Evaluation of functional outcome following transportal arthroscopic anterior cruciate ligament reconstruction using quadrupled hamstring graft

Abstract

Introduction: The anterior cruciate ligament (ACL) has an important role in preserving the function and stability of the knee joint, and it prevents anterior translation of the tibia. The ACL is the most commonly injured structure of the knee following posttraumatic and sports-related injuries. The treatment of modality for ACL insufficiency was arthroscopic ACL reconstruction. In this study, we followed the transportal approach for ACL reconstruction using a Quadrupled Hamstring graft, and we reported the functional outcome of ACL reconstruction at a minimum follow-up of 6 months. Materials and Methods: This was a prospective outcome study conducted on 32 patients who met the inclusion and exclusion criteria. All patients in this study underwent arthroscopic reconstruction of ACL using quadrupled hamstring tendon graft through transportal technique. The graft was fixed with an endobutton on the femoral side and an interference screw on the tibial side. Patients were assessed for the functional outcome for a minimum of 6 months using the Tegner-Lysholm knee scoring system. Results: The mean age of the patient was 27 years. The majority of involved patients were males. The left side (77.14%) was involved more than the right side (22.86%). The most common cause of ACL injury in this study was road traffic accidents. Preoperative Tegner-Lysholm scores were 20 (62.5%) patients had poor and 12 (37.5%) patients had fair scores. Post-operatively, at 6 months follow-up, 27 patients had excellent, four patients had good scores, and one patient had a fair score. There was a significant improvement in the Tenger-Lysholm scoring system after 6 months of follow-up when compared to preoperatively. Three patients had knee pain and thigh muscle wasting (2 – 3 cm) during follow-up. Conclusions: Transportal arthroscopic ACL reconstruction using Quadrupled Hamstring graft gives excellent functional outcome and knee kinematics.
