    My LTKR is scheduled for May 15, but I had some concerns about metal sensitivity so I had the patch test done. It came back with some sensitivities, so my OS suggested a blood test. Just received the results and it showed a mild reactive to several different metals. My question is at what level should I be concerned? The test has 4 different levels. Normal 0-2, Mild reactive 2-4, Reactive 4-6, High reactive 6 and above.

    Since you showed some reaction, it would be wise to discuss this with your surgeon and with the doctor who performed the test for you. I would be concerned with any level of sensitivity. But, by "concerned" I mean that you need to find out exactly what those test results mean for you with a joint replacement. Each of us is different in our reactions (or lack of them) to metals. That information is something best obtained from your medical team. Good for you for having this all checked out before surgery, though!

    Well, after speaking with a different OS and my allergist, we have decided to postpone my surgery until we can find a replacement that will work.

    There are implants that should be safe for you.

    This article talks about some of them:
    Allergies: Metal allergies and knee replacements

    Do let us know what you and your surgeon decide, won't you?

    @Celle I will post on here after my initial meeting with a new OS. The problem is I test reactive to nickel, titanium, zirconium and possibly cobalt. I'm not sure where this leaves me, besides up the creek, without the proverbial paddle.

    I have a surgery date of July 17, but OS is still undecided as to which implant he's going to be using.

    You'll be fine. There are knee devices that are entirely coated with ceramic which are especially made for people with allergies. The AS-Advanced coating is one.

    Alternatively, Biolox do ceramic coated implants with the option of an all plastic tibial part instead.

    Thank you for the information. The AS-Advanced coated is one he is considering, but I don't think he mentioned the Biolox one. I will be sure to pass on this info.
