Periprosthetic knee fractures and their complications are expected to increase as the numbers of knee arthroplasties continue to rise. We report our experience with revision knee arthroplasty for failure of primary fracture treatment. Five periprosthetic knee non-unions and 1 mal-union in 6 patients, with ages ranging from 65 to 83years (average 74.6years) were treated with revision total knee arthroplasty, and were followed up for 3 to 10years (average 4.5years). Union occurred in 8 to 18weeks (average 12.5weeks). All patients were ambulatory at the latest follow-up, with a range of motion averaging 84.2° (P = 0.03), and an Oxford Knee Score averaging 35 (P = 0.03). We conclude that union complications of periprosthetic knee fractures can be satisfactorily addressed with revision arthroplasty.
随着膝关节置换手术数量的持续增加，预计假体周围膝关节骨折及其并发症的数量将会增加。我们报告了我们在初次骨折治疗失败后进行膝关节翻修手术的经验。6 名患者中有 5 例假体周围膝关节骨不连和 1 例畸形愈合，年龄 65 岁至 83 岁（平均 74.6 岁），采用膝关节翻修全膝关节置换术治疗，随访 3 至 10 年（平均 4.5 年）。骨愈合时间为 8 至 18 周（平均 12.5 周）。所有患者在末次随访时均可活动，平均活动度为 84.2°（P=0.03），牛津膝关节评分平均为 35 分（P=0.03）。我们得出结论，假体周围膝关节骨折的愈合并发症可以通过翻修手术得到满意的解决。
