Prospective Trial of the TriFit™ Web Knee Brace

Study Overview
=================
Brief Summary
-----------------
This is a prospective trial comparing improvements in pain, function, and quality of life in patients with early-stage knee osteoarthritis conservatively managed with the TriFit™ Web Knee Brace. The study design will represent a consecutive series of conservatively managed patients with knee-pain not yet candidates for surgical intervention and is non-comparative in nature.

Detailed Description
-----------------
This clinical study will be conducted at the Florida Orthopaedic Institute (FOI) beginning in 2017. The trial will be a prospective trial of a convenience sample of skeletally mature patients with knee pain treated by the Principal Investigator (Jeff Sellman, MD) at Florida Orthopaedic Institute with clinically and radiographically confirmed early stage knee Osteoarthritis that can be managed without surgical intervention. The study population will be defined as all adult patients (>21 years) seen by the Principal Investigator and diagnosed with knee osteoarthritis. All patients will be independent in activities of daily living. All patients will be seen in the Prinicpal Investigator outpatient clinic at Florida Orthopaedic Institute. Patients will be screened as candidates for enrollment into the study and if the patient satisfies the inclusion/exclusion criteria, a clinical research coordinator or the study Principal Investigator will explain all essential elements of the clinical trial. If the patient agrees to participate, the study coordinator or Principal Investigator will obtain informed consent. The patient will still be followed clinically for 12 months after initial brace application.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |

A short-form knee arthroplasty outcomes survey. | up to12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Visual Analogue Scale (VAS) (measures pain) | - A short-form to measure pain level knee arthroplasty outcomes survey. The scale is from 1-100 on a 10cm ruler, the higher the number equals more pain. | Baseline (screening) and compare at specific timepoints until 12 months | 
| Activity Restriction Scores | -A scale from 1-100, 1 being no activity, and 100 being active | up to12 month period | 
| Patient Satisfaction with Brace | Satisfaction is measured by 5 choices, very dissatisfied, dissatisfied, not dissatisfied or satisfied, satisfied, very satisfied. | up to 12 month course of study | 
| Analgesic use | Analgesic use for Knee pain, medications, Injections - to document subjects pain | up to12 month course of the study | 
| Compliance | Compliance - to document how many hours the brace is worn | up to 12 month course of the study |
