非骨水泥型踝关节置换术治疗踝关节骨性关节炎

目的 探讨非骨水泥型踝关节置换术治疗踝关节骨性关节炎的手术策略和临床疗效.方法 对18例(19踝)踝关节骨性关节炎患者行非骨水泥型踝关节置换术,平均随访时间为18.5(8-45)个月.对手术前后关节疼痛、活动度、关节功能改善进行对比研究,术后关节功能根据Kofoed评分进行评价.结果 所有患者术后临床症状及踝关节功能都有不同程度的改善.背伸活动度由术前平均8.8°,改善为术后平均18.6°；跖屈活动度由术前平均12.5°,改善为术后平均28.3°; Kofoed评分由术前平均42.2分,改善为术后平均80.7分.X线片分析未见假体松动及感染表现.结论 非骨水泥型踝关节置换术是治疗踝关节骨性关节炎的有效方法.

Non-cement total ankle replacement for osteoarthritis of ankle joint

Objective To study the surgical procedure and therapeutic effect of non-cement total ankle replacement for osteoarthritis of ankle joint.Methods Eighteen patients(19 ankle-joints) with osteoarthritis of ankle joint underwent non-cement total ankle replacement and were followed up for 18.5 months(range 8-45 months).Pain,motion and function of ankle joints were compared before and after operation.The function of ankle-joint was assessed with the Kofoed scoring system.Results The symptoms,signs and function of ankle-joint were improved in all patients after operation,with the extension,flexion and score of ankle-joint increased to 18.6°,28.3°,and 80.7 after operation from 8.8°,12.5°,and 42.2 before operation.No looseness and infection were found on X-ray film.Conclusion Non-cement total ankle replacement is an effective procedure for osteoarthritis of ankle joint.
