Failed total ankle replacement is a complex problem that should only be treated by experienced foot and ankle surgeons. Significant bone loss can preclude revision total ankle replacement and obligate revision though a complex tibio-talo-calcaneal arthrodesis. A systematic review of the world literature reveals a nonunion rate of 24.2%. A weighted mean of modified American Orthopaedic Foot and Ankle Society Ankle and Hindfoot Scale demonstrated fair patient outcomes of 58.1 points on an 86-point scale (67.6 points on a 100-point scale). Complications were observed in 38 of 62 (62.3%) patients reviewed, with the most common complication being nonunion.
全踝关节置换失败是一个复杂的问题，应该只由经验丰富的足踝外科医生来处理。严重的骨丢失可能会妨碍全踝关节置换翻修，而不得不通过复杂的胫距跟关节融合术进行翻修。对世界文献的系统回顾显示，不愈合率为24.2%。改良的美国矫形足踝协会踝关节与后足评分量表的加权平均值显示，患者的平均结果为86分制下的58.1分（100分制下的67.6分），结果尚可。在纳入回顾的62例患者中，有38例（62.3%）出现并发症，最常见的并发症是不愈合。
