Conversion of knee arthrodesis to total knee arthroplasty is a difficult procedure accompanied by many complications due to soft tissue and extensor mechanism contracture and bone defects. We report two cases of distal femur osteosarcoma that had been undergone wide resection arthrodesis initially. Arthrodesis was converted to total knee arthroplasty with hinged prosthesis after many years. We describe patients' history and outline their surgical therapy and prognosis. To the best of the authors' knowledge, few cases have been previously reported in the literature.
将膝关节融合术转换为全膝关节置换术是一项困难的手术，由于软组织和伸肌机制挛缩以及骨缺损，会伴随许多并发症。我们报告两例最初接受了广泛切除关节融合术的股骨远端骨肉瘤病例。多年后，关节融合术被转换为使用铰链式假体的全膝关节置换术。我们描述了患者的病史，概述了他们的手术治疗和预后。据作者所知，此前文献中鲜有此类病例报道。
