I tried to point the sharp edge out to the ortho, but he kind of ignored me. At the end of the appointment, I talked about it again and he said that possibly it was scarring that had formed on top of the knee cap? He said he couldn't feel it (of course not, he didn't bother to spend the time to do so...) and that on the x-ray it looked fine. Of course the x-rays were from November and I couldn't feel the peg through my knee cap then, it's only been about the last few weeks that I could feel it.
Come to find out, the orthopedic I went to see on Monday had talked to my original ortho at a conference they went to a few weeks ago, so he based his evaluation on what my original ortho said.
I'm going to be going to one in a few weeks that has NO connection to either of these (except that they all practice in Maine.)
