对139例(男47例，女92例)膝关节骨性关节炎(OA)患者在水平行走、上楼梯和下楼梯过程中的膝关节运动学和动力学进行了测定。膝关节活动度在患者和正常人之间无显著差异。与正常受试者相比，膝骨性关节炎患者的膝关节内伸肌力矩显著减少。这一差异反映了患者对减轻膝关节负荷的补偿。此外，患有骨性关节炎且体重指数较高的受试者的膝关节伸展力矩较低。女性受试者的膝关节屈曲度和伸膝力矩显著增加。这种性别差异可能部分解释了女性骨性关节炎患病率上升的原因。大多数OA治疗的测试都是通过不反映功能活动的标准进行评估的。这项研究表明，客观的步态分析可以用于记录膝骨性关节炎患者使用的步态适应。(C)2001爱思唯尔科学有限公司。保留所有权利。
The knee kinematics and kinetics of 139 patients (47 males and 92 females) with Grade II knee osteoarthritis (OA) were measured during level walking, stair ascent and stair descent. There was no significant difference in knee motion between the patients and normal subjects. The patients with knee OA had a significantly reduced internal knee extensor moment compared to normal subjects. This difference reflects the patient's compensation to reduce the knee joint loading. Further, subjects with OA and a higher body mass index have a lower knee extensor moment. The female subjects had significantly greater knee flexion and a greater knee extensor moment. This gender difference may partially explain the increased prevalence of OA in females. Most tests of OA treatments are assessed by criteria that do not reflect functional activities. This study demonstrates that objective gait analysis can be used to document gait adaptations used by patients with knee OA. (C) 2001 Elsevier Science Ltd. All rights reserved.
