    The comparison of tibial torsion angles between elite athletes and sedentary people
    (2018) Bayrak, Ahmet; Kürklü, Galip Bilen; Yargıç, Melda Pelin; Tuncer, Işık
    Torsion is described as a rotational deformation where a long bone turns longitudinally around its own axe. Torsion in tibia is the main reason of children’s stepping in-toe and out-toe. It not only creates orthopedic problems in the future, but also is a risk factor for lower extremity injuries. This study intends to compare Tibial Torsion Angle (TTA) of sedentary people to the soccer players of a Turkish Super Leage team. By comparing TTA angles of elite soccer players who train and compete regularly and have high level of muscle power and endurance to the sedentary control group, it is aimed to determine whether high level soccer training effect TTA. The research was conducted between June-October 2015 on 25 elite soccer players and 25 sedantary people by measuring their right and left tibial torsion angles via transmalleolar measurement with a goniometer. Non-parametric tests were used in statistical analysis, Mann-Whitney U test was used for comparisons. There was not a significant difference in right-left measurements within groups. Between groups right TTA showed no significant difference but left TTA measurements varied significantly (p0.05). These findings suggest that tibial torsion angle differs according to physical activity level. It is understood that regular and long-time exercise programmes can change TTA.

    The Evaluation of Tibial Torsion Angle After Anterior Cruciate Ligament Reconstruction
    (Selçuk Üniversitesi, 2020 Eylül) Kürklü, Galip Bilen; Özdengül, Faik; Çelebi, Mehmet Mesut; Bayrak, Ahmet; Görmüş, Zülfikare Solak; Işık, Bülent; Zergeroğlu, Ali Murat
    The aim of this study is to investigate the effect of anterior cruciate ligament (ACL) reconstruction on tibial torsion angle (TTA) in the operated limb using computed tomography (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 (25.4±6.8) who underwent ACL reconstruction with hamstring tendon (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 (TFA) measurements were carried out. There was no significant TTA differences between 21 operated and non-operated knees for any method (p> 0.05). At the isokinetic evaluation to the extension direction there were a significant differences 60-180º/sec in peak torque value (p=0,0001, p=0,003) and average power value (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. (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. (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.
