Systems including a provisional tibial prosthesis system are disclosed. The provisional system can include a tibial component, a base component, and a shim component. The tibial component can have a proximal surface and a distal surface, the distal surface can be configured to seat on a resected proximal surface of a tibia. The base component can have a proximal surface and can be configured to couple with the tibial component when disposed on the proximal surface thereof. The shim component can have a proximal surface and a distal surface. The proximal surface can be configured as an articulating surface sized and shaped to articulate with a femoral prosthesis and the distal surface can be configured to couple with the base component at the proximal surface thereof.

Bearing trial system

A punch assembly for preparing a tibia bone for a prosthesis includes a static component configured to be supported by the tibia bone and a dynamic component that includes a punch having a stem. The dynamic component is supported for movement relative to the static component along a generally arcuate path to prepare an aperture having an arcuate contour in the tibia bone. A method of preparing a tibial aperture for is also disclosed.
