Fig. 3From: Improved knee biomechanics among patients reporting a good outcome in knee-related quality of life one year after total knee arthroplastyReceiver operating characteristic (ROC) curves were calculated to evaluate the ability of change in knee gait biomechanics to correctly classify patients into either the good or poor outcome group. Poor outcome was defined as change below the minimally detectable change (21.1) in knee-related Quality of Life of KOOSBack to article page
