Rationale for the posterior-stabilized rotating-platform knee.
The nonposterior-stabilized mobile-bearing knee and the posterior-stabilized fixed-bearing design have been successfully used for the past three decades. Lessons learned from their use have culminated in the design of a posteior-stabilized mobile-bearing knee that incorporates beneficial features of both. The posterior-stabilized mobile-bearing knee is aimed at addressing polyethylene wear issues related to the fixed-bearing design, and improve upon stability and range of motion typical of nonposterior-stabilized mobile-bearing knee designs.
