Methods: In this retrospective study, 89 elite adolescent athletes who underwent either SB or DB ACL reconstruction were included. All patients were then divided into two groups: group 1 including 51 patients with SB ACL reconstruction (31 male, 20 femalemean age = 15.4 +/- 1.03 years) and group 2 including 38 patients with DB ACL (30 male, 8 femalemean age = 15.7 +/- 1.3 years). Clinical data were obtained, comprising skeletal maturity, sports type, ACL reconstruction technique, Lachman scores, KT-1000 (TM) arthrometer measurement, additional meniscal procedures as well as International Knee Documentation Committee (IKDC) score, Cincinnati score, and graft size. Results: The mean follow-up period was 53.1 +/- 8.6 months in group 1 and 46.4 +/- 9.1 months in group 2 (P = 0.61). The type of ACL reconstruction technique (SB or DB), gender, skeletal maturity, sports type, additional meniscal procedures and Lachman scores were not associated with the re-rupture of the ACL (P > 0.05). Moreover, ACL reconstruction technique did not effect the rate of re-rupture of an ACL. There were 21 re-ruptures (23.5\%) and 11 (12.3\%) contralateral ACL ruptures in total. Among 21 re-ruptures, 12 of them were in the DB group while nine of them in the SB group (P > 0.05). The groups did not differ with respect to age, the injured side, the time from injury to surgery, the postoperative follow-up time, or the preoperative physical examination results KT-1000 device (SSD), Cincinnati score, IKDC objective and subjective score,Lachman test and pivot-shift test). Conclusion: There are no differences in the re-rupture of an ACL, patient reported outcomes, and complications in adolescent elite players, when either an SB or DB technique is performed.Elite athletesAdolescent ACL reconstructionACL reconstruction failureSingle bundleDouble bundleArticleWOS:000767118100005
