摘　　要：背景:高屈曲度固定平台膝关节假体与高屈曲度旋转平台膝关节假体设计机制不同,观点也各不相同。目的:通过对两种膝关节假体置换患者进行美国特种外科医院膝关节评分(HSS评分)及步态分析,比较两类假体置换患者的早期疗效。方法:随机选取人工膝关节置换患者34例,按照置换假体的不同分为高屈曲固定平台假体组和旋转平台假体组进行对比观察。结果与结论:两类不同设计假体在置换后12个月内在HSS评分及各步态参数差异无显著性意义。通过步态分析技术,能够更精确地对膝关节置换后参数进行比较,通过与临床评分结合,更全面地了解术后疗效。BACKGROUND：Because of different design mechanisms in fixed platform and rotating platform prosthesis,there are different opinions.OBJECTIVE：To compare the early gait parameters and HSS scores following total knee arthroplasty with fixed platform and rotating platform high-flexion prosthesis and to find the difference between two treatment methods.METHODS：Thirty-four knees in 34 patients with osteoarthritis undergoing total knee arthroplasty were evaluated by using HSS and gait analysis technique.The effects of total knee arthroplasty with fixed platform and rotating platform high-flexion prosthesis were compared.RESULTS AND CONCLUSION：By using HSS and gait analysis,we found no difference in two kinds of prostheses within 12 months following total knee arthroplasty.Through HSS and gait analysis technique,we can get more accurate and more comprehensive information.
