Pediatrics Academy Offers Clinical Guide for ACL Injuries
By the Editors
A guide from the American Academy of Pediatrics focuses on injuries of the anterior cruciate ligament, including diagnosis, treatment, and prevention.
The document, available for free in Pediatrics, shows that girls are especially vulnerable to these injuries and are more prone to suffer them at a younger age than boys. ACL injury, regardless of the treatment used, predisposes the patient to degenerative arthritis of the knee. However, neuromuscular training — particularly repetitive jumping exercises to strengthen the lower extremity — can greatly reduce injury risks.
