The REFLECTION^◊ Cemented Acetabular Component uses design features provided to maximize stability and durability in cemented acetabular cups. The outer surface of the cup is designed to improve the bond strength of the PE-cement-bone interface. The cup exterior is ridged in the radial direction and grooved in the polar direction. This design incorporates cement-thickness equalizing pods and a continuous flange that provides a uniform thickness of cement around the cup to even the load transfer to the cement and bone. With the extended flange, eccentric cup placement is prevented. The flange also increases cement intrusion pressure and penetration into cancellous bone during cup insertion. The polar grooves increase torque resistance by creating an interlock between the cement and cup. The grooves, ridges, and cement-equalizing pods have been designed to reduce the risk of cup loosening. A wire marker along the cup equator is a reference for radiographic cup orientation and wear measurement. The REFLECTION^◊ Cemented Acetabular Component is available in 3 mm outer diameter increments with inner diameters of 22, 28 or 32 mm.

The articulating surface of the polyethylene cup has distinctive design features for stability of the hip joint. Because the natural abduction angle of the acetabulum is about 60°, the positioned cup is usually precipitous which can cause superoposter dislocation of the femoral head component. In order to prevent dislocation, the cup has to be positioned at a more horizontal angle and the cup will be exposed outside of the bony acetabulum, particularly superoposteriorly. To avoid these problems, the articulating surface of the polyethylene cup is angled 20° toward the horizontal plane. This provides more coverage on the superoposterior aspect while keeping the center of hip rotation the same as the geometric center of the outer shell. The resulting abduction face angle of the polyethylene cup is a stable 40°.
