To evaluate the midterm clinical outcome, functional outcome, associated complications, and survivorship of high-flexion posterior-stabilized rotating-platform total knee arthroplasty.
We prospectively analyzed 701 knees in 501 patients, who underwent total knee arthroplasty using high-flexion posterior-stabilized rotating-platform prosthesis. Patients were assessed preoperatively and postoperatively for their ability to kneel, do full squats, do half squats, and sit cross-legged by using a patient-administered questionnaire.
Significant improvement was seen in patient-reported outcomes at the mean follow-up of 5.5 (range, 5-7) years. Mean flexion achieved postoperatively was 135° (range, 120°-150°) from a mean preoperative flexion of 108.8° (range, 90°-120°). Ninety-five percent of patients were able to sit cross-legged, 90% were able to kneel, 70% were able to perform a half squat, and 20% were able to perform a full squat.
Posterior-stabilized, rotating-platform, high-flexion design provides good postoperative flexion, functional outcome, and good midterm survivorship.
评估高屈曲后稳定旋转平台全膝关节置换术的中期临床疗效、功能结果、相关并发症及假体生存率。
我们前瞻性分析了501例患者的701个膝关节，这些患者接受了使用高屈曲后稳定旋转平台假体的全膝关节置换术。通过患者自行填写的问卷，对患者术前和术后的跪、全蹲、半蹲及盘腿坐能力进行评估。
在平均随访5.5年（范围5 - 7年）时，患者报告的结果有显著改善。术后平均屈曲角度从术前平均108.8°（范围90° - 120°）达到135°（范围120° - 150°）。95%的患者能够盘腿坐，90%的患者能够跪，70%的患者能够半蹲，20%的患者能够全蹲。
后稳定、旋转平台、高屈曲设计提供了良好的术后屈曲度、功能结果及良好的中期假体生存率。
