退役运动员中-重度膝关节炎的治疗对策：保守治疗还是关节镜手术

 退役运动员膝关节炎（KOA）的治疗具有特殊性。为比较膝关节镜手术与保守治疗对退役运动员中-重度KOA的疗效及预后，采用了前瞻性队列研究的方法，比较了关节镜组与保守治疗组2年随访时的各项指标。结果显示，关节镜组伸膝受限角度、再次手术率显著低于保守组，而其关节活动度、Lysholm功能评分显著高于保守组，两组对疼痛改善程度未见差异。对于不适于行关节置换的退役运动员而言，关节镜手术的治疗中-重度KOA的中期疗效和预后优于保守治疗。

The treatment of moderate to severe knee arthritis for retired athletes: Conservative treatment or arthroscopic surgery

The treatment of knee arthritis (KOA) for retired athletes has its special problems. This paper compares the efficacy and the prognosis of the knee arthroscopy and the conservative treatment of moderate and severe KOA for retired athletes. A prospective cohort study is designed, and a series of parameters from the two groups at 2 year's follow-up are compared. The results show that for the arthroscopic group, significant lower knee flexion contracture angle and reoperation rate are observed than for the conservative group, while the joint range of motion, and the Lysholm score are significantly higher than those for the conservative group, and there is no difference in the pain improvement between the two groups. For retired athletes with moderate to severe KOA, the arthroscopic surgery has better medium-term efficacy and outcome than the conservative treatment.
