Patient Satisfaction versus Patient Reported Outcomes
Authors: Angthong Chayanin 
Published: September 2018

Category: Other Introduction/Purpose: Several researches focused on patient reported outcomes (PROs), however, little is known about the actual correlation between the patient satisfaction and PROs. The present study is to determine the correlation between patient satisfaction and PROs. Methods: A total of 35 patients with foot and ankle disability participated in this study to complete the data in terms of the patient satisfaction score and PROs. All of them were treated by a single foot and ankle surgeon. The Thai patient satisfaction score or Foot and Ankle Satisfaction Score [FASS] (0 [worst] -100 [best]) consisted of 4 items regarding patient’s perspectives as 1) symptoms, 2) function, 3) other complaints, and 4) recommendation of his/her treatment for other patients. PROs measures consisted of validated Thai visual analogue scale foot and ankle (VASFA) (0 [worst] -100 [best]) and Thai Short Form-36 (SF-36) (0 [worst] -100 [best]). Results: Mean total FASS was 92.0 ± 11.8, 87.7 ± 17.0, 98.6 ± 6.0, 98.6 ± 8.5 and for the items: symptoms, function, other complaints, and recommendation of his/her treatment for other patients, respectively. Mean total FASS was 94.2 ± 6.8. Mean VASFA was 67.7 ± 18.3. Mean SF-36 was 82.7 ± 10.7.There were no significant correlations between mean total FASS and PROs (VASFA [p-value < 0.05], SF-36 [p-value <0.05]). There were no significant correlations between mean FASS in all items and PROs (VASFA, SF-36) with all p-values < 0.05. The significant correlation was found between VASFA and SF-36 (Pearson correlation coefficient = 0.734; p-value<0.01). Conclusion: One of the successful treatment results is the improvement of patient satisfaction. Even if several researches focused on the assessment of PROs to achieve the successful outcome, this kind of measures was no significant correlation with patient satisfaction. PROs were not able to reflect the patient satisfaction following treatments. Patient satisfaction may be related to other parameters, in addition to the PROs, such as the patient expectation, the post-treatment level of physician-patient relationship, the patient’s confidence in his/her physician capability, etc. Further study is needed to clarify these factors.

Published: September 2018

Category: Arthroscopy Introduction/Purpose: Various operative procedures have been used to treat osteochondral lesions of the talus. Among the new alternatives to treat these lesions, Autologous Matrix-Induced Chondrogenesis (AMIC®) has proven to provide satisfactory results through medium-term follow-up. The aim of this study is to report early post-operative clinical results of patients submitted to the AT-AMIC® technique and autologous bone graft, when necessary, for OLT’s at a six-month minimum follow-up. Methods: This is case series of 17 consecutive patients that were submitted to AT-AMIC®, between january of 2016 and april of 2017. 9 men and 8 women, between 15 and 67 years were diagnosed with OLTs with the typical history of deep ankle pain and corresponding magnetic resonance imaging injury. Surgery was proposed only after failure of conservative treatment of at least 3 months. Surgeries were performed by three different surgeons, with high arthroscopic experience. Patients answered the AOFAS score preoperatively and at the last follow-up, ranging from 6 to 18 months Results: Average size of OLTs were 1,12 cm2, with Raikin 4 location being the most common (70,5%). Calcaneal osteotomy was the most common associated procedure, with 17,6%. Average follow-up was 10,76 months. Average AOFAS before surgery was 46,35, increasing to 89,53 at the last follow-up. This difference was statistically significant with a p-value of <0,001. No complications were observed and no changes in the post-operative protocol were needed. Conclusion: AT-AMIC® is a reliable and reproducible method of treatment for OLTs, reaching high clinical postoperative scores, with a very low rate of complications. Further comparative study is needed to prove its efficacy.

Category: Ankle Arthritis Introduction/Purpose: Total ankle arthroplasty (TAA) is gaining popularity as an alternative to ankle arthrodesis in the setting of end-stage ankle arthritis. However, compared to hip and knee arthroplasty, there is a relative dearth of evidence to support its use. This study assesses the quality of literature surrounding modern TAA designs. Methods: A search of all peer-reviewed, English-language journals was conducted to identify publications involving TAA. The initial search identified 444 articles published during 2006-2016. Of these, 182 were excluded because they were not clinical outcomes studies, 46 because the TAA implant was no longer available, and 15 because the primary outcome of the study was not related to TAA, leaving 201 articles for analysis. Results: No Level I studies were identified. Seventeen (8%) studies were Level II, 48 (24%) Level III, 128 (64%) Level IV, and 8 (4%) Level V. One hundred forty-three studies (71%) were retrospective in nature. Stratification by study design revealed 128 (64%) case series, 33 (16%) experimental cohort studies, 19 (10%) case-control studies, 13 (6%) observational cohort studies, and 8 (4%) case reports. The number of studies published each year steadily increased from 2006 to 2016. A total of 51% of TAA research was published in only two journals: Foot and Ankle International and the Journal of Bone and Joint Surgery. Publications from the United States accounted for 36% of total publications. The most published implant was the Scandinavian Total Ankle Replacement (Figure 1). Conclusion: While the number of TAA studies published each year has steadily increased since 2006, the quality of this research as measured by level of evidence remains suboptimal. This analysis highlights the need for continued improvement in methodology and development of robust prospective registries to advance our knowledge of TAA as a treatment for end-stage ankle arthritis.

