全膝关节初次表面置换术治疗骨关节病(附52例随访疗效分析)

Clinical features and outcomes of osteoarthritis treated with primary total knee replacement:with analysis of 52 cases

目的(1)报告本院全膝关节初次表面置换术治疗骨关节病的临床特点和疗效。(2)探讨影响本院全膝关节初次表面置换术治疗骨关节病疗效的因素,为今后的临床工作提供经验与教训。方法对52例全膝关节初次表面置换术进行随访,并用HSS评分系统进行分析,随访3～110个月,平均28.3个月。结果手术优良率88.5%。病人术后在疼痛、功能及活动度等方面均有改善,尤其在缓解疼痛方面效果明显,但在关节活动度方面改善最少,有些甚至下降。结论全膝关节初次表面置换术是治疗严重膝关节骨关节病的有效手段;局部早期的并发症是影响本院全膝关节初次表面置换术近期疗效的主要因素。

Objective:(1) To report the special clinical features and outcomes of osteoarthritis treated with primary total knee replacement (pTKR)in the hospital.(2) To evaluate the factors that influence the outcomes of osteoarthritis treated with pTKR. Method: Follow-up study was carried out for 3 months to 110 months,averaged ~28.3 months, in 52 cases which were treated by total knee replacement, and the data were analyzed by HSS score system. Result: The follow-up showed that excellent and good results were achieved in 88.5%.The patients' pain, function and the rang of joint's movement (ROM) were improved respectively after operntion, especially, their pain was alleviated remarkably. However,the ROM had not been improved significantly in these patients,and some patients' ROM were decreased.Conclusion:The pTKR is an effective method for serious osteoarthritis;early local complications are the main factors influencing the early outcomes of pTKR.
