Sex differences in knee joint loading: Cross‐sectional study in geriatric population

ABSTRACT This study investigated sex differences in knee biomechanics and investigated determinants for difference in a geriatric population. Age‐matched healthy volunteers (42 males and 42 females, average age 65 years) without knee OA were included in the study. Subjects underwent physical examina...

Description
Summary:ABSTRACT This study investigated sex differences in knee biomechanics and investigated determinants for difference in a geriatric population. Age‐matched healthy volunteers (42 males and 42 females, average age 65 years) without knee OA were included in the study. Subjects underwent physical examination on their knee and standing full‐limb radiography for anthropometric measurements. Linear, kinetic, and kinematic parameters were compared using a three‐dimensional, 12‐camera motion capture system. Gait parameters were evaluated and determinants for sex difference were evaluated with multiple regression analysis. Females had a higher peak knee adduction moment (KAM) during gait (p = 0.004). Females had relatively wider pelvis and narrower step width (both p
