SD: standard deviation; HKAA: hip-knee-ankle angle; LDFA: lateral distal femoral angle; MPTA: medial proximal tibial angle; FVA: femoral valgus angle. The significance threshold for one-way analysis of variance (ANOVA) was set at . Tukey’s honestly significant difference (HSD) was used for post hoc analysis. The significance threshold for Pearson’s chi-square test was set at .
