Damn, Wayne!
I was always amazed by those implants...and the one in the recall is metal-on-metal bearing surfaces in the ball/socket - You'd think, "that can't be good" (?).
You would think that they would make one component out of metal and the other out of, say, ceramic. I'm sure there are just a whole bunch of engineering considerations and conflicts involved with a piece of hardware being inside of a human body....crazy stuff.
Well maybe they can put a Zerk fitting on the side of your hip, Wayne?
