不同关节病理程度的膝关节骨关节炎的肌肉软弱程度比较

The comparison of the extent of arthrogenous muscle weakness between knee osteoarthritic patients with different extent of joint pathology

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。

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.
