Patent ID: 8920427

Claim:
A method for performing a patellofemoral arthroplasty procedure on a patient's femur, the method comprising: identifying the roof of the intercondylar notch of the patient's femur; positioning an anterior femoral cutting block on the distal end of the patient's femur using the roof of the intercondylar notch as a reference point; establishing a pilot hole in the distal end of the patient's femur using the anterior femoral cutting block; establishing a reference hole in the distal end of the patient's femur using the pilot hole; coupling the anterior femoral cutting block to the patient's femur by positioning a boss of the anterior femoral cutting block in the reference hole; securing the anterior femoral cutting block to the patient's femur by inserting a bone pin into a pin guide hole defined through the boss; performing a plurality of femoral resectioning cuts using the anterior femoral cutting block on the distal end of the patient's femur including establishing a trochlear cavity in the patient's femur that is sized to receive a base of a burring guide having a substantially rectangular shape; coupling the burring guide to the patient's femur by positioning a boss of the burring guide in the reference hole and positioning the base of the burring guide in the trochlear cavity; inserting a burring bit through one of a plurality of openings defined by a frame of the burring guide; and referencing cartilage of the patient's femur using a distal tab of the burring guide extending downwardly away from the frame of the burring guide.
