Hi Nunees2019, and welcome! My first TKR is going to be on August 13th, here in New Orleans. It's a little scary but I am hopeful that I may regain more use of that knee, with less pain, after recovery. Then when I have recovered enough, on to the other knee, for me anyway.Having my first total knee replacement on the left knee 19 August at Evans Army Hospital in Colorado Springs, CO
If you feel you'd like to have a more accurate test - which seems like a good idea - this is how:However, when I was a teenager, I could not wear 'cheap' earrings without my earlobes getting itchy, swollen, and hot. I did a 48 hour patch test this week, and nada, zip, zero response to anything on the patches - 35 of them. I don't know if I should trust the patch test being accurate. I surely don't want to go thru this TKR only to find that I really am allergic/sensitive to metals in my implant.
It sounds as if your surgeon is referring to the CeramTec knee.One of our partners, Aesculap, has a layered knee implant that has Zirconium nitride (a ceramic coating) as the top layer. It's called the Gold Knee and it has had success in people who have allergic reactions to some of the metals typically used in knees.
CeramTec also makes a ceramic knee but it is still involved in the FDA approval process. It is available in Europe and the UK.
