparing Lipogems to intra-articular corticosteroids and 
placebo injections. We feel this study design will provide new insight into the 
efficacy of Lipogems for pain relief of symptomatic knee OA as well as offer 
new data on the efficacy of intra-articular corticosteroids for this application. .
3. Study Design
3.1. This study will be conducted as a randomized, placebo-controlled clinical trial. 
Participants will be randomized to receive either Lipogems, intra-articular 
corticosteroids, or a placebo injection of saline. Lipogems is cleared for use by 
the FDA in orthopaedics and arthroscopy and is offered as a treatment option for 
knee osteoarthritis. This study will be evaluating the effectiveness (not safety) of 
Lipogems when compared to corticosteroids and placebo. Thus, no information 
will be submitted to the FDA.
3.2. It is not feasible to blind participants who are randomized to receive Lipogems, 
as adipose tissue must be obtained from the participant. However, participants 
randomized to receive intra-articular corticosteroids or placebo injections will 
be blinded. 
3.3. Randomization will be stratified according to baseline pain severity as defined 
here, ethnicity, and age to ensure a balanced assignment across the three groups 
with respect to important determinants. Stratification will not be based on 
radiographic severity as previous studies have shown no correlation between the 
radiographic severity of knee osteoarthritis and the pain experienced by the 
patient.
4. Inclusion and Exclusion Criteria


PROTOCOL TITLE: “Evaluating the efficacy of micro-fragmented adipose tissue 
and intra-articular corticosteroid injections for symptomatic knee osteoarthritis: 
a randomized, placebo controlled study”
Page 6 of 40
Version Date: March 29, 2018
4.1. Participants will be recruited from the patient population at the clinics of Dustin 
Richter, MD, Robert Schenck, MD, Andrew Veitch, MD and Suki Pierce, PA-C at 
the University of New Mexico’s Orthopaedic Department. Since all potential 
participants will be independently seeking care for osteoarthritis, the 
participating clinicians and research staff will screen the patients for inclusion 
criteria during their standard examination. Qualifying patients will be offered 
enrollment into the study at that time.  
4.2. Inclusion criteria include being the age of eighteen or older, diagnosed 
symptomatic knee osteoarthritis, and radiographic evidence of knee 
osteoarthritis. For the purposes of this study, radiographic evidence of knee 
osteoarthritis is defined at any one or more of the following: osteophytes, joint 
space narrowing, loss of articular cartilage thickness, subchondral sclerosis or 
cysts. Patients will also meet inclusion criteria if their intake sheet pain score is 
at least a 3 out of 10, as pain scores less than 3 are unlikely to show a clinically 
meaningful improvement from any treatment option. Patients will be excluded 
from the study if they have a history of treatment with any intra-articular knee 
injection or have current ligament instability as demonstrated by a positive 
Lachman Test, Anterior or Posterior Drawer Test, or positive Valgus or Varus 
Stress Test. 19 Patients with a known allergy to lidocaine will also be excluded 
from the study. Patients will be excluded if they do not meet our above-mentioned 
severity criteria with a pain score of at least 3 on the intake sheet.
4.3. This study will only include English or Spanish speaking adults over the age of 
eighteen who are capable of independently consenting to participate in a 
research study. This study will not include any children, pregnant women, or 
prisoners. Women of childbearing age will be included only after they have had a 
negative urine pregnancy test at point of care.
4.4. Individuals under the age of 18 will be excluded from this study. As osteoarthritis 
is largely considered a degenerative joint disease, this population is highly 
unlikely to have osteoarthritis of the knee and thus will not be eligible for the 
study. 
5. Number of Subjects
5.1. This study will take place solely at the University of New Mexico Hospital. 
5.2. Based on our power analysis, we need 75 participants to complete the study. All 
subjects will have been pre-screened for eligibility by the participating 
clinicians. 
5.3. We will take advantage of the 5-repeated measurements of joint pain and 
functionality from each patient, and compare the post-treatment trajectory of 
joint pain and functionality over follow-up between a pair of treatment groups. 
This approach facilitates group comparisons (1) at individual follow-up times, 
(2) life course of effects over the entire follow-up period. This will be done by 
means of mixed-effects regression models which incorporate both within-patient

