Orthopaedic surgical instrument system for implanting a prosthetic patella component and method of use

An orthopaedic surgical system, comprising:

• a dome patella component configured to selectively engage a surgically prepared end of a patient's patella, the dome patella component including a convex, curved posterior surface,
• an anatomic patella component configured to selectively engage a surgically prepared end of a patient's patella, the anatomic patella component includes a body, a medial peak extending posteriorly from the body, and a lateral peak extending posteriorly from the body, the medial peak and the lateral peak cooperating to define a posterior surface of the anatomic patella component,
• a clamp comprising a retaining socket and a connector, the retaining socket and the connector being movable relative to one another,
• a compression socket configured to be selectively secured to the connector of the clamp, the compression socket having a receptacle defined in an anterior surface,
• a dome compressible base configured to be selectively received in the receptacle of the compression socket, the dome compressible base having an anterior surface shaped to conform to the posterior surface of the dome patella component, and
• an anatomic compressible base configured to be selectively received in the receptacle of the compression socket, the anatomic compressible base having an anterior surface shaped to conform to the posterior surface of the anatomic patella component.

A method of performing an orthopaedic surgical procedure on a patella of a patient, comprising:

• resecting the patella of the patient to produce a generally planar resected patellar surface,
• selecting a patella component from a group comprising a dome patella component and an anatomic patella component,
• selecting, from a plurality of compressible bases having differently-shaped anterior surfaces from each other, a compressible base having an anterior surface shaped to correspond to the selected patella component,
• positioning the compressible base into contact with the selected patella component, and
• operating an instrument to press the compressible base against the patella component and secure the patella component to the resected patellar surface of the patient.
