摘　　要：目的观察高屈曲度全膝关节假体置换治疗膝骨关节病的疗效。方法 42例(52膝)采用高屈曲度假体进行膝关节置换,术后4、12周进行膝关节评分,测量活动度。结果术前平均膝关节屈曲度(92.6±11.3)°,KSS评分(41.6±4.9)分,功能评分(47.2±6.9)分。术后4周平均KSS评分(86.0±6.8)分,功能评分(83.6±7.8)分,膝关节活动度平均为(115.2±15.7)°;术后12周平均KSS评分(92.7±8.1)分,功能评分(91.5±10.4)分,膝关节活动度(132.0±11.4)°。结论高屈曲度全膝关节假体置换治疗膝骨性关节病近期疗效明显、确切,能够明显改善膝关节功能,减轻症状,获得比常规膝关节假体更大的活动度。Objective To observe the early result of deep flexion knee prosthesis for treatment of knee osetoarthritis. Methods Forty-two patients （52 knees） underwent primary total knee arthroplasty with deep flexion knee prostheses. Clinical results were evaluated preoperatively,4 and 12 weeks postoperatively using KSS scoring system, and the range of knee motion were measured. Results Before operation,the mean range of knee motion was （92.6±11.3）,KSS score was （41.6±4.9）,the value of the functional scores was （47.2±6.9）.Four weeks after operation, the mean value of the functional scores was （86.0±6.8）, KSS scores was （83.6±7.8）,the range of motion was（115.2±15.7）;Twelve weeks after operation,the mean value of the functional scores was （92.7±8.1） ,KSS scores was （91.5±10.4） ,the range of knee motion was（132.0±11.4）. Conclusion Deep flexion knee prosthesis is effective for treatment of knee osetoarthritis.
