Functional Outcomes After Single-Bundle Anterior Cruciate Ligament Reconstruction: A Comparative Analysis of Hamstring and Peroneus Longus Autografts

Year: 2025

Type: article

Abstract: BACKGROUND: The anterior cruciate ligament (ACL) is frequently injured in activities that involve pivoting the knee. With the development of arthroscopic techniques for reconstructing the ACL, researchers have been exploring improved graft options. This study compares the functional outcomes of two different graft sources: peroneus longus (PL) graft and hamstring graft. METHODOLOGY: This prospective cohort study included 56 single-bundle arthroscopic ACL reconstruction patients, randomized into the PL or hamstring graft groups. Standardized surgical techniques were used, and both groups followed the same rehabilitation protocol after surgery. Knee functional outcomes were measured using International Knee Documentation Committee (IKDC) and Lysholm scores, and clinical evaluations included anterior drawer, Lachman, and pivot shift tests. RESULTS: Results indicated no significant differences (p > 0.05) in functional outcomes measured by IKDC and Lysholm scores between the two graft types. Additionally, graft harvest time was significantly shorter, and graft diameter was significantly larger for PL grafts. CONCLUSION: Both hamstring and PL grafts are effective for ACL reconstruction, enhancing knee stability and function with minimal donor site issues. The PL tendon, with its greater strength, thickness, and minimal donor site morbidity, proves to be a highly effective and safe autograft option.
