旋转平台膝关节假体在治疗膝关节病中的应用

目的：探讨旋转平台膝关节表面假体的特点，以及采用这种假体行人工膝关节置换治疗膝关节疾病的手术技巧和并发症的防治。方法：选择山东大学附属省立医院2005年1月到2009年1月施行的旋转平台人工膝关节置换病例62例（74膝）进行回顾性分析，采用HSS(hospital for special surgery)膝关节评分标准作手术前后比较。结果：术前HSS评分为34～58分，平均44.99分；术后随访3～48个月，平均22个月，HSS评分为69～98分，平均88.78分，优良率为98.39％。采用统计软件SPSS13.0分析，t=-107.66，P<0.01。62例患者术后疼痛缓解，功能明显改善，未发现感染和松动等并发症。结论：选用旋转平台膝关节表面假体行人工膝关节置换治疗膝关节病手术简便，术后恢复好，并发症少，短期临床效果满意。

The treatment of the knee arthropathy with rotating-platform knee prosthesis

[Objective] To study the features of rotating-platform knee prosthesis,the operative technique and the methods of preventing complications in the treatment of knee arthropathy with total knee arthroplasty. [Method] We retrospectively analyzed the data of the 62 patients (74 knees) who received the total knee arthroplasty using rotating-platform knee prosthesis in Provincial Hospital Affiliated To Shandong University from January 2005 to January 2009,.The clinical results of pre-operation and after-operation were evaluated by the HSS knee rating score system. [Result] The average HSS knee rating score was 44.99 (from 34 to 58) before total knee arthroplasty.The 62 patients (74 knees) were followed-up for the average time of 22 months (form 3 months to 48 months) after- operation.The average HSS knee rating score improved to 88.78(from 69 to 98),and the good-to-excellent rate was 98.39%.SPSS (virsion13.0) statistical software was used for analysis,t=-107.66,P<0.01.Pain and function of all the patients were obviously ameliorated after-operation and all the patients had no infection or prosthetic loosening. [Conclusion] Total knee arthroplasty using rotating-platform knee prosthesis owns advantages of easy surgical operation, less complications ,good recovery and satisfactory results in the near future.
