Abstract Background: In recent years there is an increasing interest in double bundle (DB) anterior cruciate ligament (ACL) reconstruction in order to improve the anatomical, biomechanical and clinical outcome of the procedure. Objectives; Evaluation of the outcome of arthroscopic double bundle ACL reconstruction using four tunnels technique with autograft hamstring tendons for athletic patients. Patients and methods: Fifteen athletic male patients suffering from ACL injury with the mean age at time of operation was 24.3 years (average 18-34 years) were operated up on using four tunnels technique and fixation was done by two femoral end buttons and two tibial interference screws. Results: After a follow up period with a mean 26 months (range 12-42 months), according to the International Knee Documentation committee (IKDC) score, 14 patients (93.3%) became normal and near normal, and one patient (6.7%) abnormal. The Lysholm score changed from 56 points preoperative (range 30-72) to 93 points (range 45-100) at the end of follow up. Thirteen patients (86.6%) had normal Lachman and anterior drawer tests. Twelve patients had negative pivot shift test. Nine patients (60%) had near normal thigh girth in comparison to the healthy side. All 15 patients reached 100% range of motion in comparison to the other healthy side at the end of follow up. Conclusion: ACL reconstruction with the double bundle technique is good for stability of the knee. Long term studies should be performed and the number of patients should be increased.