(over time) and between-patient variations, and are more flexible in making 
inference on group differences. The method also allows for the inclusion of 
multiple covariates (see below) in the model to quantify effects attributable to the 
treatments. We will also consider repeated measurement analysis of covariance 
and pairwise comparison (e.g. t-tests) to validate our analysis with respect to 
robustness and sensitivity. We will follow LaPrade’s recent recommendations of 
minimal reporting requirements for treatments that potentially include 
mesenchymal stem cells, such as Lipogems. This includes age, gender, diabetes 
status, inflammatory conditions, pre-existing joint problems, and current NSAID 
use.19 Since patient perception of post-treatment pain as measured by the VAS 
scale is a main variable of interest in our hypothesis, we searched the literature 
for previous studies in which the variability of pain using a VAS scale was 
investigated.20-23 We estimated that the standard deviation likely to be found for 
our own observations will be approximately 35 on a 100 point scale, 
conservatively. We assume that most clinicians will consider a difference in post-
treatment pain of about 15 points to be clinically important, as supported by 
Tashjian et al, who estimated 1.4 cm as the minimal clinically important 
difference on a 10 cm scale. To determine an adequate sample size for our pilot, 
we assumed average change in pain score over the follow-up to be 10-15, and 
standard deviation to be 10-20. To have 80% power with a 5% Type I error rate, 
an approximate 2-way ANOVA model suggest sample size in the range of 18-49 
per group. We adopt n=22 as our minimum sample size per group based on the 
assumption of 15-point change in pain score over time on average and a 20-point 
standard deviation over time. Within the recruitment time window, we will aim to 
enroll n=25 or more participants in each of the three treatment arms so long as 
the logistics permit. We expected the mixed-effect model will increase the power 
by utilizing the longitudinality of the data, compensating potential loss of power 
due to drop-outs and serial correlation. 
6. Study Timelines
6.1. Describe:

Individuals who agree to participate in this study will be enrolled during an 
initial screening visit which they will have independently sought and 
scheduled. Their participation will involve one procedure visit, two brief 
follow-up visits, and three online completion of surveys. We anticipate that it 
will take approximately 15 months from date of enrollment to complete each 
individual subject’s procedure and follow-up visits, allowing time for 
flexibility in scheduling based on the clinician and subject’s schedules. 

We estimate that it should take approximately three months to enroll 75 
subjects. We anticipate this being feasible based on the four participating 
clinicians’ current schedules. Roughly, an orthopaedic surgeon may see 
upwards of 50 patients a day. Approximately 10% of these patients have knee 
OA and potentially qualify for the study.

of these patients have pain as a result of osteoarthritis which has not been 
previously diagnosed. He pursues a conservative treatment algorithm with these 
individuals that consists of activity modification, weight loss, oral anti-
inflammatories, and intra-articular knee cortisone injections or hyaluronic acid 
injections prior to referring the patient to any of his colleagues for consideration 
of a reconstructive procedure (knee replacement). His research interests have 
included: Multi-ligamentous knee injuries, knee cartilage repair, and evidence-
based medicine with a focus on quality and value-added care. Specifically 
related to this proposal, he recently published a comprehensive review in Sports 
Health evaluating the efficacy of knee articular cartilage repair and restoration 
techniques. He has also studied and published on the psychosocial and 
demographic factors influencing pain scores of patients with knee osteoarthritis 
(UNMORJ 2016). Lastly, he also recently published on looking at the value in 
healthcare regarding inpatient versus outpatient partial knee replacements.
For this proposal, he will serve as the Principal Investigator and will be the 
primary contact for all correspondence related to the study.  He will be 
responsible for contributing to the overall design and conduct of the study.  He 
will oversee subject recruitment and follow-up for and will be responsible for 
supervision of the research support staff at the University of New Mexico. He 
will assure integrity and security of the data and will be responsible for timely 
completion of progress reports as well as preparation of abstracts and 
manuscripts to disseminate the results.  He will use his collective research and 
administrative experience to ensure that the study is completed within budget and 
in compliance with all federal and University of New Mexico regulations.

