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.
A child with
an ACL injury can sometimes be treated without surgery to avoid damage
to the child's still-developing bones. Your child can try rehab exercises, wearing a brace, and avoiding activities that require
jumping or twisting.
Surgery is usually recommended for active children, to keep the knee more stable and to help prevent future problems.
An avulsion fracture
is more common in young children. This happens when the ligament and a piece of bone separate from the rest of the bone. It can often be treated with a cast. But
it sometimes needs surgery.
You may consider surgery if:
The particular risk of surgery in a child whose bones
are still growing is slowed growth. This could make one
leg longer than the other. Other risks include a deformed thigh bone. The closer a child or
teen is to full growth, the lower the risk of these problems.
Rest after surgery and a
long rehab program are very important.
