Abstract

A method for preparing bone to receive a prosthetic implant, according to an exemplary aspect of the present disclosure includes, among other things, positioning a bone preparation guide assembly on a bone, reaming the bone through a first cut opening of the bone preparation guide assembly, dividing the first cut opening into at least two distinct slots and making cuts in the bone through the at least two distinct slots.

Claims (24)

1. A surgical instrumentation set, comprising:

a bone preparation guide assembly that includes a first cut guide having a first cut opening;

a stabilizer pin received within said first cut opening to separate said first cut opening into at least two distinct slots, said stabilizer pin establishing a size of each of said at least two distinct slots for making cuts in a bone.

2. The surgical instrumentation set as recited in claim 1 , comprising a cutting tool configured to be inserted through said at least two distinct slots.

3. The surgical instrumentation set as recited in claim 2 , wherein said cutting tool is a disposable cutting tool.

4. The surgical instrumentation set as recited in claim 1 , wherein said bone preparation guide assembly includes a second cut guide connected to said first cut guide via a bridge, and said second cut guide includes a second cut opening configured to receive said stabilizer pin to separate said second cut opening into at least two additional distinct slots.

5. The surgical instrumentation set as recited in claim 1 , comprising a slot that extends through said first cut guide adjacent to said first cut opening.

6. The surgical instrumentation set as recited in claim 5 , comprising a distal proximal stylus having a post configured to extend through an opening of said slot.

7. The surgical instrumentation set as recited in claim 1 , wherein said bone preparation guide assembly includes a second cut guide that extends generally perpendicular to said first cut guide.

8. The surgical instrumentation set as recited in claim 1 , wherein said stabilizer pin includes a plug portion received within said first cut opening and a post portion that protrudes out of said first cut opening.

9. The surgical instrumentation set as recited in claim 1 , comprising a second cut guide that extends transversely from said first cut guide, said second cut guide including a second cut opening, and said first cut opening and said second cut opening are configured to create cuts in a femur bone.

10. The surgical instrumentation set as recited in claim 9 , wherein said first cut guide is a trochlear cut guide and said second cut guide is a distal cut guide.

11. The surgical instrumentation set as recited in claim 10 , wherein said trochlear cut guide includes a slot for making additional cuts in said femur bone.

12. The surgical instrumentation set as recited in claim 10 , wherein said distal cut guide includes a depth pin configured to establish a depth of said bone preparation guide assembly relative to an intercondylar notch of said femur bone.

13. The surgical instrumentation set as recited in claim 1 , comprising a plurality of different osteotomes insertable through said bone preparation guide assembly to form said cuts in said bone.

14. The surgical instrumentation set as recited in claim 13 , wherein at least one of said plurality of different osteotomes includes a depth control stop configured to control the depth of said cuts in said bone.

15. The surgical instrumentation set as recited in claim 1 , comprising a slot extending through said first cut guide offset from said first cut opening, said slot including an opening configured to accommodate a distal proximal stylus.

16. The surgical instrumentation set as recited in claim 15 , wherein said distal proximal stylus includes a handle and a post that extends from said handle.

17. The surgical instrumentation set as recited in claim 16 , wherein said post is received through said opening of said slot to align said distal proximal stylus within an intercondylar notch of said bone.

18. A surgical instrumentation set, comprising:

a bone preparation guide assembly including:

a first cut guide including a first cut opening configured to receive a first cutting tool to form a first cut in a bone;

a second cut guide connected to said first cut guide and including a second cut opening configured to receive said first cutting tool to form a second cut in said bone; and

a stabilizer pin insertable within at least said first cut opening to divide said first cut opening into at least two distinct slots, said at least two distinct slots configured to receive a second cutting tool to form angled cuts in said bone.
