Effectiveness of prehabilitation on outcomes following total knee and hip arthroplasty for osteoarthritis: a systematic review and meta-analysis of randomized controlled trials

PURPOSE: To quantify the effectiveness of prehabilitation prior to total knee and hip arthroplasty (TKA/THA) for osteoarthritis on postoperative outcomes assessed by self-report and performance-based measures. METHODS: Embase, MEDLINE, CENTRAL, CINAHL and Scopus (inception-August 2022) were searched for randomized controlled trials. Self-report outcomes were function, health-related quality of life (HRQoL), and pain. Performance-based outcomes were strength, range of motion (ROM), balance, and functional mobility. The RoB 2.0 assessed risk of bias. Random-effects meta-analysis was performed up to 52 weeks after TKA/THA. RESULTS: = 2) for THA. CONCLUSION: High risk of bias and significant heterogeneity observed in our meta-analysis prevent conclusions regarding prehabilitation effectiveness on outcomes up to one year after TKA/THA.
