Anterior cruciate ligament (ACL) injuries in children
and teens are less common than in adults. But they do occur, especially in
teens. An injury that hasn't been treated (or one in which the treatment didn't work) can lead to future knee problems. The knee may become more and more unstable. Over time,
osteoarthritis may develop.

teen is to full growth, the lower the risk of these problems.
Rest after surgery and a
long rehab program are very important.
