The USTAR II tibial augment is a modular knee reconstruction component used when a patient has more bone resection. It works with the system’s femoral component, tibial baseplate, and tibial insert as part of a reconstructed knee prosthesis.
The broader system addresses substantial bone loss and deformity, including after failed joint replacement, tumor resection, or trauma. The augment adds a component option to the knee assembly for cases requiring additional reconstruction.
