    Abstract:
    The purpose of the present study is to evaluate the rehabilitation of different treatments of ACL ruptured knees by means of gait parameters. The gait analysis results in two surgically treated patient groups (patellar tendon autograft reconstructions (n = 35) and augmented repairs (n = 15) and one non-surgically treated patient group (n = 19) are evaluated by means of gait parameters of normal controls (n = 30). The technical equipment included an optoelectronic system for recording the kinematics of gait (Primas, NL) and two force plates for measuring the ground reaction forces (Kistler, CH). The moments acting on joints can be determined experimentally with both systems. It can be shown from special gait tests that the derived quantitative evaluation parameters are independent from the gait analysis conditions. One year after surgery, both the patellar tendon autograft reconstruction group and the augmented repair group show clear deficiencies in gait parameters compared with the controls. In particular this concerns the midstance extension motion of the knee (p < = 0.01) and the extension moments acting on the knee joint during the stance phase (sagittal plane, p < = 0.01). The deficiencies of both surgically treated groups are approximately the same. However, one year after occurrence of the disruption the non-surgically treated group cannot be distinguished from the controls. From this and from additional pre-surgical measurements, it can be concluded, that operating has an important influence on gait parameters. The role of the gait analysis results has been discussed.
