Difference in Functional Outcomes Between Anterior Cruciate Ligament (ACL) Reconstruction Combined with Lateral Extra-Articular Tenodesis (LEAT) and Without LEAT Combination for ACL Injury Patients in the Third and Sixth Months Postoperative

Introduction: Anterior Cruciate Ligament (ACL) rupture is a common knee injury, particularly affecting young, active individuals. Reconstruction techniques for ACL injury, with or without Lateral Extra-Articular Tenodesis (LEAT), play a crucial role in determining patient outcomes. This study aims to compare the functional outcomes of ACL reconstruction with LEAT and without LEAT. Materials and Methods: This retrospective cohort study was conducted from February 2023 to February 2024 at Prof. IGNG Ngoerah Hospital, involving 40 patients who underwent ACL reconstruction (18 with LEAT, 22 without LEAT). Patient outcomes were evaluated at 3, 6, and 12 months postoperatively using IKDC, Tegner, KOOS scores, and Rolimeter measurements. Statistical analysis included chi-square and independent t-tests to assess differences between the two groups. Results: The baseline characteristics showed no significant differences between the groups, indicating no confounding factors. Males comprised 67.5% of the cohort, with the majority (72.5%) aged 18-30 years, and 57.5% were private sector employees. The most common injury mechanism was sports-related (50%). The most prevalent symptom was knee pain (52.5%). Statistically significant improvements were observed in the LEAT group compared to the non-LEAT group in KOOS, IKDC, and Rolimeter scores at both 3 and 6 months (p<0.001). Conclusion: ACL reconstruction with LEAT demonstrated superior clinical and functional outcomes compared to reconstruction without LEAT, suggesting that this technique may provide enhanced stability, especially for athletes and individuals engaging in pivot-heavy activities.
