Females less likely to heal from ACL injuries than males

October 18, 2023

Injuries of the anterior cruciate ligament (ACL), located in the knee, are typically thought to be caused by acute traumatic events, such as sudden twists. Led by Penn State researchers, new work analyzing an animal model of ACLs suggests that such injuries can also occur as a result of chronic overuse. But more importantly, the team said, females also are less able to heal from these microtraumas than males, which may explain why females are two to eight times more likely to tear their ACL ligaments than males.
