Performance-Based Outcome Measures in Total Knee Arthroplasty: A Systematic Review

Abstract Aims To present a comprehensive report of the psychometric properties of performance-based outcome measures in older adults with Total Knee Arthroplasty (TKA). Methods A literature search was carried out in PubMed, Scopus, and Web of Science electronic databases. The bias risk and methodological validity of the studies included in the study were analyzed using the four-point COSMIN tool. Results The systematic review contained 16 articles. Intra-rater reliability was presented in nine studies, validity in nine studies, calculation error in nine studies, inter-rater reliability in four studies, and responsiveness analysis in five studies. The floor-ceiling effect was not stated in any of the experiments. Conclusion The present systematic review demonstrated the quality and the evidence of physical performance-based outcome measures in TKA. All psychometric property analysis of studies has a “poor”, “fair” or “good” quality. Further studies should focus on inter-rater reliability, responsiveness, and floor-ceiling effect with higher sample size.
