Method for Performing Bone Cutting

A method for guiding a cutting device to a bone to form chamfer cuts, posterior cuts, and a box cut in the bone, the method comprising:

• positioning a cutting guide on the bone such that an anterior portion of the cutting guide abuts an anterior bone surface and a distal portion of the cutting guide abuts a distal bone surface, the distal portion defining a first guiding side and a second guiding side defining a box-cut shaped opening;
• cutting chamfer cuts in the bone by directing the bone cutting device along each of a plurality of first cutting surfaces disposed at each of the first guiding side and the second guiding side, the first cutting surfaces disposed at an acute angle relative to a distal surface of the guide;
• cutting posterior cuts in the bone by directing the bone cutting device along second cutting surfaces disposed at each of said first guiding side and said second guiding side;
• and
• cutting a box-cut in the bone using a cutting device that cooperates with the first guiding side and the second guiding side at the box-cut shaped opening.
