Total knee arthroplasty in neuropathic (Charcot) joints is technically demanding. Most studies report significant improvement in knee function, despite a high incidence of complications. We present a case of idiopathic, unilateral neuropathic arthropathy of the knee treated with a modular stemmed, constrained total knee arthroplasty. Unscrewing of the stem of the tibial component was detected a year following surgery. The tibial component was revised to a custom made monobloc stemmed implant. Satisfactory knee function was noted at short-term follow-up. This case highlights a potential problem of using modular long-stem implants in neuropathic joints and emphasises the need for close follow-up of these difficult cases.
在神经性（夏科氏）关节中进行全膝关节置换术对技术要求很高。大多数研究报告称，尽管并发症发生率很高，但膝关节功能仍有显著改善。我们报告一例采用模块化柄型、限制性全膝关节置换术治疗的特发性、单侧膝关节神经性关节病病例。术后一年发现胫骨部件的柄松动。胫骨部件被翻修为定制的一体式柄型植入物。短期随访时膝关节功能良好。该病例突出了在神经性关节中使用模块化长柄植入物的一个潜在问题，并强调了对这些疑难病例进行密切随访的必要性。
