Mobile bearing total knee arthroplasties are a class of prostheses in which a plastic bearing is free to move on the tibial baseplate. This type of prosthesis was introduced in the late ’70s with the attempt of reducing wear, through highly conforming surface, and removing the interfaces constraint in order to allow the bearing to rotate and slide. Both these targets relate with the possibility of using these prostheses in young and active patients. Another goal of the mobile prostheses is to reproduce a kinematics similar to the normal knee physiology. In this paper the different types of these prostheses are analyzed and personal experience with the Meniscal Bearing Knee prosthesis is reported.
