Patent ID: 8556830

Claim:
A hand-held display module comprising: a housing sized to be hand-holdable by an orthopaedic surgeon; a display coupled to the housing; and a circuit positioned in the housing, the circuit including a receiver circuit configured to receive joint force data indicative of the joint force between a patient's tibia and femur, wherein the circuit is configured to: determine a joint force value indicative of the medial-lateral balance of the joint force based on the joint force data; display a visual non-numerical icon in a location on the display, wherein the location of the icon on the display is indicative of a center of medial-lateral balance of the determined joint force; change the location of the icon on the display in response to a change in the medial-lateral balance of the joint force; determine a joint force value indicative of the medial-lateral balance and the anterior-posterior balance of the joint force; display a visual indication on the display of the medial-lateral and the anterior-posterior balance of the joint force based on the joint force value; and display a bar on the display, the bar having a first end corresponding to a medial side and a second end corresponding to a lateral side, the circuit being configured to position the first and second ends of the bar based on the anterior-posterior balance of the joint force.
