Demographic and injury-related data and KOOS subscales before ACLR and at the 1 and 2 years follow-ups were obtained. A survey to assess sport-specific outcomes and RTS was sent to eligible patients. Group comparisons were performed between the most popular sports and between females and males.<h4>Results</h4>Overall, 1392 patients with a mean age of 16.4±1.4 years at ACLR were included. The mean time between ACLR and survey completion was 9.7±4.2 years. The most prevalent type of sport was soccer, followed by handball, floor hockey/field hockey, basketball and other sports. Concomitant injuries (71%) and second ACL injuries (30%; 20% ipsilateral, 13% contralateral) were common across all sports. No significant differences were found in ipsilateral second ACL injuries across sexes and sports. 24% of patients competed at an elite level sport (highest national level of junior sport or higher) for some period after ACLR. 8% of patients did not RTS at all, with females significantly more often without RTS than males (9% vs 4%, p=0.041). Significant improvements were observed in KOOS subscales from baseline to the 1 and 2 years follow-ups for all sports.<h4>Conclusion</h4>Concomitant injuries are frequently observed after ACL injury in adolescents, with nearly one-third suffering a second ACL injury.
