Disruption of the extensor mechanism after total knee arthroplasty (TKA) is a devastating complication, usually requiring surgical repair. Although suture anchor fixation is well described for repair of the ruptured native knee quadriceps tendon, no study has discussed the use of suture anchors in quadriceps repair after TKA. We present an illustrative case of successful suture anchor fixation of the quadriceps mechanism after TKA. The procedure has been performed in a total of 3 patients. A surgical technique and brief review of the literature follows. Suture anchor fixation of the quadriceps tendon is a viable option in the setting of rupture after TKA.
全膝关节置换术后伸肌机制中断是一种破坏性的并发症，通常需要手术修复。虽然缝线锚钉固定术已广泛应用于修复原发性膝关节股四头肌肌腱断裂，但尚无研究探讨缝线锚钉在 TKA 后股四头肌修复中的应用。我们报告了 TKA 后成功应用缝线锚钉固定股四头肌机制的病例。该手术共在 3 例患者中进行。以下是手术技术和文献复习的简要介绍。缝线锚钉固定股四头肌肌腱是 TKA 后断裂的可行选择。
