Anterior cruciate ligament is one of the most important stabilizing ligaments of the knee. Since the rate of its rupture is significant especially in athletes and even in ordinary people, its reconstruction and surgery are very important and it is important to check the result of surgery. In this study, the short-term results of the reconstruction of the anterior cruciate ligament, which was reconstructed with hamstring tendon or patellar tendon by autograft method, were eva‎luated. At the beginning of the research, three groups of healthy people, people who had anterior cruciate ligament surgery six months before gait test and people who had anterior cruciate ligament surgery nine months before gait test, were given a motion analysis test in order to eva‎luate and compare the analysis results. In the next step, 3D model of knee was simulated in the software environment and entering gait analysis data into the abaqus, analysis and simulation were performed on the anterior cruciate ligament to check the amount of stress and strain applied to the anterior cruciate ligament in a gait cycle. Finally, after examining and comparing the obtained results, it can be concluded that there was no significant difference in the data between the group of surgery people and healthy people (P<0.05). The results obtained from the operated people after the surgery became close to the results of healthy people. By entering the torque values obtained from the laboratory environment into the 3D model, the maximum amount of stress applied to the anterior cruciate ligament (ACL) in a walking cycle for the people who had the surgery 6 months before the gait test was14 MPa and for people who had the surgery 9 months before the gait test was 15 MPa and for a healthy person, was obtained about 17.5 MPa.
