Loose joints may explain ACL injuries in girls

Young female athletes are known to be at greater risks for ACL injuries, and now researchers say they think they know why. They believe loose joints may be to blame. The anterior cruciate ligament, or ACL, is a tough band of tissue that runs from the thigh bone to shin bone.

This latest study found female athletes who's knee joints were less stable or were hyperextended were five times more likely to injure their ACL.

After puberty, joint flexibility tends to increase in females and decrease in males. Researchers are now investigating what type of exercises are most effective at lowering the risks.

The findings are published in the American Journal of Sports Medicine.
