ABSTRACT:
A tibial trial assembly for evaluating the stability and kinematics of a tibial implant, particularly a mobile bearing implant, prior to committing to the final preparation of the proximal tibia is described. The tibial trail assembly includes a tray trial adapted to be secured onto a resected proximal end of a patient's tibia. An evaluation bullet is either adapted to removably fit into a configured recess in the trial tray, or is integral therewith. A trunnion on the evaluation bullet accepts a recess in a corresponding articular tibial insert trial. The tibial insert trial is thus received on the trunnion. Preferably, the evaluation bullet is removable from the trial tray such that the remaining assembly is used to locate and guide (orient) the instrument(s) that prepare the tibia for the final implant. Typically, this includes broaching, drilling, or punching through the opening in the trial tray/plate.
