Abstract

The mechanical actions of individual muscles crossing the knee joint were studied in the frontal plane. Through electrical stimulation, individual knee muscles were selectively activated and the resulting three-dimensional torques at the joint were measured. The isometric experiment was repeated at neutral, 5° varus, 5° valgus positions in the frontal plane and full knee extension to examine the effect of varus/valgus alignment on the muscle actions. In all muscles studied, the varus and valgus malalignment caused the muscles to exert a considerably larger torque in the direction opposite to that of the malalignment.
