A Study Comparing the Effectiveness of Hamstring Tendon Graft Versus Quadriceps Tendon Graft in Press Fit Anterior Cruciate Ligament Reconstruction

Abstract

Background: Press fit ACL reconstruction is a surgical procedure used to repair a torn anterior cruciate ligament (ACL) in the knee. During press fit ACL reconstruction, a graft is used to replace the torn ACL. The graft can be harvested from various sources, such as the patient's own hamstring tendons or patellar tendon, or from a donor. The graft is then inserted into tunnels created in the femur and tibia bone. The term "press fit" refers to the technique used to secure the graft within these bone tunnels. Instead of using screws or other fixation devices, press fit ACL reconstruction relies on tight fitting of the graft within the tunnels. Objective: This study aimed to compare the subjective, objective, and radiological results of press fit anterior cruciate ligament (ACL) reconstruction using hamstring tendon graft versus quadriceps tendon graft. Methods: A total of 50 patients with complete ACL tears underwent press fit ACL reconstruction between March 2016 and June 2019. Among them, 25 patients received a hamstring tendon graft, and another 25 patients received a quadriceps tendon graft. Results: The study demonstrated favorable outcomes of press fit ACL reconstruction, with improvements observed in all 50 patients when comparing postoperative to preoperative parameters. The results also showed comparable outcomes between the quadriceps and hamstring groups in terms of subjective, objective, and radiological measures. Conclusion: The press fit technique for ACL reconstruction is a successful method of graft fixation that offers advantages such as fewer complications, lower cost, and easier revision compared to other commonly used techniques.
