The wear and wear debris from rotating-platform mobile-bearing knees and fixed-bearing knees were compared in knee joint-simulator studies. The wear rate of the fixed-bearing knees was found to increase as the kinematics were increased because of an increase in internal-external rotation and an increase in anterorposterior (AP) translation. The wear rate of the rotating-platform mobile-bearing knees was found to be significantly lower than that of the fixed-bearing knees. The rotating-platform mobile-bearing knee was able to decouple the complex kinematics to pure rotation at the inferior tibial articulating surface and linear flexion-extension and AP sliding at the superior femoral articulating interface, substantially reducing cross-shear and wear. No difference was found in the wear debris between the rotating-platform and fixed-bearing knees. This resulted in a substantially reduced functional biological activity or osteolytic potential for the rotating-platform mobile-bearing knees due to the lower wear rates.
