Disclosed herein are systems and methods of patella preparation. A method of patella preparation includes creating a patellar coordinate system utilizing key boney landmarks of a patella on a virtual model of an unresected patella. The method can further include defining a resection plane at a predetermined implant thickness and aligning the resection plane with the patellar coordinate system. Implant selection can be finalized on the resection plane to meet predetermined tolerances. A navigated patella clamp with a tracker and stylus can then be used to intraoperatively resect the patella and locate the implant.
