I just had a knee surgery in Dec/14. Then my knee got infected somehow, so they had to open me up. Apparently, they cleaned it up, and they closed me. In late May, I had a wire sticking out on the back of my knee. When I called the secretary, she told me that s impossible, it must be a cist! I told her I can tell, what is a wire looks like. Then it brock through my skin, and when she made an appointment for the doctor, I handed over the wire, what looked like, was broken off from somewhere. The doctor looked at it, and told me, he never heard that before, even dough he does operations for more then 25 Years. So I had to go back, they opened me up, and he found the other part of the wire, and changed his story, saying, it was part of the knee replacement. Nobody, I talked to heard, that wire is involved with that kind of operation.