conducting this study, including their statistical department, rooms and 
facilities, and their study coordinators to help gather survey data.
10.Prior Approvals
10.1. We will be awaiting funding approval and IRB approval prior to conducting the 
research. We have already received departmental approval. 
10.2. Departmental Review Form.
10.3. Not applicable. No x-rays are required during participation in the study. 
Patients who qualify for the study will have obtained standard of care x-rays 
prior to enrollment in the study as part of their provider’s evaluation.
10.4. Drug attachment.
11.Multi-Site Research
11.1. Not applicable. This study will be conducted at the University of New Mexico 
Hospital and CTSC and will not include any other sites
11.2. Not applicable. This study will be conducted at the University of New Mexico 
Hospital and CTSC and will not include any other sites. 
11.3. Not applicable. The treatments used in this study are FDA approved and being 
used in the manner intended.
12.Study Procedures 
12.1. In chronological order, all research procedures and interventions being 
performed and when they are performed.
1. Participants will be screened prior to enrollment. Depending on their 
medical history and prior consultations, they will likely have a physical exam 
and x-rays of the affected knee(s). This is standard of care and will happen 
prior to enrollment in the study. X-ray images and medical data from these 
visits may be used for the purposes of analyzing statistical data.

and intra-articular corticosteroid injections for symptomatic knee osteoarthritis: 
a randomized, placebo controlled study”
Page 12 of 40
Version Date: March 29, 2018
2. Upon enrollment, participants will be randomized to a treatment group and 
scheduled for their injection procedure. 
3. At their injection visit, participants will complete the Western Ontario and 
McMaster Universities Osteoarthritis Index, a Visual Analog pain scale, and 
the Knee Injury and Osteoarthritis Outcome Score scales to establish a 
baseline. They will also fill out a medication log to document any medications 
that they take, including oral pain medications, although we will not be 
intervening with oral medications. They will complete these surveys and the log 
again at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year after the injections
4. Participants will receive their assigned injection. Participants who are 
randomized to the placebo group will receive an injection of 7cc of sterile 
saline. Participants who are randomized to the corticosteroid group will receive 
an injection of 2cc (80mg) of Kenalog-40 (triamcinalone acetonide injectable 
suspension, USP) mixed with and 5 cc of 1% plain lidocaine for a total of 7cc of 
fluid injected. Kenalog injections are part of the current standard of care for 
patients with osteoarthritis of the knee. Participants who are randomized to the 
Lipogems treatment group will undergo a lipoaspiration from their abdomen 
and autologous injection of the harvested adipocytes into their knee. It is 
standard to harvest three to four times more adipose tissue than is planned to be 
injected to account for tissue processing by the Lipogems device. We plan to 
inject 7cc of autologous adipose tissue. Thus, we will harvest between 25 and 
30 cc of adipose tissue from each patient. The tissue will be processed 
immediately and 7cc will be injected. Any remaining adipose tissue will be 
disposed of immediately in biohazardous waste.  Lipogems is currently 
approved for orthopedic and arthroscopic procedures; thus, this would be an 
on-label use. All injections will be performed in the clinic by Dr. Richter, Dr. 
Schenck, and Pierce PA-C as an in-office procedure.
5. Participants will be scheduled to return for in-person follow-up visits with a 
research staff member at 6 weeks and 6 months after their injection, where they 
will again complete a medication log, Western Ontario and McMaster 
Universities Osteoarthritis Index, a VAS pain scale, and the Knee Injury and 
Osteoarthritis Outcome Score scales. They will also complete the above surveys 
and log at 2 weeks, 3 months, and 1 year post injection, but these will be 
completed online. The above mentioned surveys and medication log will be 
generated in RedCap and emailed securely to participants for their completion. 
If participants do not have email or access to the internet, these surveys will be 
completed over the phone and entered into RedCap by research staff. 
6. Upon completion of their 1-year questionnaires, participants who were 
randomized to receive Lipogems or Corticosteroid injections will be finished 
participating in the study. 
7. Upon completion of their 1-year questionnaires, participants who were 
randomized to receive placebo injections will be offered the choice to cross-
over to the corticosteroid group. Whether they choose to have the injection or 
not, their participation in the study will be completed.

