Abstract:
1. A method of performing an orthopaedic surgical procedure on a femur of a patient, comprising: assembling a customized patient-specific femoral pin guide assembly by (i) locking a first removable drill bushing into a first hole of a customized patient-specific femoral pin guide, (ii) locking a second removable drill bushing into a second hole of the customized patient-specific femoral pin guide, (iii) locking a third removable drill bushing into a third hole of the customized patient-specific femoral pin guide, and (iv) locking a fourth removable drill bushing into a fourth hole of the customized patient-specific femoral pin guide, positioning the assembled customized patient-specific femoral pin guide assembly in contact with the femur of the patient, inserting a pair of guide pins into the anterior surface of the femur of the patient by (i) advancing a first guide pin of the pair of guide pins through the first removable drill bushing, and (ii) advancing a second guide pin of the pair of guide pins through the second removable drill bushing, drilling a pair of holes into the distal surface of the femur of the patient by (i) advancing a drill bit through the third removable drill bushing and into the distal surface of the femur of the patient, and (ii) advancing the drill bit through the fourth removable drill bushing and into the distal surface of the femur of the patient, removing the customized patient-specific femoral pin guide assembly and the pair of guide pins from the femur of the patient, positioning a patient-universal distal cutting block into contact with the femur of the patient subsequent to removal of the pair of guide pins, and making a distal cut in the femur of the patient with the patient-universal distal cutting block.
