Abstract

Claims (19)

1 . A method of surgically preparing a distal end of a femur of a patient, the method comprising:

reaming an intramedullary canal of the femur with a canal reamer,

attaching a proximal end of a stem trial component to a distal end of a cone reamer,

reaming the distal end of the femur using the cone reamer secured to the stem trial component so as to form a surgically-prepared reamed cavity in the distal end of the femur,

attaching the proximal end of the stem trial component to a distal end of a surgical broach,

advancing a distal end of the stem trial component within the reamed intramedullary canal of the femur,

advancing the surgical broach secured to the stem trial component into the reamed cavity formed in the distal end of the femur during advancement of the distal end of the stem trial component within the reamed intramedullary canal of the femur so as to form a surgically-prepared broached cavity in the distal end of the femur, and

installing a femoral cone augment in the broached cavity formed in the distal end of the femur.

2 . The method of claim 1 , wherein advancing the surgical broach secured to the stem trial component into the reamed cavity formed in the distal end of the femur comprises guiding advancement of the surgical broach with the stem trial component.

3 . The method of claim 1 , further comprising removing the canal reamer from the intramedullary canal prior to advancement of the distal end of the stem trial component within the reamed intramedullary canal.

4 . The method of claim 1 , further comprising removing a previously-installed femoral implant from the femur of the patient prior to reaming the intramedullary canal of the femur with the canal reamer.

5 . A method of surgically preparing a knee of a patient, the method comprising:

reaming an intramedullary canal of a femur of the patient with a femoral canal reamer,

reaming a distal end of the femur using a cone reamer secured to a stem trial component positioned in the reamed intramedullary canal of the femur so as to form a surgically-prepared reamed cavity in the distal end of the femur,

advancing a surgical broach into the reamed cavity formed in the distal end of the femur so as to form a surgically-prepared broached cavity in the distal end of the femur, the surgical broach being secured to the stem trial component positioned in the reamed intramedullary canal of the femur during advancement thereof into the reamed cavity formed in the distal end of the femur, and

installing a femoral cone augment in the broached cavity formed in the distal end of the femur.

6 . The method of claim 5 , wherein advancing the surgical broach into the reamed cavity formed in the distal end of the femur comprises guiding advancement of the surgical broach with the stem trial component.

7 . The method of claim 5 , further comprising removing the canal reamer from the intramedullary canal prior to broaching the distal end of the femur.

8 . The method of claim 5 , further comprising removing a previously-installed femoral implant from the femur of the patient prior to reaming the intramedullary canal of the femur with the femoral canal reamer.
