Devices and methods for establishing femoral and tibial resection positions in a total knee replacement procedure

A device for establishing a distal femoral resection position in a total knee arthroplasty procedure comprising:

• a tibial support comprising a tibial support cutout and a tibial support insert comprising a pin bore, wherein the tibial support insert is disposed in the tibial support cutout;
• a femoral resection guide alignment arm at least one of coupled to or integral with the tibial support and extending from the tibial support;
• a femoral resection guide comprising a guide body having an anterior face, wherein the alignment arm is disposed along the anterior face of the guide body, wherein the femoral resection guide is configured to be removably attached to a distal femur adjacent to a posterior face of the guide body opposite the anterior face;
• and
• an alignment arm coupling component coupled to the femoral resection guide, wherein the alignment arm coupling component provides a mechanical force on the alignment arm such that the alignment arm is detachably coupled to the femoral section guide,
• wherein the alignment arm is adjustably coupled to the femoral resection guide, providing a range of relative coupling positions of the femoral resection guide relative to the tibial support.
