Osteoarthritis of the knee is seen more frequently in females than males. However, few studies have examined the interplay of gender, gait mechanics, pain, and disability in persons with osteoarthritis. This study examines the influence of anthropometrics, radiographic disease severity, pain, and disability on gender differences in gait mechanics in patients with knee osteoarthritis. Gait mechanics for 26 men and 30 women were collected using 3-D kinematics and kinetics. Women had a significantly lower knee adduction moment than men and a significantly higher stride frequency. Within female subjects, variations in gait mechanics were primarily explained by weight, BMI, pain, and disability. In males, variations in gait mechanics were primarily explained by age and disability.
膝关节骨关节炎在女性中比男性更为常见。然而，很少有研究探讨骨关节炎患者中性别、步态力学、疼痛和残疾之间的相互作用。本研究考察了人体测量学、影像学疾病严重程度、疼痛和残疾对膝关节骨关节炎患者步态力学性别差异的影响。使用三维运动学和动力学收集了26名男性和30名女性的步态力学数据。女性的膝关节内收力矩明显低于男性，步频明显高于男性。在女性受试者中，步态力学的变化主要由体重、体重指数、疼痛和残疾来解释。在男性中，步态力学的变化主要由年龄和残疾来解释。
