Study Summary
Background: 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. Methods/Design: One hundred and twenty individuals, over the age of 45, who seek outpatient Physical Therapy (PT) following a unilateral TKR will be randomized into a control and intervention group. The intervention group will receive a weekly physical activity intervention during PT, which includes a FitbitTM monitor, individualized step goals, and face-to-face feedback provided by the physical therapist. Efficacy of the intervention will be measured by minutes/week spent in Moderate-to-Vigorous Physical Activity (MPVA) using an Actigraph GT3X monitor from enrollment to discharge, 6 months and 12 months from discharge from PT. The association of self-efficacy for exercise and kinesiophobia with physical activity will also be measured at the same time points. Fidelity and safety of the intervention will be assessed during outpatient PT. Discussion: 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 disch
