Peroneus Longus: Most Promising Autograft for Arthroscopic ACL Reconstruction

Abstract

The ACL injury is one of the most common serious injury in the knee due to its primary stabilizing role and importance in knee biomechanics. ACL injuries are commonly associated with sports injuries and road traffic accidents. The primary aim of ACL reconstruction is to restore the function of the ACL and native kinematics of the knee.1 ACL reconstruction restores the stability of the knee joint and protects the menisci and joint surfaces from further damage.2 The most preferred graft tissues for ACL reconstruction are hamstrings in view of better cosmesis, satisfactory results and to minimize postoperative mobility. However use of peroneus tendon graft is increasing in view of simplicity of the technique. Peroneus longus graft harvest is possible due to synergistic action of peroneus longus and peroneus brevis. Even some studies suggest that peroneus brevis is more effective evertor than peroneus longus, justifying harvest of peroneus longus tendon.3 We evaluated results of arthroscopic ACL reconstruction with peroneus longus graft in 10 patients using Lysholm score and donor site morbidity of foot and ankle after tendon harvesting using AOFAS (American orthopaedic foot and ankle score) and FADI (Foot and Ankle Disability Index) score.5 Peroneus longus tendon is the most promising autograft for ACL reconstruction with advantage of simplicity of harvesting technique, larger graft diameter and minimal graft complications.
