Anterior cruciate ligament (ACL) tears have become an increasingly prevalent problem in pediatric patients due to increased youth sports participation and early sports specialization. A high index of suspicion should be utilized for any young patient with an acute knee injury and an associated effusion or difficulty bearing weight. A thorough work-up should be performed that includes a careful assessment of growth remaining and concomitant injuries. While nonoperative management may be a consideration for select cases, most patients will benefit from early surgical management. ACL deficiency or delayed reconstruction can lead to early chondral degeneration and risk for further injury to the cartilage and menisci. The goal of ACL reconstruction is to create a stable knee and prevent secondary chondral or meniscal injury. Physeal-sparing and physeal-respecting transphyseal techniques have been developed that allow for safe and successful ligament reconstruction while minimizing the risk of growth arrest. Younger patients have a higher risk of reinjury and require a longer recovery period for a full return to sports than their older counterparts. Even though there have been advances in the safe and successful treatment of ACL tears in pediatric patients, it remains a devastating physical and psychological injury, and increased efforts should be made at prevention. Injury prevention programs have been shown to reduce the risk of ACL tears, and it is important to increase awareness and utilization of prevention strategies.
