  1. Data are presented as the mean ± standard deviation with the range in parentheses. HKA: hip-knee-ankle; WBL: weight bearing line; mLDFA: mechanical lateral distal femoral angle; mMPTA: mechanical medial proximal tibial angle. The HKA angle with a negative value represents varus alignment. The WBL ratio with a negative value indicates that the mechanical axis of the entire leg passes medial to the medial edge of the tibial plateau
