Abstract:
1. A method for implanting an orthopedic prosthesis during a knee athroplasty surgery comprising: creating a plurality of apertures during the knee arthroplasty surgery, the apertures extending into a bone from a position that intersects a peripheral rim border that externally delineates a resected surface to be created in the bone that defines a surface shaped to interface with a corresponding fixation surface of the orthopedic prosthesis, wherein the fixation surface is in a generally back to back relation to an articulation surface of the orthopedic prosthesis positioned for contacting a second orthopedic prosthesis; for each of the apertures, inserting a pin from a position outside the border of the resected surface into that aperture, such that the pin extends along an axis parallel to the resected surface with a distal end of the pin positioned within the border of the resected surface; utilizing a cutting instrument to create the resected surface wherein the cutting instrument includes at least one surface that engages at least a portion of at least a line of contact on at least two of the pins that define a plane that is parallel with the resected surface; and operably attaching the corresponding fixation surface of the orthopedic prosthesis to the resected surface.
