The purpose of this study is to examine the pre-post effects of a single ZILRETTA knee
injection on physiological measures of self-reported pain and disability, physical
performance, and physical activity in individuals with knee osteoarthritis (OA). The
investigators will recruit 35 symptomatic knee OA patients for this study. All data will be
collected prior to injection (baseline), as well as at 4 (post 1) and 8-week follow-ups (post
2).
