^aR = 0.942, R ² = 0.888, adjusted R ² = 0.885; P < .05. Bold P values indicate statistical significance (P < .05). DV, dependent variable; JLCA, joint-line convergence angle; ΔJLCA, difference in JLCA between standing-leg and valgus stress radiographs; RCA, real correction angle; TCA, target correction angle.
