Functional Outcome of Chronic Anterior Cruciate Ligament Rupture Reconstruction Using Peroneus Longus Tendon Graft According to AOFAS and IKDC Score: A Case Series

Abstract

Introduction: The anterior cruciate ligament (ACL) is a crucial ligament structure of the knee that plays a significant role in knee joint stability and competitive sports performance. In order to reestablish knee stability, ACL reconstruction (ACLR) in the presence of rupture has been recognized as the most common surgical management procedure. Case: This study reported six cases of chronic ACL rupture reconstruction using peroneus longus tendon graft. All patients underwent an arthroscopic ACL repair procedure in Sanglah Hospital Bali. In terms of functional outcome, all patients were assessed using the scoring of AOFAS for the ankle and IKDC for the knee. Result: The functional outcomes of the IKDC and AOFAS score were good from all six patients who already underwent ACL reconstruction using peroneus longus graft with a minimum follow-up of one year. Discussion: Chronic ACL ruptures were successfully treated using the peroneus longus tendon graft. Intraoperatively, there were no significant problems from the harvested peroneus longus tendon graft and ACL reconstruction with the graft. All patients showed no complications, including the local infection following the operation. Rehabilitation procedure post-ACL reconstruction was performed at the Rehabilitation Unit in Sanglah General Hospital. Conclusion: Peroneus longus tendon graft is considered a suitable choice of graft for ACL reconstruction. It presented satisfactory results, effectiveness, and safety based on the AOFAS and IKDC scores.
