Systems and Methods for Prosthetic Component Orientation

A system for determining an orientation parameter value of a prosthetic component, the system comprising:

• an input device configured to receive a first desired separation distance between a tibial prosthetic component and a femoral prosthetic component at a first flexion position of a knee joint;
• a processor, operatively coupled to the input device and configured to:
• estimate a first estimated separation distance between the tibial prosthetic component and the femoral prosthetic component at the first flexion position of the knee joint for at least one potential orientation of the femoral prosthetic component;
• and
• determine a first orientation parameter value of the femoral prosthetic component by comparing the first estimated separation distance to the first desired separation distance;
• and
• a display operatively coupled to the processor and configured to output the first orientation parameter value.

A computer-implemented method for determining an orientation of a prosthetic component, the method comprising:

• recording relative positions of a tibia and a femur at a plurality of flexion positions of the knee;
• receiving a plurality of looseness values via a user interface, each of the plurality of looseness values corresponding to a looseness preference between a tibial prosthetic component and a femoral prosthetic component for one of the plurality of flexion positions of the knee;
• determining an orientation of the femoral prosthetic component based on the recorded relative positions of the tibia and the femur and the received looseness values;
• and
• outputting the orientation of the femoral prosthetic component via a display.
