Although the knee is a common location, a ganglion cyst arising from the proximal tibio-fibular joint (PTFJ) is relatively rarer. Unique diagnostic and management difficulties are encountered as these can extend into subcutaneous tissue, or spread along peroneal muscles and nerve, or erode adjacent bone. We report here a PTFJ ganglion cyst which was indolent for at least 12 years and then caused destructive and expansile changes in the fibula over a period of 6 years after a total knee arthroplasty (TKA), simulating a malignancy. Although no wear or foreign body reaction could be shown, this alarming progression of a PTFJ ganglion cyst in the fibula after the TKA is a noteworthy association, and has not been recognized and reported before. Awareness of such a lesion can aid in the diagnosis and prevent unnecessary aggressive management.
尽管膝关节是常见的发病部位，但起源于胫腓近端关节（PTFJ）的腱鞘囊肿相对少见。由于这些囊肿可延伸至皮下组织，或沿腓骨肌和神经扩散，或侵蚀相邻骨骼，因此在诊断和治疗上存在独特的困难。我们在此报告一例PTFJ腱鞘囊肿，它至少12年无症状，在全膝关节置换术（TKA）后6年，导致腓骨出现破坏性和膨胀性改变，类似恶性肿瘤。尽管未发现磨损或异物反应，但TKA后PTFJ腱鞘囊肿在腓骨出现这种惊人的进展是一个值得关注的关联，此前尚未被认识和报道。认识到这种病变有助于诊断，并防止不必要的积极治疗。
