Study Description
The definitive treatment for knee osteoarthritis is Total Knee Replacement (TKR), which results in clinically meaningful improvements in pain and physical function. However, evidence suggests that physical activity remains unchanged after TKR. This randomized clinical trial is investigating the efficacy, fidelity, and safety of a physical therapist administered physical activity intervention for people after TKR.
This study is designed to fill a critical clinical need to increase physical activity after TKR. The primary objective of the study is to evaluate the efficacy of a physical therapist administered physical activity intervention for people after TKR. The secondary objectives are to evaluate the fidelity and safety of a physical therapist administered physical activity intervention for people after TKR and to investigate changes in self-reported and performance-based physical function after a physical therapist administered physical activity intervention for people after TKR. The tertiary objective is to explore the association of psychosocial factors with physical activity 6 and 12 months after discharge from a physical therapist administered physical activity intervention for people after TKR. The findings will be used to support a large multi-site clinical trial to test the effectiveness, implementation, and cost of this intervention.
