1. 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.

Abstract
A hand-held display module includes a housing, a display coupled to the housing, and a circuit positioned in the housing and coupled to the display. The circuit includes a receiver circuit configured to communicate with a sensor module positioned in a knee joint of a patient to receive joint force data indicative of the joint force of the patient'"'"'s knee joint. In one mode, the circuit is configured to display a visual indication of the medial-lateral balance of the joint force based on the joint force data. In a second mode, the circuit is configured to display a visual indication of the medial-lateral and the anterior-posterior balance of the joint force.

12. A hand-held display module comprising:
-
a display; a receiver circuit configured to receive joint force data indicative of the joint force between a patient'"'"'s tibia and femur, a processor coupled to the receiver circuit and the display; and a memory device coupled to the processor and having stored therein a plurality of instructions, which when executed by the processor, cause the processor to; determine a joint force value indicative of the medial-lateral balance of the joint force based on the joint force data; display a non-numerical icon in a location on the display, wherein the location of the icon on the display is indicative of a center of the 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 medial force value indicative of a medial component of the joint force based on the joint force data; determine a lateral force value indicative of a lateral component of the joint force based on the joint force data; display the medial force value and the lateral force value on the display; 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 first and second ends of the bar being displayed in a position based on the anterior-posterior balance of the joint force. - View Dependent Claims (13, 14)

15. A hand-held display module comprising:
-
a housing sized to be hand-holdable by an orthopaedic surgeon; a display coupled to the housing; a screenshot button usable to store a screenshot of an image displayed on the display; 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; and display a vertical line on the display in a position based of the medial-lateral balance of the joint force that is indicated in a corresponding screenshot and an angled line on the display in a position based of the anterior-posterior balance of the joint force that is indicated in the corresponding screenshot. - View Dependent Claims (16, 17, 18, 19, 20)
