摘要 目的:用等速技术比较有显著关节病理程度差异的原发性、症状性膝关节骨关节炎的肌肉软弱程度。方法:比较X线显示有明显软骨丧失的和无明显软骨丧失的膝骨关节炎的肌肉软弱的程度。在Cybex6000上,对12例有明显软骨丧失和21例无明显软骨丧失的单侧膝骨关节炎患者以60°/s、120°/s、180°/s等速测定并比较屈伸膝肌力参数的下降程度。结果:有明显软骨丧失和无明显软骨丧失的患肢屈伸膝肌群的等速肌力参数的下降程度无统计意义上的差别。结论:膝骨关节炎的肌肉软弱程度和关节病理程度不一定有关。 关键词 病理;软骨;关节源性肌肉萎缩;等速测试

Abstract Objective:To compare the extent of arthrogenous muscle weakness between knee osteoarthritic patients with different extent of joint pathology with isokinetic technique.Method:The muscle weakness extent between 12 unilateral knee OA patients with significant articular cartilage loses and 21 cases without significant articular cartilage loses under X-ray were compared.Result:There was no statistical difference in the decreasing extent of parameters of extensors and flexors between the patients with and without significant articular cartilage loses.Conclusion:There may be no relation between the extent of arthrogenous muscle weakness and the extent of joint pathology in knee osteoarthritic patients.

膝关节骨关节炎(osteoarthritis,OA)的关节病理表现在骨、软骨和滑膜上。为了显示病理程度的不同,常将X线显示有明显软骨丧失(即关节间隙狭窄)的患者和无明显软骨丧失(即关节间隙无明显狭窄)的患者区分开来。以往看来,较严重的关节病理级别往往表示预后欠佳。有作者认为,根据关节源性肌肉抑制(arthrogenous muscle inhibition,AMI)的严重与否也能在一定程度上判断预后。这就产生了一个问题,即关节病理和AMI或是关节源性肌肉软弱(arthrogenous muscle weakness,AMW)有无一致性,或两者有无相关。因以往文献缺乏这方面的报道,而这个问题又牵涉对膝OA严重程度的认识,我们做了以下的研究。
