Abstract: An orthopaedic reamer for cutting bone includes a rotatable shaft and a cutting head coupled with the shaft. The cutting head includes a distal face with a radius and a plurality of cutting teeth. Each cutting tooth includes a pair of opposed side walls extending from the distal face and a cutting edge extending between the side walls. Each cutting edge includes at least three adjoining segments. Each segment has a radius which is less than the radius of the distal face.

Abstract: An instrument for preparing a human patella for implanting a patellar prosthesis. A support member includes a quick-release base member mounted adjacent a first end of the support member. A reamer member is removably mounted on the quick-release base member. An attachment release member is resiliently mounted on the support member for movement into and out of engagement with the quick-release member and the reamer member. A stop member is adjustably mounted for limited movement on the support member to a plurality of calibrated positions for setting a controlled depth for movement of the reamer member.
