Lesões do Joelho associadas à Rotura do Ligamento Cruzado Anterior em População Pediátrica

Abstract

Our goal was to assess the type and frequency of injuries associated with torn anterior cruciate ligament (ACL) in the pediatric population, as well as to compare patterns of associated injuries between children/adolescents and adults. We included all children and adolescents undergoing ACL reconstruction at our institution between 2013-2019. We analyzed the type and frequency of knee injuries associated (meniscus, cartilage and collateral ligaments) with ACL tears. We included 84 adolescents, with a mean age of 15.9 years. In total, 69% had associated injuries, with meniscal injuries being the most frequent (66.7%). The lateral meniscus was more frequently involved than the medial (48.8% vs 35.7%). Chondral lesions were only detected in 6% of children/adolescents. In adults, unlike what was seen in adolescents, the association of ACL tear with medial meniscus injury is more frequent than in the lateral meniscus. It is concluded that the main knee injury associated with ACL tear in children and adolescents is indisputably the meniscal injury and that only a small part (31%) has isolated ACL injury.
