Abstract

A method for aligning a resection guide relative to a patient's bone has applications during arthroplasty. An alignment guide is coupled to a patient's bone, to which there is coupled a resection guide. The resection guide is positioned along a transactional path and a plurality of rotational paths by manipulation of the alignment guide, thereby providing three degrees of freedom of manipulation over infinitely adjustable ranges.
