目的：探讨膝骨性关节炎患者与正常人行走过程中下肢生物力学参数的差异。方法：通过三维步态分析系统评价15例单侧膝骨性关节炎患者（患者组）及15例正常人（对照组）的步态时空参数、运动学及动力学指标。结果：患者组步速、步幅、步长、单支持相显著低于正常值（P<0.05），步宽、双支撑相、总支撑相显著高于正常值（P<0.05）；患者组支撑相平均屈膝角度、支撑相最大屈膝角度、摆动相最大屈膝角度、关节运动范围与对照组比较均有显著性差异（P<0.05）；患者组单足支撑结束时膝关节内部外展/内收力矩较对照组明显增加（P<0.05）。结论：膝骨性关节炎患者步态发生变化，步行过程中膝关节所受的压力明显高于正常人。

Objective:To investigate the differences of lower limbs biomechanical parameters in the process of walking between knee osteoarthritis and average person. Methods:According to three-dimensional gait analysis system the gait spatio-temporal parameters, kinematics and dynamics in-dex between 15 patients with unilateral knee osteoarthritis (patient group) and 15 cases of average person (control group) were evaluated. Results:The step speed, stride length, step length and single support phase of patient group were all significantly lower than normal value (P<0.05), step width, double support phase and total support phase were significantly higher than normal value (P<0.05);there was significant difference in average and maximum knee flexion angle of support phase, maximum knee flexion angle of swing phase and range of joint movement between patient group and control groups (P<0.05);knee joint internal abduction/adduction torque at the end of single foot support in patients group increased significantly comparing with control group (P<0.05). Conclusion:Gait of patients with knee osteoarthritis changes, whose pressure of knee joints in the process of walking is significantly higher than that of average person.
