Abstract: Methods and systems for planning a joint replacement surgical procedure are disclosed. A musculoskeletal model for a patients joint and patient biometric data are received. A joint distraction device is positioned in the patients joint during the joint replacement surgical procedure, and the position and orientation of the joint distraction device are tracked as the patient's joint is moved through a range of motion in order to determine a magnitude of a force applied to the joint distraction device. A surgical plan for performing the joint replacement surgical procedure is provided based on the magnitude of the force applied throughout the range of motion, the musculoskeletal model, and the patient biometric data. The surgical plan includes implant position information, bone resection information, and/or ligament balancing information.
