@george12345 What an difficult situation to find yourself in, revision is no fun. In 2011 my implants were recalled - not my knee, but my hips. They were recalled due to danger of metal poisoning. In my case I was young (under 65), my pain was always at a 5 or higher, and I had symptoms from the metallosis, so the decision to revise was easy.

Based on your description, I would have a LONG talk with a surgeon who does a lot of revisions about the risks versus benefits of revision.

One thing to consider - chronic inflammation (as evidenced by the swelling & pain) is very hard on your entire body, and could cause you to develop other problems, or age faster. If you are generally active and in good health, you might want to avoid that scenario.

It might help to keep a journal for a month, recording pain and swelling levels each day, and noting the days' activities, to see how often it really is flaring, and maybe even whether it is getting worse.

Will the manufacturer cover the costs of revision and rehab, including any help you might need during that time?
