Abstract:
1. A method of preparing a distal femur to receive a prosthetic femoral component, the prosthetic femoral component including a first articulating surface, an opposing first bone-contacting surface, and a box that projects proximally from the first bone-contacting surface to a top surface, the method comprising the steps of: providing a body having a second articulating surface that is shaped to replicate the first articulating surface and a second bone-contacting surface that is shaped to replicate the first bone-contacting surface, the body including a medial side and a lateral side that define an opening therebetween; positioning the second bone-contacting surface of the body against the distal femur; attaching a box cut guide to the body such that the box cut guide spans the medial and lateral sides of the body across the opening, the box cut guide including a first reference surface located in a first cut plane; guiding a first cutting tool across the first reference surface to prepare a first resected surface of the distal femur, the first resected surface of the distal femur located in the first cut plane; attaching a second cut guide to the body at a different location than the box cut guide such that the second cut guide spans the medial and lateral sides of the body across the opening, the second cut guide including a second reference surface located in a second cut plane, the second cut plane intersecting the first cut plane at an obtuse angle; guiding a second cutting tool across the second reference surface to prepare a second resected surface of the distal femur, the second resected surface of the distal femur located in the second cut plane; removing the body from the distal femur; and positioning the first bone-contacting surface of the prosthetic femoral component against the distal femur with the top surface of the box bordering the resected surface of the distal femur.
