This study evaluates changes in the knee following anterior cruciate ligament
(ACL) injuries by presenting the kinematic characteristics of the ankle and hip
joints and the pelvis, and assessing the dynamic forces applied by knee joint
muscles under isokinetic conditions to identify compensatory mechanisms.
Seventeen ACL-deficient males, 16-47 years of age, participated in the study, and
measurements were taken an average of 24.4 months after their injuries occurred.
Vicon, a three-dimensional motion analysis system, was used to examine the
participants' locomotive characteristics. Isokinetic tests were carried out using
Easytech Genu 3 at two velocities 60 and 180 degrees /s. We found that deviations
from normal gait were most common in the ACL-deficient knee, and that there was
also a noticeable impact on the functioning of other joints in the same limb.
However, even chronic knee joint laxity did not result in a considerable change
in a participant's gait stereotype. Measurements showed a reduction in muscular
strength in knee joint extensors and flexors in isokinetic contraction in the
developed joint moments of the muscle groups under research compared with the
healthy limb.
