It's been 6 months now since my knee replacement. I've been trying to avoid discussing the ongoing shit show of health problems this surgery seems to have caused me, but over the last week I've learned some things that I think anyone who might ever be in the same boat should know. It appears I am very much allergic to my knee implant. The symptoms were mild at first but over time with prolonged exposure my body has just gone crazy rejecting it. Mostly in the form of itchiness and severe rashes amongst some other more subtle things. My little heart freak out in January may also be tied to it.
I'm going through a myriad of tests right now to figure out exactly which metals and glues I'm allergic to and which I'm not. It sounds like it's most likely a nickel or cobalt reaction though. I hadn't been exposed much to that in the past so I didn't know, but I found out afterward that my sister is allergic to nickel so it's likely I am too. After they do all that testing I'll probably be getting a knee re-replacement, this time one made with metals and glues that I'm not allergic to. Total nightmare scenario. Most people won't end up in this boat until they are in their 50's or 60's, but keep this in mind to save yourself a lot of trouble when/if you end up needing a replacement. There is testing that can be done in advance, but since only 10-15% of the population is allergic, they don't usually check before hand (crazy to me). I think part of the reason is the fact that it sometimes takes prolonged exposure before the reaction gets severe. Anyway, something to think about.
