GAIT ANALYSIS IN PATIENTS WITH CHRONIC ANTERIOR CRUCIATE LIGAMENT INJURY

Anterior cruciate ligament (ACL) injuries are relatively common in young athletes and quite often require surgical reconstruction. Th e purpose of the ACL reconstruction is to achieve stability in the entire range of motion of the knee and to re-establish a normal gait pattern. For this study, we examined nineteen adult men. Subjects walked along a pathway at their own speed. Motion curves were obtained based on the kinematic data collected using the OptiTrack system with six infrared cameras. Anterior-posterior tibia translation, as the leading ACL pathological parameter, was indirectly determined by monitoring the dif-ference in the length of the distance between markers posi-tioned at the femoral lateral epicondyle and at the tuberosity of the tibia in space and in the sagittal plane.
