Knee Laxity Measurement Device. This picture depicts the side view and anterior view of the Knee Laxity Measurement Device in use. Shown are the 6-DOF universal force/moment sensor and handle bar (1) attached to the Aircast boot. The three magnetic trackers (2) are attached to the boot, tibia, and femur to record measurement of rotational knee laxity.
