Abstract

This disclosure relates to arthroscopic resurfacing techniques for treating diseased bone. The techniques include passing a graft into a joint and fixating the graft against an articulating surface of a bone of the joint. A method for resurfacing a bone according to an exemplary aspect of the present disclosure includes, among other things, sizing a graft based on a replicate of a bone, arthroscopically positioning the graft against an articulating surface of the bone, and securing the graft to the bone using at least one suture anchor.

First claim

What is claimed is:

1. A method for resurfacing a bone, comprising:
sizing a graft based on a replicate of a bone;
arthroscopically positioning the graft against an articulating surface of the bone; and
securing the graft to the bone using at least one suture anchor;
wherein the bone is a patella bone and the method includes:
passing a plurality of flexible strands through the graft;
shuttling the plurality of flexible strands one by one into a joint space surrounding the patella bone;
extracting free ends of each of the plurality of flexible strands through skin;
pulling the graft into place against the articulating surface using the plurality of flexible strands; and
anchoring the graft to the patella bone using the at least one suture anchor.

2. The method as recited in claim 1 , wherein the replicate of the bone is a rapidly prototyped model of the bone.

3. The method as recited in claim 1 , comprising:
obtaining a radiographical image of the bone;
communicating the radiographical image to a computer system to generate a 3D model of the bone; and
communicating the 3D model to a rapid prototyping system to create the replicate of the bone.

4. The method as recited in claim 1 , comprising practicing a surgical procedure on the replicate of the bone prior to performing the steps of arthroscopically positioning the graft and securing the graft to the bone.

5. The method as recited in claim 1 , wherein the graft is an acellular dermal extracellular matrix.

6. The method as recited in claim 1 , wherein the at least one suture anchor is a knotless suture anchor.

7. The method as recited in claim 1 , wherein sizing the graft includes cutting the graft into a desired size and shape.

8. The method as recited in claim 1 , comprising debriding the articulating surface prior to the step of arthroscopically positioning the graft.

9. The method as recited in claim 1 , comprising preparing drill tunnels in the bone prior to the step of arthroscopically positioning the graft.

10. The method as recited in claim 1 , comprising folding the graft prior to the step of arthroscopically positioning the graft.

11. A method for resurfacing a bone, comprising:
sizing a graft based on a replicate of a bone;
arthroscopically positioning the graft against an articulating surface of the bone;
creating a bleeding bone bed on the articulating surface prior to the step of arthroscopically positioning the graft; and
securing the graft to the bone using at least one suture anchor.

12. The method as recited in claim 11 , wherein the step of arthroscopically positioning the graft includes:
attaching a plurality of flexible strands to the graft; and
passing the graft into a joint space surrounding the bone using the plurality of flexible strands.

13. The method as recited in claim 12 , wherein the step of passing the graft into the joint space includes shuttling the plurality of flexible strands through tunnels formed in the bone using a shuttling device.

14. The method as recited in claim 11 , wherein using the at least one suture anchor includes:
passing a flexible strand through the graft;
loading the flexible strand through a first portion of the at least one suture anchor;
inserting the first portion of the at least one suture anchor into a hole formed in the bone;
tensioning the flexible strand; and
inserting a second portion of the at least one suture anchor into the hole to trap the flexible strand between the bone and the second portion.

15. A method for resurfacing a bone, comprising:
sizing a graft based on a replicate of a bone;
arthroscopically positioning the graft against an articulating surface of the bone;
securing the graft to the bone using at least one suture anchor; and
applying a bone marrow concentrate between the graft and the articulating surface after the step of securing the graft to the bone.

16. A method for resurfacing a bone, comprising:
sizing a graft based on a replicate of a bone;
arthroscopically positioning the graft against an articulating surface of the bone; and
securing the graft to the bone using at least one suture anchor;
wherein the bone is a talus bone and the method includes:
preparing crossing tunnels through the talus bone;
passing sutures through the crossing tunnels;
pulling the graft into place against the articulating surface of the talus bone using the sutures; and
anchoring the graft to the talus bone using the at least one suture anchor.
