Marked varus or valgus hindfoot deformities in 3 patients with ankle osteoarthritis or rheumatoid arthritis were treated by corrective surgery using total ankle arthroplasty or distal tibia oblique osteotomy. All cases achieved not only sufficient correction and satisfactory clinical/radiographic hindfoot improvement but also improvements in both knee alignment and function.
Corrective surgery for hindfoot deformity can potentially change or improve ipsilateral knee alignment and function, representing an unexpected benefit of hindfoot realignment.
3 例踝关节炎或类风湿性关节炎患者出现明显的内翻或外翻后足畸形，通过全踝关节置换术或胫骨远端斜行截骨术进行矫正手术治疗。所有病例不仅获得了充分的矫正和满意的临床/影像学后足改善，而且膝关节对线和功能也得到了改善。
后足畸形的矫正手术可能会改变或改善同侧膝关节的对线和功能，这代表了后足重新对线的意外获益。
