The receiver operating characteristic curves of notch width index (Area Under ROC Curve= 0.739, 95% CI = 0.677–0.801, P < 0.001); notch height index (Area Under ROC Curve= 0.603, 95% CI = 0.533–0.672, P = 0.005); β angle (Area Under ROC Curve= 0.796, 95% CI = 0.740–0.851, P < 0.001) and lateral tibial slope (Area Under ROC Curve= 0.760, 95% CI = 0.698–0.822, P < 0.001). CI: Confidence interval; α angle: The notch angle; β angle: The angle formed by the Blumensaat line and the long axis of the femur; ROC:Receiver operating characteristic curve