13.Data Analysis
13.1. We will take advantage of the 5-repeated measurements of joint pain and 
functionality from each patient, and compare the post-treatment trajectory of 
joint pain and functionality over follow-up between a pair of treatment groups. 
This approach facilitates group comparisons (1) at individual follow-up times, 
(2) life course of effects over the entire follow-up period. This will be done by 
means of mixed-effects regression models which incorporate both within-patient 
(over time) and between-patient variations, and are more flexible in making 
inference on group differences. The method also allow for the inclusion of 
multiple covariates (see below) in the model to quantify effects attributable to 
the treatments. We will also consider repeated measurement analysis of 
covariance and pairwise comparison (e.g. t-tests) to validate our analysis with 
respect to robustness and sensitivity.
13.2. Since patient perception of post-treatment pain as measured by the VAS scale is 
a main variable of interest in our hypothesis, we searched the literature for 
previous studies in which the variability of pain using a VAS scale was 
investigated.20-23 We estimated that the standard deviation likely to be found for 
our own observations will be approximately 35 on a 100 point scale, 
conservatively. We assume that most clinicians will consider a difference in 
post-treatment pain of about 15 points to be clinically important, as supported 
by Tashjian et al, who estimated 1.4 cm as the minimal clinically important 
difference on a 10 cm scale. To determine an adequate sample size for our pilot, 
we assumed average change in pain score over the follow-up to be 10-15, and 
standard deviation to be 10-20. To have 80% power with a 5% Type I error an 
approximate 2-way ANOVA model suggest sample size in the range of 18-49 
per group. We adopt n=22 as our minimum sample size per group based on the 
assumption of 15-point change in pain score over time on average and a 20-
point standard deviation over time.
14.Provisions to Monitor the Data to Ensure the Safety of Subjects
14.1. Corticosteroids are standard of care. Lipogems is approved for use in 
orthopaedics and arthroscopic procedures. Participants will be closely followed 
by the participating clinicians/investigators through the follow-up visits 
required for participation. All measures will be taken to ensure that participants 
receive appropriate care. 
14.2. Patients will be informed of the risks of participating prior to enrolling in the 
study and may choose to enroll or not enroll. They will be reminded of expected 
post-procedural findings and will be monitored for adverse reactions by the 
participating clinicians at their follow-up visits.
14.3. The data monitoring committee will consist of Dr. Dustin Richter, Dr. Daniel 
Wascher [Orthopaedic Sports Medicine], Dr. Gehron Treme [Orthopaedic

Sports Medicine]; this committee will conduct a preliminary review of the 
existing data once 10 participants have been enrolled in each group. 
14.4. The existing literature has been reviewed regarding Lipogems. A board 
certified plastic surgeon was consulted regarding adverse effects of 
lipoaspiration procedures and the adverse risks are detailed in this protocol 
and the consent form. 
14.5. N/A. Safety data is not collected in this study.
14.6. The research will be suspended and/or terminated if there is an unexpected 
serious adverse event that requires further investigation.
15.Withdrawal of Subjects
15.1. We do not anticipate any medical reasons to withdraw subjects from the study 
without their consent. If participants are not adherent and miss follow-up 
appointments, refuse to be scheduled, or do not respond to scheduling requests, 
they will be withdrawn from the study. 
15.2. Participants may withdraw at their request and continue to seek standard of 
care treatments with the physician of their choice. No labs/tapering of meds/or 
physical exams are necessary to withdraw.
15.3. Partial withdrawal will be permitted if a patient desires to continue 
participating in data collection but no longer wishes to be seen for follow-up. 
The questionnaires would be completed online only. All previously collected 
data will still be used for research purposes unless the patient explicitly asks for 
data to be excluded.
15.4. If a patient withdraws, all previously collected data will still be used for 
statistical analysis unless the participant explicitly asks for their previous data 
to be excluded from further consideration. Describe the disposition of existing 
data/specimens when a subject withdraws.
15.5. If a patient requests to be withdrawn, Dustin Richter, MD, the principal 
investigator, must be made aware. If the patient requested that their data be 
destroyed and not used for analysis, then the data will be properly destroyed. 
Otherwise, data that was collected prior to withdrawal from the study may be 
used for analysis.
16.Data Management/Confidentiality
16.1. Members of the research team will be permitted to access the participants’ 
medical records through PowerChart to confirm participant eligibility and 
document procedures and follow-up visits. PHI will be reviewed as part of the 
normal screening process in clinic.
16.2. Members of the research team will have access to direct identifiers only as 
necessary to confirm participant eligibility and document procedures and 
follow-up visits.

