Drill burr and method for performing holes in subchondral bone to promote cartilage repair

A drill burr for performing holes in subchondral bone to promote cartilage repair comprising:

• a drilling head;
• and
• a neck connected to the drilling head, a stop positioned at a specific axial distance from the drilling head on the neck, the specific axial distance corresponding to a desired depth between a base of debrided cartilage and a subchondral bone marrow compartment, and a connector portion adapted to connect the drill burr to a drill;
• whereby an abutment between the stop and the base of debrided cartilage during drilling enables a hole of the desired depth to be performed.
