Fifty females with secondary hip OA were participated. The minimum joint space width (mJSW) of the hip as a degenerative sign and Sharp and center edge (CE) angles as morphological variables were measured radiographically. Hip joint pain was assessed using a visual analog scale. As gait variables, walking speed, range of hip motion, hip moment peak, and hip moment impulse were calculated. Daily cumulative hip loading was calculated as the hip moment impulse multiplied by the mean number of steps per day. After bivariate correlation analyses between dependent (mJSW and pain) and independent variables (age, body mass index, sharp\/CE angles, steps per day, and gait variables), separate forward\u2010backward stepwise multiple regression analyses were performed for each dependent variable. Daily cumulative hip loading in the sagittal plane (<jats:italic>\u03b2<\/jats:italic>\u2009=\u20090.30, <jats:italic>p<\/jats:italic>\u2009=\u20090.021) and age (<jats:italic>\u03b2<\/jats:italic>\u2009=\u2009\u22120.36, <jats:italic>p<\/jats:italic>\u2009=\u20090.007) were significantly associated with the mJSW. Walking speed (<jats:italic>\u03b2<\/jats:italic>\u2009=\u2009\u22120.36, <jats:italic>p<\/jats:italic>\u2009=\u20090.008) and age (<jats:italic>\u03b2\u2009<\/jats:italic>=\u20090.29, <jats:italic>p<\/jats:italic>\u2009=\u20090.031) were significantly associated with hip joint pain. Decrease in daily cumulative hip loading in the sagittal plane was associated with mJSW independently of age. Although the causal relationship was not clear, patients with hip OA reduced total exposure to hip joint loading adaptively rather than lowering the hip moment peak concerning worsening of hip degeneration. \u00a9 2016 Orthopaedic Research Society.
