Movement Pattern Biofeedback Training After Total Knee Arthroplasty

This study aims to improve rehabilitation outcomes after total knee arthroplasty (TKA) by addressing persistent atypical movement patterns that often develop after surgery. These movement patterns, which are associated with quadriceps weakness and poor physical function, also lead to increased strain on the contralateral knee, potentially accelerating the progression of knee osteoarthritis (OA) in the opposite leg. The study will conduct a randomized controlled trial to evaluate whether adding a novel movement pattern training program (MOVE) to contemporary progressive rehabilitation can improve functional movement quality more effectively than rehabilitation alone (CONTROL). Participants will be assessed at multiple time points after TKA, including pre-operatively, 2 months, 6 months, and 2 years. The primary outcome will focus on improving the surgical knee extension moment, which will be measured during various functional tasks like walking and stair stepping. Secondary outcomes include assessing improvements in physical function and evaluating the potential reduction in the progression of contralateral knee OA. This study aims to advance rehabilitation strategies by incorporating motor learning principles to not only improve knee movement patterns but also enhance overall functional recovery and prevent further knee degeneration.
