摘  要:目的 随机对照试验比较固定平台型和旋转平台型假体在人工全膝关节置换术后的早期临床疗效.方法 将2008年1至10月新疆医科大学第一附属医院关节外科诊断为膝骨性关节炎的患者,连续随机分配至固定平台组和旋转平台组行全膝关节表面置换术,记录术前及术后6个月,1、2年时术膝的膝关节评分(KSS评分、HSS评分)、WOMAC骨关节炎评分、疼痛评分、功能评分以及膝关节最大屈曲度(ROM)等指标,进行统计学分析.结果 比较两组病人术前及术后6个月,1、2年时KSS膝评分P值分别为0.754、0.802、0.561、0.764,HSS评分P值分别为0.737、0.361、0.254、0.330,WOMAc骨关节炎评分P值分别为0.976、0.557、0.946、0.818,ROM随访P值分别为0.519、0.646、0.175、0.276,差异均无统计学意义.结论 固定平台型和旋转型膝假体TKA术后早期临床疗效差异无统计学意义.Objective To compare the early clinical outcomes of primary total knee arthroplasty by a fixed-bearing versus mobile-beating prosthesis.Methods A total of 80 patients with osteoarthritis at our hospital from January 2008 to October 2008 were sequentially and randomly assigned into Group A (fixedbearing prosthesis) (40 knees) and Group B (mobile-bearing prosthesis) (40 knees).And the data of the range of motion (ROM),Knee Society Score (KSS) and Western Ontario MacMaster (WOMAC) were collected at pre-operation and 6,12 and 24 months post-operation respectively.Results The P values were as follows:KSS:0.754,0.802,0.561,0.764;HSS (Hospital for Special Surgery):0.737,0.361,0.254,0.330;WOMAC (Western Ontario and McMaster Universities) osteoarthritis index :0.976,0.557,0.946,0.818;ROM follow-up:0.519,0.646,0.175,0.276.No significant differences were found in clinical outcomes between two groups.Conclusion The fixed-bearing and mobile-bearing prostheses show no difference in clinical outcomes.
