Abstract
A method for implanting a one-piece hybrid tibial tray component of a knee replacement prosthesis is disclosed. The method includes cutting an upper end of a tibia to accommodate the shape of the hybrid tibial tray and then punch fitting a tibial baseplate template having an imprint into the tibia. Next, cement is applied to the peripheral surface and the hybrid tibial tray is pressed down into the upper end of the tibia. Also, a temporary partition may be included, with the temporary barrier forming a barrier between the central area of the tibia and the peripheral area of the tibia.
