1. 30% of adolescents who underwent anterior cruciate ligament (ACL) reconstruction experienced a second injury within 10 years.
2. Soccer, handball, hockey, and basketball were the most common sports prior to injury.
3. Most adolescents also had additional knee damage at the time of surgery, with high rates of meniscus and ligament injuries.
4. Knee function improved after surgery, but the risk of ongoing joint damage and reinjury remained significant.
5. 92% of adolescents returned to sport postsurgery, with 64-76% returning to their preinjury level of performance.
6. Elite-level competition declined following surgery.
7. Concomitant injuries occurring at the time of the ACL tear were frequent, with medial meniscus tears and lateral meniscus damage being common.
