Outcomes of All-Inside Arthroscopic ACL Reconstruction with Lateral Extra-Articular Tenodesis (ACLR + LET)

Background Anatomic single-bundle ACL reconstruction (ACLR) produces good results when the graft and tunnel are positioned in the anatomic footprint on the femoral and tibial insertion sites in a more oblique orientation. The Anterolateral Complex of the knee and its biomechanical role in controlling rotational laxity, internal rotation, and pivot shift has led to adding adjunctive procedures like extra-articular augmentation and lateral extra-articular tenodesis (LET) to decrease rotational laxity. We prospectively analyzed young adults with rotational instability and generalized laxity undergoing an arthroscopic single bundle ACLR with an additional LET procedure. Methods 42 patients, aged between 20 and 50, undergoing all-inside ACLR augmented with concomitant lateral extra-articular tenodesis between November 2020 and October 2021 were included. All patients were followed up for one year and functional assessment comprised of the International Knee Documentation Committee [IKDC] score, visual analogue score [VAS], and Lysholm Knee Scoring Scale at 6 months and 1 year. Return to activity was assessed using the Tegner Activity Score. Results The Lysholm score, IKDC score, and VAS showed significant improvements at 6 months after ACLR + LET ( p
