Abstract: linear regression.Results: Ninety-three patients (44 patients in ACLR group, mean age (ÆSD) 19.2Æ3.2 years, 54.5% females, and 49 patients in ACLR+LET group, 18.9Æ3.2years, 61.2% females) were included.Groups were prognostically balanced.We observed no significant difference in ACL SNQ between ACLR and ACLR+LET groups (mean difference [95%CI] ¼ -1.2 units [-0.3; 2.8], p>0.1).There was a significant relationship between tibial tunnel malposition and ACL SNQ, suggesting patients with malposition had poorer graft maturity (R¼0.30,p¼0.004).Increased SNQ was also negatively associated with Blumensaat angle (R¼-0.26,p¼0.01), hamstring strength limb asymmetry (R ¼-0.22,p¼0.04), and ACL-QoL (R¼-0.25,p¼0.02).We also observed significant positive relationships between ACL SNQ and lateral posterior tibial offset (R¼0.22,p¼0.03).Conclusion: There was no difference in graft maturation between knees undergoing ACL reconstruction with hamstring tendon autograft with or without LET at 2 years post-operative MRI analysis.When evaluating the entire sample, tibial tunnel malposition, lateral posterior tibial offset, anatomical impingement, hamstring strength weakness, and poorer ACL-QOL scores were significantly associated with higher graft SNQ.This study suggests that while some anatomical, surgical, and functional factors influence ACL graft maturation, the rotational stability gained from LET does not compromise the ACL graft.
