Official title

Epidemiology of Jump-Landing Movements and ACL Injury

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The anterior cruciate ligament (ACL) is located inside the knee joint and provides stability to the knee. ACL injuries occur more frequently in women than men; the reason for this is unknown. The purpose of this study is to determine gender-specific anatomical, hormonal, and demographic risk factors for ACL injury. This observational cohort study will only enroll incoming cadets at the U.S. Naval, Air Force, or Military Academies. Study hypothesis: Human movement factors, including key kinetics and kinematics of the knee during a jump-landing task, are associated with the rate of ACL injury.
