Systems And Methods For Joint Balancing

A method of determining femoral and tibial implant angulations for a knee arthroplasty procedure, the method comprising the steps of:

• selecting targeted postoperative knee data, the targeted postoperative knee data including targeted implant angulations and implant angulation ranges, the implant angulations including a femoral implant angulation with reference to a femur, and a tibial implant angulation with reference to a tibia;
• determining a plurality of planned implant angulations that are within the targeted postoperative implant angulation ranges based on preoperative knee data and intraoperative knee data, and
• selecting final implant angulations from the plurality of planned implant angulations, wherein the final implant angulations are within the targeted postoperative implant angulation ranges.

A method of determining joint gaps for a knee arthroplasty procedure, the method comprising the steps of:

• selecting targeted postoperative knee data, the targeted postoperative knee data including targeted postoperative joint gaps and joint gap ranges for a femur and a tibia, each joint gap being defined as a distance between the femur and the tibia;
• determining a plurality of planned joint gaps that are within the targeted postoperative joint gap ranges based on preoperative knee data and intraoperative knee data, and
• selecting final joint gaps for the femur and the tibia from the plurality of joint planned gaps, wherein the final joint gaps are within the targeted joint gap ranges.
