Methods for mounting a tibial condylar implant

1. A method for mounting a tibial condylar implant, the method comprising:

forming a tunnel having a proximal end on a lateral, medial, or anterior side of a proximal end of the tibia and a distal end on an at least partially resected lateral or medial facet at the proximal end of the tibia;

positioning a condylar implant over the distal end of the tunnel and over the at least partially resected lateral or medial facet at the proximal end of the tibia;

advancing a fastener into the tunnel from the proximal end of the tunnel;

securing the fastener at least partially disposed within the tunnel to the condylar implant; and

advancing a tubular bone anchor into the tunnel from the proximal end of the tunnel so that the bone anchor engages with the tibia and encircles at least a portion of the fastener secured to the condylar implant.

2. A method as recited in claim 1 , wherein the act of forming the tunnel comprises:

positioning a template over the lateral or medial facet of the tibia;

biasing a tubular guide sleeve against the lateral, medial, or anterior side of the proximal end of the tibia; and

passing a drill tool through the guide sleeve and into the tibia so as to form the tunnel.

3. A method as recited in claim 1 , wherein the condylar implant comprises a bearing plate and a stem projecting from a bottom surface of the bearing plate, the act of positioning the condylar implant comprising inserting a least a portion of the stem within the distal end of the tunnel.

4. A method as recited in claim 1 , wherein the act of advancing the fastener into the tunnel comprises:

removably securing a driver to the fastener; and

using the driver to advance the fastener into the tunnel.

5. A method as recited in claim 1 , wherein the fastener has a drive rod integrally attached thereto, the method further comprising severing the drive rod from the fastener after the fastener is secured to the condylar implant.

6. A method as recited in claim 1 , wherein the act of advancing the tubular bone anchor comprises advancing the tubular bone anchor over a driver extending from the fastener.

7. A method as recited in claim 1 , securing a nut to the fastener so that the nut biases against the bone anchor and thereby tensions the fastener.

8. A method as recited in claim 7 , wherein the act of securing the nut to the fastener comprises screwing the nut onto a portion of the fastener disposed within the bone anchor.

9. A method as recited in claim 7 , further comprising backing the bone anchor a distance back toward the proximal end of the tunnel so as to further tension the fastener.

10. A method for mounting a tibial condylar implant, the method comprising:

forming a tunnel having a proximal end on a lateral, medial, or anterior side of a proximal end of the tibia and a distal end on an at least partially resected lateral or medial facet at the proximal end of the tibia;

positioning a condylar implant over the distal end of the tunnel and over the at least partially resected lateral or medial facet at the proximal end of the tibia;

advancing a fastener into the tunnel from the proximal end of the tunnel;

securing the fastener at least partially disposed within the tunnel to the condylar implant; and

advancing a tubular bone anchor into the tunnel from the proximal end of the tunnel so that the bone anchor engages with the tibia, the fastener being advanced into the tunnel after placement of the bone anchor such that at least a portion of the fastener passes through the bone anchor.

11. A method as recited in claim 10 , wherein the act of securing the fastener to the condylar implant comprises screwing the fastener into the condylar implant so that the fastener biases against bone anchor.

12. A method as recited in claim 10 , further comprising rotating the bone anchor so as to advance the bone anchor toward the proximal end of the tunnel after the fastener is secured to the condylar implant.
