System and method for displaying joint force data

A computer assisted orthopaedic system comprising:

• a display
• a sensor module the sensor module including a sensor array having (i) a plurality of medially located pressure sensors configured to generate medial sensor signals indicative of a medial joint force between a patient's tibia and a medial condyle of the patient's femur and (ii) a plurality of laterally located pressure sensors configured to generate lateral sensor signals indicative of a lateral joint force between the patient's tibia and a lateral condyle of the patient's femur, the sensor module being configured to wirelessly transmit medial force data indicative of the medial joint force and lateral force data indicative of the lateral force;
• a computer coupled to the display and including a receiver circuit configured to receive the medial and lateral force data, the computer being configured to:
• determine position data indicative of a position of a patient's femur and a patient's tibia;
• display an image of the patient's femur and the patient's tibia based on the position data;
• determine a medial force value based on the medial joint data;
• determine a lateral force value based on the lateral joint data;
• and
• display the medial force value and the lateral force value on the display.

A method for operating a computer assisted orthopaedic surgery system, the method comprising:

• determining position data indicative of a position of a patient's femur and a patient's tibia;
• displaying an image of the patient's femur and the patient's tibia based on the position data;
• determining a medial force value indicative of a medial component of the joint force based on the joint force data,
• determining a lateral force value indicative of a lateral component of the joint force based on the joint force data, and
• displaying the medial force value and the lateral force value on the display.
