We present a case report of a patient with osteopetrosis and refractory bilateral knees osteoarthritis who underwent bilateral total knee arthroplasties (TKAs). After conservative management has failed, surgical treatment with arthroplasty is an excellent alternative with satisfactory outcomes. TKA in patients with osteopetrosis has only been described in 6 other case studies, none of which underwent bilateral TKA. To perform this procedure, additional attention should be directed toward the presurgical planning because of the amplified difficulty of the procedure and the altered bone biology that increases the risks of intraoperative fractures and markedly extends the time of surgery. This report describes a case of osteopetrosis with refractory osteoarthritis managed with bilateral TKA, the surgical technique and special considerations, complications, and future recommendations.
我们报告一例患有骨质石化症和难治性双侧膝关节骨关节炎的患者接受双侧全膝关节置换术（TKA）的病例。在保守治疗失败后，关节置换术的手术治疗是一种具有良好效果的极佳选择。骨质石化症患者的TKA仅在其他6项病例研究中有所描述，其中无一例接受双侧TKA。由于该手术难度增大以及骨生物学改变增加了术中骨折风险并显著延长手术时间，因此进行此手术时应格外关注术前规划。本报告描述了一例采用双侧TKA治疗的骨质石化症合并难治性骨关节炎病例、手术技术及特殊注意事项、并发症和未来建议。
