Background: The incidence of anterior cruciate ligament (ACL) reconstruction (ACLR) in children and adolescents has increased significantly, and many such patients are at increased risk for ACL retear. Lateral extra-articular tenodesis (LET) may be performed in conjunction with ACLR to reduce the risk of ACL retear. Purpose: To evaluate the 2-year clinical outcomes of ACLR with soft tissue quadriceps tendon (QUAD) autograft performed with a concomitant LET using a modified Lemaire technique in skeletally immature patients. Study Design: Case series; Level of evidence, 4. Methods: A consecutive series of adolescent patients who underwent QUAD autograft ACLR and LET with a minimum of 2 years of follow-up data were analyzed retrospectively. ACLR techniques, including all-epiphyseal and complete transphyseal, were indicated based on skeletal age. Outcome measures included return to sports, concomitant or subsequent surgical procedures, and multiple patient-reported outcome measures, including Single Assessment Numeric Evaluation (SANE), Pediatric International Knee Documentation Committee (Pedi-IKDC), and Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS) scores. Results: The final cohort included 49 consecutive adolescent patients aged 11 to 16 years (mean, 14.2 ± 1 years) with a minimum follow-up of 2 years. One patient was lost to follow-up. Of the patients included in the study (N = 48; 27 male, 21 female), 98% participated in high-risk competitive sports. Two (4%) patients were undergoing revision ACLR. Thirty-eight (79%) patients underwent complete transphyseal, and 10 (21%) patients underwent all-epiphyseal ACLR. Sixteen (33%) patients had subsequent surgical procedures, including 5 contralateral ACLR, 4 meniscal surgery, 4 QUAD autograft scar revision, 4 irrigation and debridement (2 patients, 2 each), and 3 hardware removal (2 for hemi-epiphysiodesis and 1 tibial socket button removal) procedures. The rate of graft rupture was 0%. At a mean follow-up of 3.4 ± 1.2 years ...
