Description Overview The S.T.A.R.® Ankle system includes three functional components, and a set of customized accessory instruments that are used in the surgical procedure. The three principal components of the prosthesis are: • A metal tibial component with titanium plasma spray coating; • An ultra high molecular weight polyethylene mobile bearing; and • A metal talar component with titanium plasma spray coating. The mobile bearing articulates on the tibial and talar metal implant surfaces, as shown in the photograph of the three components of the S.T.A.R.® Ankle system below: Tibial Plate Mobile Bearing Talar Component The S.T.A.R.® Ankle is designed to replace a portion of the tibial and talar components of the normal ankle joint, while preserving range of motion as much as possible. There are two bearing surfaces in the S.T.A.R.® Ankle: (1) the interface between the upper side of the mobile bearing and the facing surface of the tibial plate, and (2) the interface between the lower surface of the mobile bearing and the facing surface of the talar component. The tibial plate has one flat surface and one surface with two raised cylindrical barrels oriented in the anterior/posterior direction. The upper flat surface of the mobile bearing slides against the flat surface of the tibial plate. The projecting cylinders of the tibial plate serve to fix the device to bone at the distal tibia. The lower surface of the mobile bearing is concave, fitting against the convex upper surface of the talar component. 1
