Background: Despite reduced graft failure rates reported in randomized controlled trials comparing anterior cruciate ligament reconstruction (ACL-R) with and without lateral extra-articular tenodesis (LET), the impact of LET on postoperative patient-reported outcomes (PROs) remains poorly defined. Purpose: To compare short-term PROs, as well as anterior cruciate ligament (ACL) revision rates and clinical failure rates (defined as Knee injury and Osteoarthritis Outcome Score KOOS Quality of Life QoL value .5). Both groups demonstrated significant within-group improvements in KOOS 4 scores from baseline through the 2-year follow-up (all P ≤ .002). ACL revision rates at 2 years were 2.3% and 2.4% in the ACL-R + LET and ACL-R groups, respectively. Rates of clinical failure at 2 years were similar between groups (25.5% for ACL-R + LET vs 25.6% for ACL-R; P > .99). Conclusion: In this matched-cohort registry study, the addition of LET to primary ACL-R did not demonstrate superior short-term PROs at 1 or 2 years postsurgery.
