Preoperative hand-grip strength can be a predictor of stair ascent and descent ability after total knee arthroplasty in female patients

摘要

Background: Hand-grip strength was reported to be important predictor of functional limitation and disability related to low muscle strength in old people. The purpose of this study was to determine whether preoperative hand-grip strength predicts stair ascent and descent ability after total knee arthroplasty (TKA).
