1. A method for accessing an articular surface of a bone comprising:
- forming a passage through a portion of said bone, said passage providing an opening in said articular surface and an opening in said bone;
inserting a flexible tether through said passage;
conveying a prosthetic resurfacing device to a location proximate said articular surface using said tether; and
imparting a rotational force to urge said prosthetic resurfacing device towards said passage.

Abstract
A method according to one embodiment may provide access to an articular surface of a bone. The method includes forming a passage through at least a portion of the bone. The passage provides an opening in the articular surface. The method further includes inserting a tether through the passage. The tether inserted through the passage can be coupled to at least one device from an insertion site remote from the articular surface. The tether can be withdrawn through the passage to convey the device to a location proximate the articular surface.

5. A method for creating an implant site on an articular surface of a bone comprising:
-
drilling a passage through said bone, wherein a longitudinal axis of said passage extends substantially normal to said articular surface; advancing a drive shaft at least partially within said passage; advancing a shuttle within said passage in said bone; conveying a reamer to said articular surface using said shuttle; excising an implant site in a portion of said articular surface about said defect using said reamer; conveying a threaded device to said implant site using said shuttle; and threadably driving said threaded device into said passage.

6. A method for creating an implant site on an articular surface of a bone comprising:
-
locating a locating feature of a drill guide generally normal to said articular surface and at least partially about a defect on said articular surface, said locating feature being aligned with a drill bushing to define a working axis extending therethrough; advancing a drill bit at least partially through a drill bushing of said drill guide along a working axis to drill a passage through said bone substantially normal to said articular surface and provide an opening on said articular surface about said defect, said working axis extending through said drill guide and said locating feature; advancing a drive shaft at least partially within said passage; advancing a shuttle within said passage in said bone, said shuttle further configured to be coupled to a device and to deliver said device to said working axis; conveying a reamer to said articular surface using said shuttle; coupling said drive shaft to said reamer to excise an implant site in a portion of said articular surface about said defect; conveying a threaded device to said implant site using said shuttle; and threadably driving said threaded device into said passage. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