Version Date: March 29, 2018
16.3. The research team will have access to the patient’s PHI, as data may be needed 
from their consultation visits prior to enrollment in the study. Furthermore, they 
will have access to the medical record as procedures and follow-up visits will 
be documented in their medical records.
16.4. Not applicable. The study team may only know of any sensitive PHI if noted in 
medical chart. 
16.5. Not applicable. 
16.6. Participants will fill out questionnaire at their procedure and their 6 week and 
6 month visits. These questionnaires will be filled out on paper and will only 
have the participant’s unique identifier number on them. The data will be 
entered into RedCap by a member of the research staff. These paper copies will 
be kept in a locked file cabinet in Dustin Richter, MD’s office behind a locked 
door. In addition, each participant will be assigned a number from 001-100. 
This code will be kept on a password protected excel file on Dustin Richter, 
MD’s password protected computer located in his office behind a locked door. 
Only the PI and research staff will have access to any of these documents. No 
data is to be transported or transmitted to any other computer or location. 
Participants will also complete the questionnaires via RedCap (or phone if the 
patient doesn’t have email or internet access) at 2 weeks, 3 months, and 1 year 
post injection. If a patient has internet access and email, surveys will be sent 
and completed securely via RedCap. If performed by phone, the member of the 
research staff will collect the data on paper and it will then be transcribed into 
RedCap. 
Data will be kept for one year after full completion of data collection to allow 
time for data analysis and manuscript writing. Paper files, such as consent 
forms and questionnaires, will be appropriately shredded and disposed of. 
Excel files will be deleted. As no additional copies will be stored, this will 
destroy all of the identifiers and excel logs.
16.7. Each participant will be assigned a number from 001-100. This code will be 
kept on a password protected excel file on Dustin Richter, MD’s password 
protected computer located in his office behind a locked door. There will only 
be patient names and unique identification numbers on this document. Only the 
PI and research staff will have access to the document.
16.8. Not applicable. As participants will be answering questionnaires and filling 
them out on their own, there is no need for quality control.
16.9. Not applicable. Data will not be transferred or transmitted to outside locations 
or entities. Any paper copies of questionnaires will be collected within CTSC 
facilities and will be input into RedCap. Paper copies will be stored as outlined 
in this protocol.
16.10.
There will be data collected via a secure RedCap survey. Participants will 
be emailed a link to complete the questionnaires. This secure email will be sent

through RedCap and all data will be gathered through RedCap. RedCap is a 
secure web application frequently utilized to collect data for research, including 
HIPAA compliant information.
16.11. Not applicable. Data will not be collected by audio or video recording. 
16.12. Not applicable. No photographs of participants will be taken at any point 
during the study. 
17.Data and Specimen Banking
17.1. Not applicable. There will not be any data or specimen banking. 
17.2. Not applicable. This is not a multi-center study, nor will any data or specimens 
be banked. 
18.Risks to Subjects
18.1. This study involves risks to the participants as corticosteroids and Lipogems 
are both used by clinicians as part of the current standard of care for knee 
osteoarthritis. One potential risk that may arise is a breach in patient 
confidentiality. Although such a breach is unlikely to occur and should not 
negatively impact patient health or well-being, we will take precautions to 
minimize this risk. All investigators and members of the study team will strictly 
adhere to the HIPAA and patient confidentiality guidelines set forth by the 
hospital. All research staff will adhere to the guidelines set forth in the Data 
Management/Confidentiality portion of this protocol. 
Intra-articular knee injections, such as corticosteroids and Lipogems, are 
employed in routine clinical practice for the treatment of knee osteoarthritis. 
With any injection, there is a risk of local adverse reaction such as pain or 
swelling, and a risk of infection. In addition to an injection, Lipogems 
requires a lipoaspiration procedure from the patient’s abdomen. Some risks of 
lipoaspiration include seromas and hematomas requiring drainage, infections, 
changes to the skin including hyperpigmentation, scarring, or induration. Very 
rarely, more serious complications (including skin necrosis or local anesthetic 
toxicity) may arise. 24,25
18.2. We have received input from a board certified plastic surgeon on the risks of 
lipoaspiration. We have also reviewed the existing literature. Corticosteroid 
injection is part of the standard of care for treating knee osteoarthritis. As 
Lipogems is still a relatively new treatment option, there may be unforeseen 
risks.
18.3. Patients who are pregnant will not be eligible for participation. Patients must 
verbally confirm they are not pregnant prior to enrollment in the study and 
prior to receiving their injection.
18.4. Not applicable. There are no risks to others who are not subjects.

