目的 比较全膝关节置换(TKA)术中采用旋转平台型假体与固定平台型假体治疗膝关节病的疗效.方法 将90例行TKA的膝关节病患者分成两组,观察组(45例)采用旋转平台型假体,对照组(45例)采用后稳定固定平台型假体.比较两组患者的疗效.结果 两组患者术后1、6、12个月的膝关节评分、膝关节屈曲度、关节活动度都明显高于术前,差异均有统计学意义(P<0.05);两组术后各时段的各项指标评分比较差异均无统计学意义(P>0.05).治疗总有效率观察组为97.78%,高于对照组的93.33%,但差异无统计学意义(P>0.05).并发症发生率两组比较差异无统计学意义(P>0.05).结论 TKA术中应用旋转平台型假体与固定平台型假体治疗膝关节病均能获得很好的疗效,而前者疗效更好.%Objective To compare the clinical effects of rotating platform prosthesis and fixed platform prosthesis in total knee arthroplasty (TKA) in the treatment of knee arthropathy.Methods The 90 patients with knee arthropathy received TKA treatment were divided into two groups.Rotating platform prosthesis was applied to the observation group (45 cases),while posterior stabilized fixed platform prosthesis was applied to the control group (45 cases).And the clinical effects of patients in the two groups were compared.Results The knee score,knee flexion and joint mobility of the two groups at 1,6 and 12 months after operation were obviously better than those before operation,and the differences were statistical significance (P<0.05).The comparison of the indicators between the two groups after operation had no statistical significance (P>0.05).The total effective rate of observation group (97.78%) was higher than that of the control group (93.33%),but the difference had no statistical significance (P>0.05).The difference of the complications incidence rate between the two groups had no statistical significance (P>0.05).Conclusions Both rotating platform prosthesis and fixed platform prosthesis applied during TKA in the treatment of knee arthropathy have good clinical effects,and clinical effects of the former is better.
