Patients with varus or valgus hindfoot deformities usually present with asymmetric ankle osteoarthritis. In-vitro biomechanical studies have shown that varus or valgus hindfoot deformity may lead to altered load distribution in the tibiotalar joint which may result in medial (varus) or lateral (valgus) tibiotalar joint degeneration in the short or medium term. The treatment of asymmetric ankle osteoarthritis remains challenging, because more than half of the tibiotalar joint surface is usually preserved. Therefore, joint-sacrificing procedures like total ankle replacement or ankle arthrodesis may not be the most appropriate treatment options. The shortand midterm results following realignment surgery, are very promising with substantial pain relief and functional improvement observed post-operatively. In this review article we describe the indications, surgical techniques, and results from of realignment surgery of the ankle joint in the current literature.
患有内翻或外翻后足畸形的患者通常会出现踝关节不对称性骨关节炎。体外生物力学研究表明，内翻或外翻后足畸形可能导致距下关节的负荷分布发生改变，从而导致中短期的内（内翻）或外（外翻）侧距下关节退变。不对称性踝关节骨关节炎的治疗仍然具有挑战性，因为通常有超过一半的距下关节表面得到保留。因此，关节破坏性手术，如全踝关节置换术或踝关节融合术可能不是最合适的治疗选择。踝关节重新排列手术后的短期和中期结果非常有希望，术后观察到明显的疼痛缓解和功能改善。在这篇综述文章中，我们描述了目前文献中踝关节重新排列手术的适应证、手术技术和结果。
