Comparative Study of Arthroscopic ACL Reconstruction with Peroneus Longus Autograft vs Hamstring Autograft

Abstract

Introduction The ACL is 1 of 4 main ligaments in the knee. Ligaments are rope-like structures that connect and hold the bones together to keep the knee stable. There are two components of the ACL, the anteromedial bundle (AMB) and the posterolateral bundle (PLB). The ACL has a microstructure of collagen bundles of multiple types (mostly type I) and a matrix made of a network of proteins, glycoproteins, elastic systems, and glycosaminoglycans. The ACL is innervated by posterior articular branches of the tibial nerve and is vascularized by branches of the middle genicular artery. Anterior cruciate ligament (ACL) reconstruction improves knee stability and function. Phatama et al. reported that there was no significant difference between the peroneus longus and hamstring tendon in terms of tensile strength. Peroneus longus tendon autografts are commonly used in some orthopedic procedures, including spring ligament reconstruction, deltoid ligament reconstruction and medial patellofemoral ligament reconstruction. This is possible, due to the synergistic function of the peroneus longus and peroneus brevis. Some studies have even found that the peroneus brevis is a more effective evertor of the ankle, justifying the harvest of the peroneus longus tendon.
