Recurrent primary graft failure was experienced in 9% of patients, and 11.1% sustained a contralateral ACL tear. The median time to postoperative graft failure was 14 months (interquartile range, 9-41.5 months). Patients with a secondary ACL injury (eg, graft failure or contralateral ACL injury) were younger than those who did not sustain a subsequent injury (mean age, 15.7 \u00b1 1.8 years [graft failure] and 15.5 \u00b1 1.3 [contralateral ACL injury] vs 16.2 \u00b1 1.5 years, respectively;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .007). Survival analysis demonstrated that younger age at primary ACLR and earlier time to return to sport (RTS) were significantly associated with an increased rate of secondary ACL injury (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .05). With respect to combined secondary ACL injuries, as age at primary ACLR increases by 1 year, the rate of secondary ACL injury decreases by 27%. Similarly, for every subsequent 1-month delay in RTS, the risk of secondary ACL injury decreased by 13%.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Younger age and earlier time to RTS after ACL injury are independent risk factors associated with sustaining both primary ACL recurrent tear and contralateral ACL injury in the adolescent patient population.
