A patella resection assembly comprises a handle, slide member and two claw members. The slide member is movably mounted on the handle and includes two diverging arms. Inner edges of the diverging arms contact outer edges of the claw members so that distal movement of the slide member causes the claw members to move toward each other and close around a patella. The claw members and slide member have teeth for grasping the patella as the claw members move together. The claw members also have flat co-planar surfaces for guiding the path of a saw blade during resection of the patella.

Patella resection assembly

A method of surgically preparing a patella for implantation of a patella prosthetic component is disclosed.

Patella orthopaedic surgical method

An orthopaedic surgical instrument that includes a patella resection guide is disclosed. The patella resection guide includes a body having a substantially planar upper surface that defines a patella cutting guide surface and a first jaw having a first tooth, and a second jaw positioned opposite the first jaw. The second jaw is movable relative to the first jaw and includes a second tooth extending toward the first tooth that defines an axis along which the second jaw is moveable relative to the first jaw. The patella cutting guide surface defines a resection plane that extends through a patient's patella when the patella is positioned between the first jaw and the second jaw.
