Could a Parent's hamstring tendon rebuild a Child's torn ACL?

This trial is testing whether using a hamstring tendon from a parent can safely and effectively reconstruct a torn anterior cruciate ligament (ACL) in children and teenagers whose bones are still growing. The study will enroll 40 patients aged 8 to 17 with ACL tears that need surgery. The parent donates one of their hamstring tendons, which is then implanted into the child during arthroscopic knee surgery. Researchers will track knee function, symptoms, and ability to return to sports for up to two years after the procedure.
