Abstract

A knee prosthetic for implantation includes a mobile rotatable posterior stabilized (PS) post. The mobile PS post may rotate or distract superiorly relative to a tibial component. The mobile PS post may rotate with the femur after implantation, at least for a selected distance. Various exterior shapes of the mobile PS post and/or a bore formed in the tibial component may be selected to limit the amount of rotation. Various materials may be chosen to form the mobile PS post depending upon desired qualities.
