Abstract
A tibial support structure includes a platform portion and a medullary portion that are monolithically formed as a single piece. The medullary and platform portions of the augment component are adapted to accommodate and mechanically attach to a tibial baseplate, and are individually shaped and sized to replace damaged bone stock both within the tibia, as well at the tibial proximal surface. The monolithic formation of the tibial support structure provides a strong and stable foundation for a tibial baseplate and facilitates restoration of the anatomic joint line, even where substantial resections of the proximal tibia have been made. The tibial support structure may be made of a bone-ingrowth material which facilitates preservation and rebuilding of the proximal tibia after implantation, while also preserving the restored joint line by allowing revision surgeries to be performed without removal of the tibial support structure.
