## Indications for use
The subject Avon' Patellar Component is intended to be used with the Avon' Patello-Femoral Joint Replacement in replacement of the patello-femoral joint. The subject Avon" patellar component is a modification of the Kinemax® All Polyethylene Patellar Component. The Avon™ Patellar Component has been modified to include the addition of a blend radius on the medial aspect of the patella. This blend is designed to reduce the contact stress of the patella on the patello-femoral component. The rest of the design features of the Avon patellar component are identical to that of the previous released Kinemax® All Polyethylene Patellar Component. The Avon " Patello-femoral Joint Prosthesis is intended to be used in cemented patellofemoral arthroplasty in patients with degenerative arthritis in the distal femur and patella, patients with a history of patellar dislocation or patella fracture, or patients with failed previous surgery (arthroscopy, tibial tubercle elevation, lateral release) where pain, deformity or dysfunction persists. The Avon™ Patellar Component and the Avon" Patello-femoral Joint Prosthesis are intended for use with bone cement.
