Sagittal plane joint angles. The mean of individual time-normalized angles in the sagittal plane for male and female subjects with and without knee OA during stance phase and swing phase. All angles are measured in terms of the distal segment relative to the proximal segment. a Ankle plantarflexion and dorsiflexion, b knee flexion and extension, c hip extension and flexion, d foot dorsiflexion and plantarflexion with respect to ground, and e posterior tilt and anterior tilt of the pelvis