Published: September 2018

Category: Midfoot/Forefoot Introduction/Purpose: The average intramedullary diameter of the proximal phalanges of the foot has not been well documented in the literature. This dimension has important implications for surgical fixation devices, such as intramedullary screws. By design, intramedullary fixation devices rely on endosteal fit to provide stability. The precise intramedullary diameter is not readily identifiable on plain radiographs. A better understanding of the average diameter of the proximal phalanges of the foot can assist surgeons in surgical planning and appropriate screw diameter selection to provide more satisfactory patient outcomes. Methods: Twenty below-knee cadaveric specimens were dissected to expose each proximal phalanx. A sagittal saw was used to transect the diaphysis at its narrowest portion. The dorsal to plantar and medial to lateral diameters were measured using a digital manometer. Results: The average diameter dorsal to plantar for each digit was 6.25 ± 2.24 mm, 3.61 ± 1.25 mm, 2.94 ± 0.70 mm, 2.72 ± 0.77 mm, and 2.48 ± 0.80 mm, respectively. The average diameter medial to lateral for each digit was 7.83 ± 2.13 mm, 3.08 ± 0.93 mm, 2.47 ± 0.74 mm, 2.33 ± 0.73 mm, and 2.62 ± 0.69 mm, respectively. The overall average diameter for toes one through five was 7.04 ± 1.95 mm, 3.35 ± 1.04 mm, 2.71 ± 0.66 mm, 2.52 ± 0.71 mm, and 2.55 ± 0.63 mm, respectively. Conclusion: Understanding the intramedullary diameters of the proximal phalanges of the foot is a valuable tool when utilizing intramedullary surgical stabilization. The hallux proximal phalanx demonstrated the largest, and most variable, diameter, which could make selection intramedullary fixation difficult. In addition, the hallux proximal phalanx may lend itself better to 2 smaller fixation devices rather than one larger one. The lesser phalanges demonstrated smaller diameters more consistently, which is more amenable to a single smaller (2.5 mm) intramedullary device. This data can provide surgeons with an expected intramedullary diameter during surgical planning.

Category: Ankle Introduction/Purpose: Workers’ compensation (WC) has been associated with poor outcomes following a variety of injuries and surgeries. Previous studies have investigated surgical outcomes via satisfaction surveys, but rates of subsequent injury following surgery have not been specifically studied. The purpose of this study was to investigate the rates, locations and risk factors for subsequent injuries in WC patients and non-WC patients who underwent the same surgeries. Methods: With IRB approval, we identified the records of patients with a foot or ankle surgery performed by a single surgeon from 2009-2015. We included only surgeries with one of the most common current procedural terminology (CPT) codes from the WC population. A retrospective chart review was performed on all WC and non-WC patients with at least one of these CPT codes. A subsequent injury was defined as a new injury at a different anatomical location that occurred from 2 months to 2 years after the index surgery. Chi-square and two-tailed t-tests were used to compare WC and non-WC patient populations, and to determine factors associated with subsequent injuries. Results: Overall, the WC population had higher rates of subsequent injury than the non-WC population 23.21% versus 7.27%, p=.0011. Within the WC patient population, patients with subsequent injuries were older than patients without subsequent injuries 48.78±7.30 versus 41.58±12.40, p=.0137. In a blinded review of the charts and Iowa Courts Online, legal representation was found to be more common in WC patients with subsequent injuries than WC patients without subsequent injuries (76.92% versus 37.21%, p=.0240). In the non-WC population, there were more males in the group without subsequent injuries than in the group with subsequent injuries 42.48% versus 8.33%, p=.0287. There were no significant differences in locations of subsequent injury. Hip, knee and contralateral foot and ankle were common areas of subsequent injury in both groups. Conclusion: Overall, WC patients had higher rates of subsequent injury than non-WC patients. Within the WC group, legal representation further raised the risk of subsequent injury. Gender may mediate variable reporting of subsequent injuries in non-WC populations. While the reason for this increased risk of subsequent injury is not known, the differences are enough that they should be considered when counseling WC patients considering these surgeries. Additionally, if further study supported these findings, knowledge of the areas at risk for subsequent injury might lead to preventative strategies that could decrease the risk of subsequent injury.

