Gait parameters and plantar pressure were recorded preoperatively and 4 months postoperatively using the Zebris FDM pressure platform. Radiographic parameters—including the femorotibial angle (FTA), medial proximal tibial angle (MPTA), weight-bearing line ratio (WBLR), and tibial plafond inclination (TPI)—as well as clinical scores (VAS, HSS, WOMAC, and Lysholm) were assessed.ResultsPostoperative radiographic parameters and clinical scores significantly improved (P < 0.001). Stride length (P < 0.05), gait velocity, and affected-limb stance duration (P < 0.01) increased. COP path length (P < 0.001) and gait temporal symmetry indices (P < 0.01) decreased. Radiographic correction correlated with plantar-pressure variables (P < 0.05). Medial forefoot (M1) and medial heel (HM) contact time and peak pressure also increased (P < 0.05).ConclusionMOWHTO combined with APM was associated with improvements in lower-limb alignment, gait performance, plantar-pressure distribution, and gait symmetry during the short-term postoperative period.
