Comparison of Bennett shift measured at the hinge axis and an arbitrary hinge axis position.
Bennett shift was measured at an arbitrary hinge axis position and at the hinge axis position in 10 subjects. Sixty percent of the arbitrary hinge axis positions were within 5 mm of the hinge axis position. There was no significant difference in the Bennett shift measurements made at the hinge axis and the arbitrary hinge axis positions when measured in 0.25 mm increments. The average immediate Bennett shift was found to be 1.05 mm on the left side and 1.12 mm on the right side when firm guidance was used.
