Background: Partial tears of the anterior cruciate ligament (ACL) are frequent. Depending on the injury pattern; the patients demonstrate a wide spectrum of clinical symptoms. Recent interest focused on establishing pre and intraoperative ways of assessing the different types of symptomatic one bundle tears in order to perform an individual ACL augmentation. The aim of this study was to evaluate the clinical outcome of the ACL augmentation procedure for patients with partial ACL ruptures. Materials and Methods: Thirty patients with an ACL partial tear were included at this study; anatomic single bundle augmentation using the semi-tendinosus and gracilis auto-grafts was done. 27 cases (90%) were males and 3 cases (10%) were females. Of the knees involved, 16 were right (53.3%) and 14(46.7%) were left. Age ranges from 20 to 30 years and the mean age was 25.2±3.2 years and the average time between the injury and the surgical interference was 8.77± 8 months. Affected bundle among patients was PL in 17 patients (56.7%) and 13 patients (43.3%) with affected AM bundle. Follow up on regular basis after reconstruction was done for one year postoperatively. Assessment was done before surgery and at the end of follow up using IKDC objective score and lysholm score. Results: The overall results of the present study, as measured by the IKDC evaluation system after 12 months follow up, were 23 patients out of 30 patients (76.7%) had score A and 7. patients out of 30 patients (23.3%) had score B. The Lysholm score improved from a mean 57.1 (before surgery) to 87.8 at the end of follow up
