by whitewave » Jun 24, 2019 My knee isn’t better. It’s terrible. I’m in pain all the time. I’m severely allergic to titanium, et all. I won’t get a metal implant in my body and all ceramic are not FDA approved here, but they have been in use for years in Europe. So I’m going to try platelet rich plasma and stem cells (out of pocket, the largest quote was $11,000 for the Regenexx procedure). Obviously, I am especially grateful I can afford this to try with no guarantees of it working. In the meantime, my ortho surgeon has a partial ceramic non allergy part where the thigh bone part is made of zirconium, which is similar to titanium. I’m not happy and it’s a huge unknown if I would react to it or not. I’m also in contact with the ceramic parts rep in the USA and am picking her brain about a timetable for FDA approval here. At any rate, I got on Etsy and lo and behold, I found in The Netherlands a jeweler who will make me a 100% zirconium ladies band so I can wear it on my pointer finger for a while to see if I react. Will this prove or solve anything? I have no idea, but for $56 dollars I figured it was worth a shot. Without pricescope, this would never have occurred to me.
