Surgical instruments and method of surgically preparing a patient's tibia

1. A method of surgically preparing a proximal end of a tibia, the method comprising:

inserting a broach into a medullary canal of the tibia to engage a plurality of cutting teeth of the broach with the tibia,

securing a housing of an attachment device to the broach by inserting a mounting shaft of the attachment device into an opening in the broach to secure the housing of the attachment device to the broach,

sliding a mounting frame along a rail toward the housing,

attaching a cutting block to the mounting frame, the cutting block having a cutting guide defined therein,

resecting the proximal end of the tibia using the cutting guide to form a surgically-prepared surface,

removing the broach from the medullary canal,

positioning a tibial base trial on a tibial sleeve trial,

inserting the tibial sleeve trial into the medullary canal, and

positioning the tibial base trial on the surgically-prepared surface.

2. The method of claim 1 , wherein attaching the cutting block to the mounting frame includes operating a control knob to move a locking tab of the mounting frame into engagement with the cutting block.

3. A method of surgically preparing a proximal end of a tibia, the method comprising:

inserting a broach into a medullary canal of the tibia, the broach including (i) a tapered outer surface and (ii) a plurality of cutting teeth formed on the tapered outer surface,

securing an attachment device to the broach by actuating a lever of the attachment device to engage the lever with a flange of the broach,

attaching a cutting block to the attachment device, the cutting block having a cutting guide defined therein,

resecting the proximal end of the tibia using the cutting guide to form a surgically-prepared surface,

positioning a tibial base trial on the surgically-prepared surface, and

securing the tibial base trial to the broach positioned in the medullary canal.

4. The method of claim 3 , further comprising:

inserting a base insert into an opening defined in the tibial base trial, the base insert including a lug, and

positioning a tibial bearing trial over the lug of the base insert.

5. The method of claim 3 , wherein securing the tibial base trial to the broach includes inserting a post of the tibial base trial into an opening in the broach.

6. The method of claim 3 , further comprising securing a stem trial to the broach before inserting the broach into the medullary canal.

7. The method of claim 3 , wherein securing the attachment device to the broach includes inserting a mounting shaft of the attachment device into an opening in the broach.

8. The method of claim 3 , wherein attaching the cutting block to the attachment device includes operating a control knob to move a locking tab of the attachment device into engagement with the cutting block.

9. The method of claim 3 , further comprising withdrawing a broach insert from a slot defined in the broach and disengaging the cutting teeth of the broach insert from the tibia.

10. The method of claim 3 , further comprising:

positioning a trial component including a bearing surface on the tibial base trial, and

performing a trial reduction with the tibial base trial secured to the broach.

11. The method of claim 1 , further comprising inserting a keel punch through a slot defined in the tibial base trial and into the surgically-prepared surface of the tibia.

12. The method of claim 1 , wherein securing the attachment device to the broach includes actuating a lever of the attachment device to engage the lever with a flange of the broach.

13. The method of claim 1 , wherein sliding a mounting frame along a rail toward the housing includes operating a control knob to move a locking tab of the mounting frame into engagement with the rail.

14. The method of claim 1 , further comprising:

inserting a base insert into an opening defined in the tibial base trial, the base insert including a lug, and

positioning a tibial bearing trial over the lug of the base insert.

15. The method of claim 1 , wherein securing the attachment device to the broach includes actuating a lever of the attachment device to engage the lever with a flange of the broach.

16. A method of surgically preparing a proximal end of a tibia, the method comprising:

inserting a broach into a medullary canal of the tibia to engage a plurality of cutting teeth of the broach with the tibia,

securing a housing of an attachment device to the broach by actuating a lever of the attachment device to engage the lever with a flange of the broach,

sliding a mounting frame along a rail toward the housing,

attaching a cutting block to the mounting frame, the cutting block having a cutting guide defined therein,

resecting the proximal end of the tibia using the cutting guide to form a surgically-prepared surface,

removing the broach from the medullary canal,

positioning a tibial base trial on a tibial sleeve trial,

inserting the tibial sleeve trial into the medullary canal, and

positioning the tibial base trial on the surgically-prepared surface.

17. A method of surgically preparing a proximal end of a tibia, the method comprising:

inserting a broach into a medullary canal of the tibia, the broach including (i) a tapered outer surface and (ii) a plurality of cutting teeth formed on the tapered outer surface,

securing an attachment device to the broach by inserting a mounting shaft of the attachment device into an opening in the broach,

attaching a cutting block to the attachment device, the cutting block having a cutting guide defined therein,

resecting the proximal end of the tibia using the cutting guide to form a surgically-prepared surface,

positioning a tibial base trial on the surgically-prepared surface, and

securing the tibial base trial to the broach positioned in the medullary canal.
