Preoperative Predictors of Persistent Impairments During Stair Ascent and Descent After Total Knee Arthroplasty

摘要

Background:Although total knee arthroplasty improves functional mobility in persons with end-stage knee osteoarthritis, many subjects have reported continued difficulty with stair ascent and descent after surgery. The purpose of the present study was to determine preoperative predictors of handrail use during stair ascent and descent following primary unilateral total knee arthroplasty.
