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. Nonparametric 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 (p˂0.05). 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.

There is no consensus about which graft type should be used in patients who will undergo anterior cruciate ligament (ACL) reconstruction so far. In this study, it was aimed to compare the quality of life, knee functions, and isokinetic muscle strength of patients who underwent ACL reconstruction with hamstring tendon (HT) and bone–tendon–bone (BTB) autografts. Total 40 patients with ACL reconstruction (20 in HT group and 20 in BTB group), at least 1 year after the operation, all injured during sports activity were included in this study. Flexor and extensor muscle groups of both affected and unaffected knees at angular velocities of 60 and 180 degrees/s were recorded. Lysholm knee score questionnaire and Short Form (SF)-36 were administered to all patients before the isokinetic tests. No statistically significant differences were found between the groups at any angular velocity in isokinetic evaluation. Furthermore, there was no statistically significant difference between the groups in regard to Lysholm score. However, there was a statistically significant difference between the groups in SF-36 physical function domain score (p < 0.01). The results demonstrated that the SF-36 questionnaire can easily be applied to this patient population. There was only one significant difference in the SF-36 physical function component scores between the two groups. The quality of life, knee functions, and isokinetic muscle strength were similar in patients who underwent ACL reconstruction with HT and BTB.
