Abstract
Devices, systems and methods for controlling gap height for posterior resection in a partial knee arthroplasty can comprise A) use robotic surgery planning software to adjust an extension gap to suit a flexion gap to manually position a manual posterior cut guide; B) use a surgical navigation system to determine a femur rotation axis to properly manually position a manual posterior cut guide; C1) use shims to adjust the position of a manual posterior cut guide; C2) use a robotically-guided femur and tibia partial cut guide block to position a robot-configured posterior cut guide relative to the distal end of a femur; and D) use a robotically-guided femur and tibia partial cut guide block to guide pin holes for a robot-configured posterior cut guide relative to the distal end of a femur.
