Evaluation of the balance function before and after total knee arthroplasty using Berg balance scale

摘要

Abstract Introduction The purpose of this study was to evaluate balance function before and after total knee arthroplasty (TKA) using Berg balance scale (BBS). The study also aimed to identify factors associated with balance impairment.Materials and methods Ninety-three knees in 90 patients were prospectively evaluated using their BBS scores, passive knee extension/flexion angles, Visual analogue scale for pain scores, hip–knee–ankle angles, and knee extensor/flexor muscle strengths before and after TKA. A total BBS score of less than 45 indicates an enhanced risk of multiple falls. Multivariate logistic regression models were performed to elucidate factors associated with post-operative BBS score.Results A significant difference in mean pre- and post-operative BBS scores were noted (49.3?±?6.4 vs. 52.2?±?4.7) (p?