and intra-articular corticosteroid injections for symptomatic knee osteoarthritis: 
a randomized, placebo controlled study”
Page 17 of 40
Version Date: March 29, 2018
18.5. To minimize risk, all injections will be performed following standard of care 
sterile techniques and treatment guidelines. We will have a board certified 
plastic surgeon trained in lipoaspiration train the study investigators 
accordingly. To protect patient confidentiality, we will take the necessary 
precautions to protect patient data. All electronic files will be password 
protected and stored on a password protected computer behind a locked door. 
All paper documents will be kept in a locked filing cabinet in a locked office. 
19.Potential Benefits to Subjects
19.1. Potential benefits include the possibility of reduced pain and/or increased 
functionality of the affected knee after injection with Lipogems or 
corticosteroids. 
20.Recruitment Methods
20.1. Upon funding and IRB approval, participants will be recruited from the patient 
population at the clinics of Dustin Richter, MD, Robert Schenck, MD, and Suki 
Pierce, PA-C at the University of New Mexico Hospital’s Orthopaedic 
Department. Patients at these clinics are independently seeking evaluation of 
orthopaedic problems. The participating clinicians and research staff will 
screen the patients for inclusion during their standard examination.
20.2.
Review of relevant prior medical records (x-ray’s, primary care/referring 
physician evaluations, and orthopaedic records including current visit 
findings and imaging) will be conducted to screen for eligible 
participants.
20.3. Subjects will be recruited by participating physicians and research staff via 
word of mouth at pre-existing patient visits. If we are having difficulty with 
subject recruitment, we may consider advertising.
Additionally, a non-publically-displayed patient flyer will be created to relay 
brief, informative details about the study design to surgical staff (eg, patient 
inclusion/exclusion criteria, follow-up length, etc). 
21.Provisions to Protect the Privacy Interests of Subjects
21.1. All discussion of the study, including the informed consent process, will be 
conducted in a private exam room with only the clinician, relevant research 
staff, and patient in the room. All procedures and follow-up visits will be 
performed in private exam rooms with only the patient, the clinicians, necessary 
medical personnel, and necessary research staff present. Investigators will 
abide by standard patient confidentiality practices and will adhere to HIPAA 
protocols. 
21.2. All discussion of the study, including the informed consent process, will be 
conducted in a private exam room with only the clinician, relevant research 
staff, and patient in the room. All procedures and follow-up visits will be

22.2. There are no additional costs to participants. 
22.3. The study will pay for all procedures and drugs involved in the study, including: 
corticosteroids and Lipogems. Lipogems has agreed to cover the costs of 
the kits for all study participants randomized to receive Lipogems.
22.4. While we do not anticipate any serious adverse events, there are risks involved 
with undergoing medical procedures. Corticosteroid injections are currently 
included as part of the standard of care for treating osteoarthritis of the knee, 
and Lipogems is FDA approved for autologous use in orthopaedic surgery. 
Thus, any adverse events experienced by the patient will fall under insurance 
coverage for standard of care procedures. All adverse events will be reported 
as required by the University. Depending on the severity of event, the 
investigators will consider the adverse event and reserve the right to hold 
enrollment or close the study early.
22.5. See consent form for discussion of costs.

23.Compensation
23.1. Participants will be compensated for their participation by receiving a 
reloadable gift card. They will receive $25 at each in person follow-up visit. 
They will be compensated $10 each time they complete the online surveys. Each 
participant will be asked to return for 2 follow-up visits (6 weeks and 6 months, 
post-procedure) and complete the online surveys 3 times for a total of $80 
compensation for participating. 
24.Compensation for Research-Related Injury
24.1. If a patient elects to withdraw from the study, i.e. for further treatment/care 
elsewhere, the patient may withdraw. We do not anticipate any more risk than 
standard of care would provide to the patient. The patient can elect to pursue 
standard of care treatments as determined by the patient and their physician.
24.2. Study subjects will be monitored at follow-up appointments. If a subject is 
unhappy with their treatment outcome throughout the course of the study, they 
may elect to withdraw from the study and pursue their own care with the 
physician of their choice.
25.Consent Process
25.1. Participants must provide research staff with informed consent prior to 
enrolling in the study. 
25.1.1. Consent may be obtained by Dr. Richter, Dr. Schenck, Dr. Veitch, Dr. 
Wasserburger, and Lauren Faber and any other approved investigators 
listed in the Click IRB record. The process for obtaining informed consent 
and consent form will be reviewed with each member of the research staff 
responsible for obtaining consent by Dustin Richter, MD.
25.1.2. Consent will take place at the various clinics/hospitals associated with the 
University of New Mexico Hospital and the Orthopedics Department. 
Consent will only be obtained in a private patient room. No one besides 
the patient and study staff will be in the room at the time of consent. If the 
patient requests a family member or friend be in the room during the time 
of their appointment/consent, the patient’s request will be honored. 
25.1.3. The study, possibly treatment outcomes, and follow-up requirements will 
be explicitly stated at the time of consent. The patient will be made aware 
of their standard of care treatment options and will also be invited to 
participate in the study. The consent process will emphasize that patients 
have the right to accept or deny entry into the study with no consequences 
on their care. 
25.1.4. Potential subjects will be offered the choice to participate if they meet 
eligibility criteria at visits with their provider prior to enrollment in the

