Effect of muscle compensation on knee instability during ACL-deficient gait

Article Abstract:

An investigation was undertaken to determine whether an isolated change in either quadriceps or hamstrings muscle force is sufficient to stabilize the ACL-deficient (ACLd) knee during gait. The model simulations showed that increased hamstrings force was sufficient to stabilize the ACLd knee during gait and reduced quadriceps force was insufficient to restore normal anterior tibial translation for portions of the gait cycle.

Muscle, ligament, and joint-contact forces at the knee during walking

Article Abstract:

Muscle-ligament interactions for the normal and anterior cruciate ligament (ACL)-deficient knee when subjects walked at their preferred speeds are described. Anterior tibial transaction in the ACL-deficient keen can be reduced to the level calculated for the intact knee.
