Sixty-three failed total knee arthroplasties in 60 patients (27 females, 33 males; average age, 66 years) were treated consecutively with revision using cemented component fixation and an uncemented stem. Patients were followed for a mean of 5.75 years (range, 2-10 years); none were lost to follow-up. There were 12 (19%) re-revisions: 6 (10%) were revised for aseptic loosening, 4 (6%) for recurrent infection, and 2 (3%) for instability. Knee Society Pain Scores improved from 56 to 81, and function scores improved from 49 to 62 points. Latest radiographs in retained knees showed none with definite femoral loosening but 4 with tibial component loosening. Combining those revised for aseptic loosening and radiographic aseptic loosening, mechanical failure occurred in 10 patients (16%).
60例患者（27例女性，33例男性；平均年龄66岁）的63例全膝关节置换失败病例连续接受了使用骨水泥固定组件和非骨水泥柄的翻修治疗。患者平均随访5.75年（范围2 - 10年）；无一例失访。有12例（19%）再次翻修：6例（10%）因无菌性松动翻修，4例（6%）因反复感染翻修，2例（3%）因不稳定翻修。膝关节协会疼痛评分从56分提高到81分，功能评分从49分提高到62分。留存膝关节的最新X线片显示，无明确股骨松动病例，但有4例胫骨组件松动。将因无菌性松动翻修的病例与影像学无菌性松动病例合并计算，10例患者（16%）发生机械性失败。
