ABSTRACT:
An improved patella clamp apparatus includes a scissor-like instrument frame having a pair of handles at one end portion. A patella holder and drill collet have gripping surfaces for holding a patient's patella therebetween during preparation for implantation of a prosthesis. The collet has arcuate slots for accepting the vertical ridge of the patella. A reamer or cutting instrument cuts a circular recess into the posterior face of the patella. The collet is supported by the frame and positioned opposite the elevator. The collet accepts a depth stop for referencing the posterior aspect of the patella. The collet provides a bore that supports a reamer or drill for forming the circular recess in the patella posterior surface.