study. The study will be explained at that time. If the patient is interested, 
informed consent will happen at that time. 
25.1.5. Patients will provide consent for participation prior to enrolling in the 
study. This consent covers the injection and all follow-up visits. At each 
visit, participants will be asked if they wish to continue in the study and 
will provide verbal consent. 
25.1.6. During informed consent, the person obtaining consent will utilize teach-
back and ask the patient to explain, in their own words, what the study 
entails and what they are consenting to.
25.1.7. People obtaining consent will utilize teach back to make sure that patients 
understood the study, what possible treatment outcomes are, and what 
follow-up is required of study participants. 
Subjects not fluent in English
25.1.8. This study will also include Spanish speaking participants.
25.1.9. For informed consent, explanation of the study, and all visits thereafter, a 
translator will be available to translate for the patient and the clinician. 
The informed consent document will be translated to Spanish.
25.1.10. Not applicable. No short-form consent documents will be used. There 
will be one standard informed consent document that must be explained to 
the patient and read by the patient prior to enrollment. 
Cognitively Impaired Adults/Adults Unable to Consent/Use of a Legally 
Authorized Representative
25.1.11. Not applicable. This study will only be enrolled individuals with full, 
independent ability to provide legally effective consent. 
25.1.12. All subjects are required to have full, independent ability to provide 
legally effective consent. 
25.1.13. During the consent process, those obtaining consent will utilize teach-
back to ensure that the individual understands what participation in the 
study entails. Individuals will be asked to explain, in their own words, 
what they are agreeing to before giving informed consent. For individuals 
who are Spanish speaking, an interpreter will be made available to help 
with the consent process. If an individual is unable to explain the study or 
verbalize what they are agreeing to, he/she will not be enrolled.

A. Device Name:  Lipogems System
B. Manufacturer:  Lipogems International S.p.A.
C. Does the research involve a Significant Risk Device under an IDE?
 Yes. 
 No
D. Is the research IDE-exempt?
 Yes.
Lipogems is marketed as an autologous adipose tissue transfer system. It has been 
cleared by the FDA twice, most recently on November 4th, 2016. In the most recent 
clearance, Lipogems has been approved for harvest, concentration, and transfer of 
autologous adipose tissue for use in orthopaedic and arthroscopic procedures. Thus, it 
is considered on-label for those applications. The term “stem-cell” is not used as the 
device does not separate cells and tissue and all original components of the adipose 
tissue are present in the final concentrate after processing. In the clearance, it is stated 
that the cells and tissue microarchitecture are preserved, constituting a minimally 
manipulated product. With the existing FDA clearance, injection into the knee for 
arthritis or pain relief is considered within the scope of Lipogems.
 No
E. Does the research involve a Non-Significant Risk (NSR) Device?
 Yes.

