Apparatus for reaming a patella

Abstract

An apparatus for reaming a patella includes a clamp for securing the patella and a reamer. The reamer includes a depth scale to indicate a depth to which the patella has been reamed. The clamp includes a pivoting collet to enable the clamp to stably secure different patellas having a variety of shapes and sizes. The stability of the collet is ensured by a plurality of prongs on the side contacting the patella, which are arranged to be equally spaced around the peak of the patella. Using this reaming apparatus, the depth to which the patella is reamed can be accurately determined. The reamed patella can then be fitted with a prosthesis to coordinate with a femoral prosthesis fitted on a resected femur and a tibial prosthesis fitted on a resected proximal end of a tibia to form a reconstructed knee joint which is substantially at anatomic level and has a proper degree of laxity in both flexion and extension.
