目的 观察人工全踝关节置换术治疗踝关节骨关节炎的疗效.方法 对1999年10月- 2006年10月所收治的42例患有严重踝关节骨关节炎并符合手术适应证的患者进行人工全踝关节置换术.并按照Kofoed评分标准,对患者的疼痛程度、踝关节功能、踝关节活动度进行评分；同时根据Mayo踝关节置换的评价标准对患者进行疗效评价.结果 根据Kofoed评分标准,术后患者在疼痛、功能和活动度方面都明显优于术前(P＜0.05),优良率为90％ (28/31)；而根据Mayo踝关节置换的评价标准,优良率为87％ (27/31).结论 人工全踝置换术能有效缓解踝关节疼痛,改善踝关节活动度及功能,为需行踝关节融合术患者提供一种有效的方法.

Therapeutic effect of total ankle replacement for osteoarthritis of ankle joint

Objective To observe the efficacy of total ankle replacement in treatment of osteoarthritis of ankle joint.Methods Between October 1999 and October 2006,42 patients with ankle osteoarthritis were admitted in Beijing Jishuitan Hospital.All the patients met surgical indications and were performed total ankle replacement with S.T.A.R.system ( Scandinavian Total Ankle Replacement) (Waldemar Link,Hamburg,Germany).The pain in patients,motion and function of joint were evaluated pre- and post-operatively according to Kofoed scoring system,and the efficacy was evaluated with the Mayo'evaluation criteria of total ankle replacement.Results According to Kofoed scoring system,the postoperative situation was obviously superior to the preoperative in pain,motion and function of joint(P ＜ 0.05 ),and the excellent and good rate was 90.32％.While,the excellent and good rate was 87.5％with the Mayo' evaluation criteria of total ankle replacement.Conclusion Total ankle replacement,which can relieve pain,restore ankle function and improve ankle activity,provides another effective method for the patients who need ankle arthrodesis.
