I too have had my knee replaced twice. The first was with the chromium/cobalt alloy that contained nickel. Turns out my skin was not allergic to nickel but my blood was. They replaced it with a titanium implant but didn't check for allergic reactions to bone cement. After a second blood test after the surgery it turns out I'm allergic to bone cement particles. Still with swelling, pain and rashes after 2 years and 3 months since the first surgery. The doc says another revision would be risky due to potential bone loss. He is attending an orthopedic convention in Chicago in 2 weeks and will bring my case up to see if there is other possible treatment plans or surgical options.View Thread
