ABSTRACT:
An adjustable depth patella recessing guide and method for guiding a cutting tool to recess the posterior surface of a patella. The guide includes a body having a first end for engaging the posterior surface of the patella, having a second end, and having a bore extending between the first and second ends for allowing the cutting tool to pass therethrough. A depth gauge is mounted within the bore of the body for movement in a direction between the first and second ends of the body. The depth gauge includes a stop for stopping the cutting tool. A lock mechanism is provided for locking the depth gauge to the body. The method includes the steps of clamping the body of the adjustable depth patella recessing guide to the posterior surface of the patella; placing the distal end of the cutting tool against the posterior surface of the body; then ascertaining the position of the cutting tool relative to the body; then locking the depth gauge to the body so that the depth gauge will stop the cutting tool a certain distance past the ascertained position of the cutting tool relative to the body; and then inserting the cutting tool into the posterior surface of the patella until stopped by the depth gauge.
