Would you believe this story?

To me, that metal - on - metal had large friction, especially with the newest designs, it was clear from the old Sir Charnley studies in Leeds in 1950s published in his gold book. 

Anyway, when I looked at ceramic on ceramic joints, I also found evidence of increased friction.  Maybe ceramic debris is less toxic?

Please comment.  What can we do outside USA to improve the situation?
