Patent ID: 8790347

Claim:
A method of arthroscopically-assisted preparation of a bone to accept an implant, the method comprising the steps of: introducing a first arthroscopic cylindrical rasp through an arthroscopic portal and into a joint and removing bone to form a first tunnel or socket having a first depth, a first diameter, and a first longitudinal axis forming a first angle with a surface of the bone; replacing the first arthroscopic cylindrical rasp with a second arthroscopic cylindrical rasp, the second arthroscopic cylindrical rasp being provided with a cutter having an outer cylindrical surface and two opposing surfaces, wherein one of the two opposing surfaces is provided with a first plurality of teeth and wherein only a portion of the outer cylindrical surface is provided with a second plurality of teeth; and introducing the arthroscopic cylindrical rasp through the arthroscopic portal and into the joint and removing bone from the first tunnel or socket with the second cylindrical rasp to enlarge the first tunnel or socket to form a second tunnel or socket having a second depth, a second diameter, and a second longitudinal axis forming a second angle with the surface of the bone, wherein the second depth is greater than the first depth and the second diameter is greater than the first diameter, wherein the first arthroscopic cylindrical rasp cuts in one direction and the second arthroscopic cylindrical rasp cuts in an axial and a rotational directions.
