摘要

Cine phase contrast MRI, combined with a model-based rigid body tracking technique, was used to measure kinematics during a knee extension exercise in both knees of 16 anterior cruciate ligament (ACL) deficient surgical candidates and 16 uninjured subjects. A statistically significant increase in anterior tibial translation was observed in the ACL-deficient knees. Evidence of disruption to the screw-home mechanism was observed in the ACL-injured knees, although this was not a statistically significant result.
