I had my knee replacement at the New England Baptist in Boston MA. Before the surgeon would consent to do the surgery, a form had to be filled out concerning an allergy to nickel. I always had problems with pierced earrings (ears becoming red and swollen) so I wrote that down on the form. He had me to to a specialized place that did allergy testing for metals and the bone cement that is used. The bone cement test came out fine, but the nickel allergy readings came out very high. The surgeon ordered the knee replacement from a place called “Smith and Nephew”. I don’t know anything about this manufacturer but I know that the replacement was free from nickel and metal. I think that it’s very important to have those metal allergy tests done before you consent to a replacement. MaryAnn from Boston

Facilities like the Mayo Clinic (Cleveland Clinic, etc.) are wonderful, especially in diagnosing weird conditions. But...when it comes to finding the best surgeon for a particular situation, that often is not some one at Mayo. You will find a consistently higher level of care at Mayo than any other local facility but not necessarily the best particular specialist for a specific condition.

My knee surgeon uses a robot (CORI) and an implant made of oxinium:

I don't know whether that combo meets your requirements. If so, there are probably a number of surgeons out there doing both.

So I would recommend doing some research.
