Hi healthtalk. I'm sorry for what you went through. A few questions - do you think the nickel is from the metal prostheses? I thought those were made out of titanium. Or maybe there is nickel in titanium?

Second, even if there is nickel in the prostheses, how is it getting into your bloodstream? I think that would only happen if any of the metal prostheses used in the femur, tibia, and patella rubbed against each other. I didn't think that happened in a TKR. The metal does touch the polyethylene in the prostheses to replace the meniscus, and some in the patella, but I'm not aware of a TKR where these different pieces of metal rub against each other - the only way any metal would wear away and be present in your blood.

Just curious because I had both knees replaced in 2022 without incident. I worked very hard to achieve a successful outcome and had a terrific surgeon. I also know this is not everyone's experience.

Finally, when your surgery was redone, what metal was used in the new prostheses?

Thanks very much. I hope you're better.