Category: Hindfoot Introduction/Purpose: Plantar fasciitis is a debilitating problem that can cause long-term pain. Multiple different studies with various modalities have been suggested to treat the inflammation of the plantar fascia. None of them have provided a cause for the inflammation. A few recent studies have shown gastrocnemius equinus to be a driving factor in foot pain, which includes plantar fasciitis. Our belief is that the inflammation is due to a stretch placed on the plantar fascia due to a gastrocnemius equinus contracture and the beginning of an arch collapse per the Grand Rapids arch collapse model. As such, we wanted to review our results with an isolated gastrocnemius recession for the treatment of plantar fasciitis. Methods: We retrospectively reviewed patient data collected by isolating ICD-9 and ICD-10 codes for plantar fasciitis. These patients presented to the senior author’s office with a complaint of plantar heel pain, were diagnosed with a gastrocnemius equinus contracture and plantar fasciitis, failed conservative treatment, and opted for an isolated gastrocnemius recession as a definitive treatment of the fasciitis. From the timeframe of 1/1/2015 to 6/12/17, there were 68 out of 97 patients who qualified for the study based on the necessary criteria: an initial consultation pain score, initial post-operative pain score at two weeks, and second post-operative pain score at eight weeks. These patients did not have coexisting surgeries at the time of the gastrocnemius recession or prior surgery to the area in discussion. Results: For the 68 patients (five of which underwent bilateral procedures at a minimum of six weeks apart), who elected to have a gastrocnemius recession for plantar fasciitis, the average initial presenting pain was a 7.4 on a scale of 0 to 10. The average initial post-operative pain score was 2.8 and the average second post-operative pain score was 3.3. The average number of days from initial to second post-operative appointment was 136 days. Of the 68 patients, 21 returned after their eight-week post-operative visit for evaluation. Only 3 returned with recurrent plantar heel pain, 4 more presented with new onset tarsal tunnel syndrome, three more with heel pain different from their pre operative pain and the remaining patients had new onset unrelated pain. Conclusion: We have demonstrated that an isolated gastrocnemius recession can decrease the pain score in patients with recalcitrant plantar fasciitis. Follow up care beyond eight weeks post operation is not routinely performed due to the limited nature of the procedure. The improvement demonstrated in the VAS scores of the patients included in this study show a definite improvement and as such, we believe that an isolated gastrocnemius recession should be considered as a definitive treatment of plantar fasciitis. Future prospective randomized studies will need to be completed to further evaluate the effectiveness of this procedure.

Published: September 2018

Category: Other Introduction/Purpose: Measuring patient outcomes is a critical piece toward advancing medical care. A previous study reviewing the commonly obtained outcomes measures used in orthopaedic foot and ankle surgery (Hunt 2013) demonstrated the AOFAS clinical rating scale was the most commonly reported measure over the past 10 years (2002-2011). Since that time, the American Orthopaedic Foot and Ankle Society published a position statement recommending against the continued use of this rating scale. The purpose of this study is to determine the impact of this position statement on the continued use of this invalidated instrument. Methods: We systematically reviewed all foot and ankle articles published in six major orthopaedic journals between 2012 and 2017. Any clinical study utilizing outcome measures was included. All outcome measures, level of evidence, type of study, study date and topic were recorded. The current utilization of the AOFAS was compared to the prior published percentages (outcome measure/total number of clinical articles) to determine the impact of use over time. Results: A total of 660 foot and ankle articles using clinical outcome measures were identified from a total of 14,164 articles published from the six journals between 2012-2017. Of the 108 outcome measures used, the 6 most common were the AOFAS (57.42%), Pain VAS (38.33%), SF-36 (18.18%), FAOS (8.79%), SF-12 (6.67%) and FFI (6.67%). Compared with Hunt et al. 2013, there is a consistently high usage of the AOFAS clinical rating scale during the past 5 years. A unique finding was more clinical studies were using two or more measures (59.09%) than a single outcome measure (40.91%). The majority of the studies represented level IV evidence (55.91%) with only 7% Level I (Hunt et al. 70% and 9.4% respectively). Conclusion: There continues to be a wide variety of outcome measures used in foot and ankle clinical studies. There are more higher evidence (Level II and III) studies completed in the past 6 years than prior years. The purpose of the AOFAS position statement was to discourage the use of the AOFAS clinical rating scales. Although this did not occur, there was a shift from the isolated use of one to multiple different outcome measures. As researchers become more comfortable with other validated outcome measures, hopefully the use of the AOFAS clinical rating scale will decline.

