BACKGROUND: Joint-preserving, realignment surgical procedures have gained increasing popularity as treatment of asymmetric early- and mid-stage @entity3681 . The aim of the present study was to quantify bilateral gait biomechanics in @entity1 who underwent ankle realignment surgery by supramalleolar osteotomies. METHODS: Eight @entity1 , a minimum of 7 years after realignment surgery, and 8 healthy controls were included in this study. Three-dimensional instrumented gait analysis was used to assess spatiotemporal parameters, bilateral joint angles, and moments. Furthermore, a clinical evaluation on @entity158 , ankle function, and quality of life was performed. RESULTS: Compared with the healthy controls, the @entity1 walked more slowly, had a smaller sagittal hindfoot range of motion on their affected leg, and had a lower peak ankle dorsiflexion moment (P < .05). There were no significant differences compared with controls for the ranges of motion in the foot segments of the nonaffected foot and for the knee and @entity572 and peak moments of both legs. Additionally, @entity1 and controls did not differ in the quality of life score. However, in the @entity158 subscore, the @entity1 reported significantly more @entity158 than the healthy @entity1 . CONCLUSION: Despite different gait biomechanics of the affected foot after ankle realignment surgery, the quality of life for @entity1 was comparable to that of healthy controls. Therefore, supramalleolar osteotomies should be considered as a promising treatment option in @entity1 with asymmetric non-end-stage @entity3681 . LEVEL OF EVIDENCE: Prognostic level III, comparative study.
