GAIT ANALYSIS IN PATIENTS WITH CHRONIC ANTERIOR CRUICATE LIGAMENT INJURY
Abstract
Anterior cruicate ligament (ACL) injuries are relatively common in young athletes that quite often require surgical reconstruction. The purpose of the ACL reconstruction is to achieve stability in the entire range of motion of the knee and the establishment of the normal gait pattern.
For this study we examined nineteen adult men. Motion curves were obtained on the basis of the kinematic data collected using OptiTrack system with six infrared cameras. Anterior - posterior tibia translation, as the leading ACL pathological parameter, is indirectly determined by monitoring the difference in length of the distance between markers positioned at the femoral lateral epycondile and at the tuberosity of the tibia, in space and in sagittal plane. Also, the angle of the internal - external rotation was monitored using the gradient of the tangent line of the motion curve.
The results obtained in this research reveal that the more precise diagnosis of the ligament instability can be set, providing relevant indicators for the type of treatment.
