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.
