چکیده انگلیسی
Changes in PTS moderately affected muscle forces and joint contact forces at mid-stance period. Both active (at mid-stance) and passive (at all flexion angles) models showed a substantial increase in the anterior tibial translation and ACL force as PTS increased with reverse trends as PTS decreased. In the active model of gait at mid-stance, ACL force increased by 75% (from 181Â N to 317Â N) in steeper PTS but decreased by 44% (to 102Â N) in flatter PTS. The posterolateral bundle of ACL carried the load at smaller flexion angles with a shift to its anteromedial bundle as flexion increased. In accordance with earlier imaging studies, greater PTS is a major risk factor for ACL rupture especially in activities involving large compression forces.
