Abstract :The aim of this study is to investigate the effect of anterior cruciate ligament insert ignore into journalissuearticles values(ACL); reconstruction on tibial torsion angle insert ignore into journalissuearticles values(TTA); in the operated limb using computed tomography insert ignore into journalissuearticles values(CT); and physical examination methods and to show the relationship between post-operative muscle strength features and TTA by using isokinetic dynamometer. 21 patients between 18 and 36 years old insert ignore into journalissuearticles values(25.4±6.8); who underwent ACL reconstruction with hamstring tendon insert ignore into journalissuearticles values(HT); autograft and then completed the ACL rehabilitation were included in this study. Isokinetic strength measurements were evaluated by Biodex-Multi Joint System-Pro 4 dynamometer. To evaluate TTA; CT, transmalleolar and thigh-foot angle insert ignore into journalissuearticles values(TFA); measurements were carried out. There was no significant TTA differences between 21 operated and non-operated knees for any method insert ignore into journalissuearticles values(p> 0.05);. At the isokinetic evaluation to the extension direction there were a significant differences 60-180º/sec in peak torque value insert ignore into journalissuearticles values(p=0,0001, p=0,003); and average power value insert ignore into journalissuearticles values(p=0,004, p=0,002);. As the percentage of losses in peak torque value to the flexion direction at velocity of 180 º/sec increases, the CT diagnosed angle difference between both knees increases. insert ignore into journalissuearticles values(p<0,01, r=0,548); As the percentage of losses in average power value to the extension direction at the velocity of 60 º/sec increases, the TFA difference between both knees increases. insert ignore into journalissuearticles values(p<0,01, r=0,563); . The isokinetic evaluation findings show that the strength loss between the knees increases the TTA differences. This finding shows the relationship of post-op rehabilitation with TTA varies and re-injury risk. In the isokinetic evaluation, subjects with high loss of strength in the direction of flexion at 180º/sec velocity had higher TTA differences, so rehabilitation protocols should be also focused on muscle endurance.
