Abstract
Disclosed is a method of performing surgery to resect the patella for the purpose of installation of a patellar prosthesis, along with instruments used in such surgery. The instruments include a combined clamping device and reaming guide which when clamped about the patella provides a guide for reaming the surface thereof as well as a limit stop device designed to prevent reaming the patella too deeply. The instruments also include a reaming device designed to ream an annulus of material from the patella, leaving a central raised portion for fixation of a patellar prosthesis.
