Forty-eight revision total knee arthroplasties (TKAs) for failed unicompartmental total knee prostheses were evaluated at 5.4 +/- 2.5 years after revision. The most frequent mode of failure of the original arthroplasty was loosening. All revisions used a condylar-type prosthesis. Fifty percent of the knees had bone defects that were filled with cement. Good or excellent results were achieved in 81% of the knees. One knee had a complete radiolucent line adjacent to the tibia at last evaluation. The surgical complication rate was 13%. Predictable salvage of the failed unicompartmental TKA can be achieved by revision arthroplasty.
对48例因单髁全膝关节假体失败而进行翻修的全膝关节置换术（TKA）患者，在翻修术后5.4±2.5年进行了评估。原关节置换术最常见的失败模式是松动。所有翻修均使用髁型假体。50%的膝关节存在骨缺损，用骨水泥填充。81%的膝关节获得了良好或优秀的结果。在最后一次评估时，有1例膝关节在胫骨旁出现了完整的透亮线。手术并发症发生率为13%。通过翻修关节成形术可以实现对失败的单髁TKA进行可预测的挽救。
