Intercondylar notch width and inner angle of lateral femoral condyle as the risk factors for anterior cruciate ligament injury in female handball players in Herzegovina.

The principal purpose of this prospective study was to examine intercondylar notch size and the value of inner angle of lateral femoral condyle as the risk factors for noncontact anterior cruciate ligament ACL injury and than to correlate them to the physical values of the athletes such as body mass index (BMI), hight, wight, etc. There are indentified two type of risk factors, external include shoes-surface interaction, type of playing surface, weather conditions and internal include anatomic, neuromuscular, biomechanical and hormonal factors that may predispose female athlets to noncontact injury of ACL. Among anatomic factors, intercondylar notch stenosis and larger inner angle of lateral condyle of femur as the factors which can cause impigement of ACL, were related to an increased risk of injury of ACL. In this study were included 51 female athlete. In the study group there were 24 female handball players with ACL tear and in control group there were 27 female handball players without any type of injury of the knee, who are practicing handball on a daily basis for at least for two years. In the first step, were gathered clinical data performed by orthopaedic surgeon. In the second step, the femoral notch width and the inner angle of lateral condyle of femur were measured on coronal MR-images. Study has shown that value of inner angle of lateral condyle of femur was significantly higher in athletes with ACL tear compared to those without. Value of width of intercondylar notch was statisticaly smaller in athletes with ACL tear, compared to those without. In the conclusion the inner angle of lateral femoral condyle is better predicting factor for ACL tear in young female handball players compared to intercondylar notch width.
