Abstract
A plurality of polymer layers are stacked together and subjected to a consolidation operation to generate an orthopaedic bearing component (18). Each layer is formed by longitudinally extending polymer fibers that are placed or woven together to define a predetermined orientation of the fibers. The consolidation operation fuses the layers together while at the same time retaining the predetermined orientation of the fibres. The component may be a tibial bearing plate for a knee implant. The orientation of fibers parallel to the direction of sliding movement between the bearing plate (18) and the femoral component (12) of the implant is believed to reduce friction between the components.