Evaluating the efficacy of micro-fragmented adipose tissue and intra-articular corticosteroid 
injections for symptomatic knee osteoarthritis: a randomized, placebo controlled study
11/07/2019
Purpose and General Information
You are being asked to participate in a research study that is being done by Dustin Richter, MD, who is the 
Principal Investigator, and his associates.  This research is being done to evaluate the efficacy of 
corticosteroids and Lipogems injections for knee osteoarthritis in comparison to placebo. Corticosteroids 
are one of the current standard of care options to treat knee osteoarthritis. Lipogems is an FDA approved 
device for use in orthopaedics and arthroscopy procedures. You are being asked to participate because 
you have symptomatic osteoarthritis of the knee.  Approximately 75 people will take part in this study at the 
University of New Mexico. Lipogems will be donating kits for this study.
This form will explain the study to you, including the possible risks as well as the possible benefits of 
participating.  This is so you can make an informed choice about whether or not to participate in this study.   
Please read this Consent Form carefully. Ask the investigators or study staff to explain any words or 
information that you do not clearly understand. 
What will happen if I participate? 
If you agree to be in this study, you will be asked to read and sign this Consent Form. After you sign the 
Consent Form, the following things will happen:  You will be enrolled in the study, which requires six 
activities: one procedure, two brief follow-up appointments, and three sets of online surveys. Upon 
enrollment, you will be randomized to receive one of three treatment options: Lipogems, steroid injection, 
or placebo. Participants who are assigned to receive Lipogems will know, because this procedure requires 
a lipoaspiration (fat tissue removal) from the abdomen followed by reinjection into your knee. Participants 
who are assigned to receive either a steroid injection or a placebo injection will not know whether they are 
getting a steroid or placebo until the end of the study. After you are assigned to a group, you will be 
scheduled for your procedure. At the procedure, you will fill out three surveys about the pain in your knee 
and how it affects your daily life and a medication log. You will then receive your injection. You will be 
scheduled for two follow-up appointments: six weeks later and six months later. You will be asked to 
complete the same three surveys at each follow-up visit. You will be emailed these same surveys and 
medication log again two weeks after your injection, three months after, and one year after. After 
completion of your one year questionnaire, you will be told what group you were assigned to. If you were 
assigned to receive placebo, you may elect to have a corticosteroid injection at this time. Your participation 
in the study will be complete after your one year follow-up visit.   
Participation in this study will take a total of up to a maximum of eight hours over a period of one year.
What are the possible risks or discomforts of being in this study?
Every effort will be made to protect the information you give us.  However, there is a small risk of loss of 
privacy and/or confidentiality. Although a breach in patient confidentiality is unlikely to occur and should 


                                                     Page 2 of 5                                    Version Date: 11/07/2019
not negatively impact your health or overall well-being, the necessary precautions will be taken to minimize 
this risk. 
Otherwise, Intra-articular knee injections, such as corticosteroids and Lipogems, are employed in routine 
clinical practice to treat knee osteoarthritis. With any injection, including steroid injections, there is a risk 
of local adverse reaction such as an allergic reaction, increased pain or swelling, and a risk of infection that 
may be deep in the joint and lead to septic arthritis. Other risks of steroid injections include a higher sugar 
concentration in your blood for up to 3 days, skin discoloration, thinning of the layer of fat cells under your 
skin, and facial flushing. Some patients have weakening of the tendons or ligaments that may lead to them 
breaking. In addition to an injection in the knee, Lipogems involves a lipoaspiration procedure, which is 
the removal of fat cells like what is done during a liposuction, from the patient’s stomach. Some risks of 
lipoaspiration include the development of a fluid pocket or collection of blood in the area that may need 
to be drained, infections, and changes to the skin such as a scar, an area of darker skin compared to the 
surrounding skin, or a small area of skin hardening. Very rarely, more serious complications may arise, 
including but not limited to irritation of skin tissues leading to death of the cells or a localized toxic reaction 
to the anesthetic medication that is used to make the stomach numb for the removal of fat cells. 
How will my information be kept confidential?
Your name and other identifying information will be maintained in locked files, available only to authorized 
members of the research team, for the duration of the study.  For any information entered into a computer, 
the only identifier will be a unique study identification (ID) number. Any personal identifying information 
and any record linking that information to study ID numbers will be destroyed two years after data 
collection has ended for the entire study. Your paper documents will be shredded and disposed of, and 
any computerized files will be deleted.  Information resulting from this study will be used for research 
purposes and may be published; however, you will not be identified by name in any publications.
Information from your participation in this study may be reviewed by the investigators, federal and state 
regulatory agencies, and by the UNM Human Research Review Committee (HRRC) which provides 
regulatory and ethical oversight of human research. There may be times when we are required by law to 
share your information. However, your name will not be used in any published reports about this study.
What are the benefits to being in this study?
There may or may not be direct benefit to you from being in this study. Some patients may experience 
reduced pain or increased joint functionality of the affected knee after injection. However, your 
participation may help find out which knee injection is the superior treatment for other patients with knee 
osteoarthritis.
What other choices do I have if I don’t participate?
Taking part in this study is voluntary so you can choose not to participate. You and your clinician can still 
discuss other options for treatment of your knee pain. There are a variety of different treatment options 
available to explore and the choice depends on your medical history, your desires, and your clinician’s 
medical expertise. Some options include: NSAIDs (like aspirin or ibuprofen), steroid injections, other 
forms of injections that are not steroids, or a total knee replacement surgery. If you choose not to 
participate, your clinician will still review your medical history, your current complaints, and other medical 
information available to them to help you choose a treatment option.
Will I be paid for taking part in this study?
