What metal do doctors use in knee replacement surgery?

Question

Me and my spouse don't agree on this. I say stainless steel or maybe titanium. My other half says silver.

Answer 1

Silver is way too soft of a metal!  It wouldn't last.

Definitely titanium (strong, light, expensive) or steel (strong, heavy, cheaper).

Answer 2

My new knee is stainless steel and titanium. No silver.

Answer 3

My boss just had a knee replacement surgery and his is made of a titanium alloy.  It was supposed to have been some kind of state-of-the-art device that was not proven yet, but he is doing quite well so far.  I hope that helps.

Answer 4

It's titanium. They don't use steel because it's not hypoallergenic like titanium is, and it weighs less.

Answer 5

I believe it's titanium - it's strong and light. Silver would be far too expensive.
