Functional outcomes and hop tests results in anterior cruciate ligament reconstruction patients with adjustable loop fixation: 2-years follow-up

Abstract

BACKGROUND: Grafts are ultimately integrated into the bone tunnels by either screws, cross-pins, or cortical suspension devices in anterior cruciate ligament (ACL) reconstruction. Investigation the usage of adjustable loop button is inadequate. AIM: The aim of this study was to identify knee functional outcome and serial hop test in ACL reconstruction with adjustable loop button in 2-years follow-up. METHODS: Chronic isolated ACL ruptured patients were reconstructed with adjustable loop button using peroneus longus autograft. We recorded knee functional outcome score using Tegner-Lysholm score, Modified Cincinnati score, and International Knee Documentation Committee (IKDC) at pre-operative and 2-years follow-up. Serial hop test was assessed at 6 months after surgery. RESULTS: Forty-seven patients fulfilled inclusion criteria with median age 22.0. Evaluation of functional outcome of Tegner-Lysholm score, Modified Cincinnati score, and IKDC showed significant improvement at 2-years follow-up compared to pre-operative. Serial hop test showed excellent result at 6 months after surgery. CONCLUSION: The result of knee functional score (Tegner-Lysholm score, Modified Cincinnati score, and IKDC) and serial hop test in ACL reconstruction with adjustable loop using peroneus longus autograft was excellent at 2-years follow-up. LEVEL OF EVIDENCE: Level 2, Retrospective Cohort Study.
