Fourteen failed aseptic-hinge total-knee arthroplasties (TKA) were reviewed to determine if an unlinked metal to plastic Total Condylar III type prosthesis can be used for salvage procedure. The overall preoperative Hospital for Special Surgery knee-rating score was 58 and improved to 81 post-operatively. The average postrevision range of motion was 83 degrees. The soft tissue sleeve, the built-in constraint of the prosthesis, and the restoration of the bone deficiency provided good stability, despite the loss of the collateral and cruciate ligaments. Radiolucent lines, less than 1 mm in width and incomplete, appeared in four femoral and ten tibial bone-cement interfaces. In one femoral component there was a 2-mm radiolucency with a cement fracture at the femoral stem tip. There were no failures or repeated revisions, but two knees required postoperative manipulation to improve motion. Total Condylar III type prosthesis can be satisfactorily used to salvage failed hinge TKA.
回顾了14例无菌铰链式全膝关节置换术（TKA）失败的病例，以确定非连接式金属对塑料全髁III型假体是否可用于挽救手术。术前特殊外科医院膝关节评分总体为58分，术后提高到81分。翻修术后平均活动范围为83度。尽管侧副韧带和交叉韧带缺失，但软组织套、假体的内置限制以及骨缺损的修复提供了良好的稳定性。在四个股骨和十个胫骨骨水泥界面出现了宽度小于1毫米且不完整的透光线。在一个股骨组件中，在股骨干末端有一条2毫米的透光线，伴有骨水泥骨折。没有失败或再次翻修的情况，但有两个膝关节需要术后手法治疗以改善活动度。全髁III型假体可令人满意地用于挽救失败的铰链式TKA。
