Data are presented as the mean value ± standard deviation; WBL%, weight-bearing line ratio; HTO, high tibial osteotomy; SV, slight valgus; MV, moderate valgus; LV, large valgus; HM, medial heel; HC, central heel; M, metatarsal; MLPR, medial-lateral pressure ratio; *compared with preoperative values, P < 0.05
