What about the wear particles?
The wear process caused by everyday life, produces small particles. In bearings with the same surfaces on each side, such as ceramic-on-ceramic or metal-on-metal, the particles may come from either surface, while bearings with a poly acetablular liner only generate particles of poly. The poly particles are so large that they cannot be digested easily. They tend to accumulate around the joint, and are associated with some hips loosening after many years because of a reaction to those wear particles.
