Background: Pediatric Anterior Cruciate Ligament reconstruction (ACLR) has increased over the past several years. In general, a graft size of 8mm is the accepted minimal size for adult ACLR, since literature suggests higher revision rates with grafts <8mm. Reproducing the native ACL size parameters would ideally inform graft size in pediatric patients, however, there is limited literature on the appropriate graft size in this population. If ACL size could be accurately estimated based on preoperative imaging, it may be possible to individualize ACL graft size to each patient. Purpose: To establish a correlation between the ACL and PCL size in normal pediatric knees, with the goal of informing appropriate graft size for ACL reconstruction. Methods: Normal knee MRIs of 200 females and 200 males ages 13-18 were assessed. …
