Although heterotopic ossification (HO) after total hip arthroplasty has been very well described as a cause of disability, much less was written on clinical dysfunction of HO after total knee arthroplasty (TKA). To the extent of our knowledge, there has been no published case of complete bony ankylosis, secondary to severe generalized HO, after a TKA. We present the case of a 67-year-old female treated successfully, with surgical excision of ossification and TKA revision surgery, using a rotating hinge system.

尽管全髋关节置换术后的异位骨化（HO）作为致残原因已被详细描述，但关于全膝关节置换术（TKA）后HO的临床功能障碍的报道却少得多。就我们所知，尚无全膝关节置换术后因严重全身性HO继发完全性骨融合的病例报道。我们报告一例67岁女性患者，通过手术切除骨化组织并使用旋转铰链系统进行全膝关节置换翻修手术，成功治愈。
