髌骨脱位是全膝关节置换术（TKA）后公认的主要并发症。这种损伤的治疗是根据脱位的原因来确定的。特别是，如果髌骨不稳定不是由假体错位引起的，近端重新对准、远端重新对准和外侧支持带松解都是可选择的。在此我们报告一例全膝关节置换术后髌骨脱位，由于内侧结构断裂，通过内侧髌股韧带重建和外侧支持带松解治疗。此外，我们提供了相关文献的简要回顾。
Patellar dislocation is a well-recognized major complication after total knee arthroplasty (TKA). Treatment of this injury is determined according to the cause of the dislocation. In particular, proximal realignment, distal realignment, and lateral retinaculum release are options if patellar instability is not caused by prosthetic malposition. Here we report a case of patellar dislocation following TKA due to rupture of the medial structures that was treated by medial patellofemoral ligament reconstruction and lateral retinacular release. In addition, we provide a brief review of the related literature.