Category: Sports Introduction/Purpose: Adequate evaluation of foot and ankle problems in elite athletes is paramount for planning the correct treatment, predicting clinical prognosis and supporting decision making. A complete physical examination that includes the assessment of foot alignment during weightbearing is mandatory. The three-dimensional evaluation provided by weightbearing CT imaging (WBCT) represent an important diagnostic tool for foot and ankle surgeons when dealing with these extremely physically active patients. The purpose of this study was to assess different WBCT measurements of hindfoot and forefoot alignment in injured high-level football and basketball players. We hypothesized that specific patterns of hindfoot alignment and height of the longitudinal arch of the foot could be identified. Methods: In this single center retrospective comparative study, 80 professional male athletes - 47 basketball and 33 American football players from College, NBA and NFL leagues - that underwent WBCT as part of the clinical investigation for different injuries of the foot and ankle were included in the study. WBCTs images were evaluated by a blinded board-certified foot and ankle orthopedic surgeon. Multiple measurements used for assessment of hindfoot valgus and longitudinal arch height were assessed and included: foot and ankle offset (%), calcaneal offset (mm), hindfoot alignment angle (°), navicular-floor distance (mm), medial cuneiform-floor distance (mm), forefoot arch angle (°), inferior talar-superior talar angle (°), and subtalar horizontal angle (°). An unpaired Student’s t test was performed to evaluate any differences in the measurements when comparing professional basketball and football patients. P-values less than 0.05 were considered significant. Results: A summary of demographic characteristics and each measurement’s distributions and standard deviations, as well as p-values for the analysis between groups, is given in table 1. No significant differences were found between basketball and American football elite athletes when comparing the mean values of measurements evaluated (mean differences): foot and ankle offset (0.26%), calcaneal offset (0.58 mm), hindfoot alignment angle (0.73°), navicular-floor (0.35 mm) and medical cuneiform-floor distances (0.38 mm), forefoot arch angle (0.74°), inferior talar–superior talar angle (0.83°) and subtalar horizontal angle (0.1°). Conclusion: Although we did not find significant differences in foot alignment when comparing basketball and American football professional athletes, the results of our study highlight some of the important foot alignment parameters and establish distributions in an extreme but important population. Further studies correlating foot alignment with the incidence of some of the most common pathologies diagnosed in elite athletes, such as the ones reported in our study, can help in the understanding and prevention of those injuries.

Published: September 2018

Category: Ankle Arthritis Introduction/Purpose: During internal fixation of ankle fusions, besides the standard crossed screw fixation pattern, the use of a percutaneously placed augmenting screw, directed from the posterolateral tibial metaphysis proximally across the ankle into the talar neck (“ankle fusion home run screw”), is a widely used technique. The placement of this screw is technically demanding and multiple attempts under fluoroscopy guidance are frequently needed to achieve a perfect positioning of the implant. Injuries to local neurovascular and tendinous structures might happen. The objective of this cadaver study was to identify the number of attempts necessary for a perfect positioning of the ankle fusion home run screw and the neurovascular and tendinous structures at risk. Methods: Eleven fresh frozen cadaver limbs were used. Guide wires (3.2 mm) from the Stryker (Selzach, Switzerland) 7.0-mm headless cannulated set were percutaneously placed into the distal posterolateral aspect of the leg, under fluoroscopic guidance, with the ankle held in neutral position. Mal positioned pins were not removed and served as guidance for the following pins. The number of guide wires needed to achieve an acceptable positioning of the implant was noted. After a layered dissection from the skin to the tibia, we evaluated neurovascular and tendinous injuries, and measured the shortest distance between the closest guide pin and the soft tissue structures, using a precision digital caliper. Results: The mean number of guide wires needed to achieve and acceptable positioning of the implant was 2.09 (SD 0.83, range 1- 4). The mean distances between the closest guide pin and the soft tissue structures of interest were: Achilles tendon 6.90 mm (SD 3.74 mm); peroneal tendons 9.65 mm (SD 3.99 mm); sural neurovascular bundle 0.97 mm (SD 1.93 mm); posteromedial neurovascular bundle 14.26 mm (SD 4.56 mm). Sural bundle was in contact with the guide pin in 5/11 specimens (45.5%) and transected in 3/11 specimens (27.3%). Conclusion: The placement of percutaneous ankle fusion home run screws is technically demanding and multiple guide pins are needed. Our cadaveric study showed that important tendinous and neurovascular structures are in close proximity with the guide pins and that the sural bundle is injured in approximately 73% of the cases. Caution should be taken during percutaneous placing of screws and an appropriate approach and surgical dissection to bone is advised.
