A bearing assembly for a prosthetic joint has two bearing elements 4,6 connected by an integral linking element 8. The assembly is moulded as a block and then material is removed from between the bearings to create the linking element. Alternatively, a separate linking element may have its ends compression moulded into the bearing elements. Preferably, the linking element is flexible but resilient; it may be made from polyethylene or may be a fabric or polyester cord. A retaining bridge 50 may restrain movement of the linking element to prevent dislocation of the joint. Preferably the bearing assembly sits on a tibial plate 30 as part of a prosthetic knee joint.
