Abstract
A prosthetic bearing element having a bearing surface is made from an ultra-high molecular weight polyethylene with a molecular weight greater than 1,000,000 with a multi-axially molecular orientation. From tests which have been applied to such material, it has been found that the wear rate is lowered and preferably the direction of one of said axial molecular orientations extends parallel with or along the length of the bearing surface.
