With my TKR I was never informed I could have an allergy to the bone cement. Directly after surgery I was vomiting with a BP of 73/40. My knee was red all over, burning hot, and the pain was worse than before surgery. After three years surgeon thought I could be allergic to the nickel in the titanium replacement. Upon realizing my surgeon was considering a revision my primary physician referred me to an allergist for metal and resin testing. My results were being allergic to the bone cement. It has been a nightmare.
