The supramalleolar osteotomy (SMO) is a joint-preserving surgical procedure that allows realignment of the ankle joint in severe deformity secondary to arthritis. This osteotomy realigns the mechanical axis to provide better weight distribution through the ankle joint. With an aligned mechanical axis, the overloaded asymmetric ankle joint will shift toward the preserved joint area in a valgus or varus ankle joint. The SMO also can be used via a staged approach to correct severe deformity in an end-stage arthritic ankle before total ankle arthroplasty to optimize the implant's longevity and improve overall functional outcomes.
距下关节外骨切开术（SMO）是一种保留关节的手术方法，可在关节炎引起的严重畸形时重新排列踝关节。这种骨切开术可重新排列力学轴线，通过踝关节更好地分布体重。在力学轴对齐的情况下，负荷过重的非对称踝关节将在踝内翻或外翻关节中向保留的关节区域移位。SMO 还可以通过分期方法用于在全踝关节置换术之前纠正晚期关节炎踝关节的严重畸形，以优化植入物的使用寿命并改善整体功能结果。
