JOINT REPLACEMENT COMPONENT
First Claim
1. A method of replacing at least a portion of a joint in a patient, comprising:
- positioning an alignment guide on a diseased or damaged articular surface of a bone of the joint, wherein the alignment guide is custom fabricated for the patient based on imaging information of the joint and includes cannulations, each cannulation configured and dimensioned to receive a pin;
positioning a cutting guide having a guide surface, the positioning of the cutting guide based on at least two pins; and
cutting at least a portion of the articular surface of the bone of the joint by moving a cutting tool along a guide surface of the cutting guide.

Abstract
Imaging of a left or right joint is performed preoperatively, and an alignment guide and a custom cutting guide are formed based on the imaging. The alignment guide includes cannulations into which pins are placed. The cutting guide is then aligned using the pins, and bone of the joint is cut, using the guide, in preparation for an implant operative to replace a portion of the joint. The cutting guide is provided with one or more slots or surfaces to aid in aligning a cutting instrument. The alignment guide or cutting guide may be modified to correct for an existing joint problem, for example an incorrect alignment of the joint. The alignment guide or cutting guide may be formed with polymeric material.
