684 Lateral Extra-Articular Tenodesis Versus Anterolateral Ligament Reconstruction Lateral Augmentation for Primary Anterior Cruciate Ligament Reconstruction with Minimum 2- Year Follow-Up: A Systematic Review and Meta-Analysis

Abstract Background Lateral augmentation (LA) of anterior cruciate ligament reconstruction (ACLR) aims to improve the anterolateral stability knee and patient functional outcomes while reducing complication rates. Despite growing evidence popularity, there have been no studies directly comparing main two methods LA; extra-articular tenodesis (LEAT) Anterolateral (ALLR). Aim To establish level I by assessing with minimum two-years follow-up investigating LEAT ALLR patient-reported outcome measures (PROM) post-operative complications. Method This is a systematic review meta-analysis conducted in accordance PRISMA guidelines. The primary investigators (AA/FS) on August 1st, 2022 undertook comprehensive electronic databases. Studies that met our inclusion criteria were selected. Results 14 included study total 2374 patients. 1273 patients (666 male, 607 female) 1101 (818 283 female). Statistically significant improved PROM found group for postoperative International Knee Documentation Committee Scores (MD 2.31; 95% CI: 0.54 – 4.09, P = 0.01), Tegner Activity score 0.79, 0.58 0.99, P<0.01), both 1.43, 0.33 2.52, 0.01) 4.07, 2.67 5.47, P<0.01) groups Lysholm scores. are associated reduced graft re-rupture risk stability. Conclusions LA PROM, stability, when compared iACLR. No differences between ALLR.
