As a pathologist I have examined thousands of knee replacement specimens in my career and I have notice a later stage of osteoarthritis – “terminal joint”.  Eventually bone on bone articulation creates eburnation – polished bone as hard as marble and I have destroyed many a bone saw attempting to cut this petrous bone.  Articulating surfaces become smooth and hard as porcelain. All you need is a little lubricant – hyaluronic acid works just fine for terminal joints.  It’s like waxing your skis.
