Arthroscopic Anatomic Single Bundle ACL Reconstruction Using Quadrupled Hamstring Autograft

Purpose: To observe the findings and results of arthroscopic anatomic single bundle anterior cruciate ligament (ACL) reconstruction using hamstring tendon autograft. Patients and Methods: This prospective study included 25 patients: 22 male patients and 03 female patients, with an age of 1845 years. The patients underwent arthroscopic anatomic single bundle ACL reconstruction using hamstring tendon autograft. In addition to standard anteromedial (AM) and anterolateral (AL) portals, accessory anteromedial (AAM) portal was used for femoral tunnel placement. In all patients, femoral fixation of graft was done using Endobutton CL. In 8 patients tibial fixation of graft was done using suture disc while in 17 patients tibial fixation of graft was done using interference screw. Results: Medial meniscal tear was found associated in 7 patients and partial medial menisectomy was performed. In 2 patients, tear of both medial and lateral menisci was found, with bucket handle tear of medial meniscus, partial menisectomy was done. At final follow up, 80 % of patients had a negative Lachman test, 16 % of the patients had grade 1+ Lachman test, and 1 patient had grade 2+ Lachman test. None of the patients had grade 3+ Lachman test at final follow up. All the patients with grade 1+ Lachman test were asymptomatic. Pivot shift test was negative in all patients at one year postoperatively. The Lysholm functional score improved from a mean pre-operative value of 63.6 (range 50-81) to a mean of 92.04 (range 76 98) at one year postoperatively. Conclusion: Anatomical single bundle ACL reconstruction using medial portal technique results in excellent functional knee scores.
