Differences in tibial rotation and translation in ACL deficient and healthy knees

Abstract

Anterior cruciate ligament (ACL) reconstructive surgery is used for achieving stability of the knee and normal gait pattern. Anterior – posterior translation and internal – external rotation are defined as the leading pathological parameters of the ACL deficiency. Nineteen adult men were exemined in this study. Patients were walking along defined pathway at their own speed. Pathological parameters were defined based on kinematic data obtained by recording with six infrared cameras. Maximal values of the AP translation and IE rotation in early stance phase were recorded during preoperational measurement. Significiant value decrease of the AP translation and IE rotation were recorded after reconstructive ACL surgery.
