Abstract
A method for preparing a femur and a tibia to receive implants. The method includes mapping location of a femoral guide to a coordinate system using a femoral position sensor mounted to at least one of the femoral guide or another femoral surgical device during preparation of the femur to receive a femoral implant. The method further includes mapping location of a tibial guide to the coordinate system using a tibial position sensor mounted to at least one of the tibial guide or another tibial surgical device during preparation of the tibia to receive a tibial implant.

A method for preparing a femur and a tibia to receive implants comprising:
- mapping location of a femoral guide to a coordinate system using a femoral position sensor mounted to at least one of the femoral guide or another femoral surgical device during preparation of the femur to receive a femoral implant;
- and
- mapping location of a tibial guide to the coordinate system using a tibial position sensor mounted to at least one of the tibial guide or another tibial surgical device during preparation of the tibia to receive a tibial implant.
A method for preparing a femur and a tibia to receive implants comprising:
- mapping location of a femoral guide to a leg mechanical axis using a femoral position sensor mounted to at least one of the femoral guide or another femoral surgical device during preparation of the femur to receive a femoral implant at a position relative to the mechanical axis;
- determining a tibial mechanical axis;
- and
- mounting a tibial guide to the tibia relative to the leg mechanical axis and the tibial mechanical axis using a tibial position sensor mounted to at least one of the tibial resection guide or another tibial surgical device during preparation of the tibia to receive a tibial implant.
A kit for preparing a femur and a tibia to receive implants comprising:
- a femoral position sensor configured to map location of a femoral guide to a coordinate system, the femoral position sensor mounted to at least one of the femoral guide or another femoral surgical device for preparing the femur to receive a femoral implant;
- and
- a tibial position sensor configured to map location of a tibial guide to the coordinate system, the tibial position sensor mounted to at least one of the tibial guide or another tibial surgical device for preparing the tibia to receive a tibial implant.
