Hi, Mary. Gee, you have my sympathy re the knee pain. I think it's good that you are going to see the MD in a week or so.
I also have been dealing with quite limited ROM - less than 90 degree flexion, stiffness as well as pain in my left knee that is now 3½yrs post original TKR (which was a botched job - see my older posts) and 3yrs post the TKR revision. I was to the point of accepting that this was just how it was going to be for the rest of my life (sigh). The revisionist surgeon diagnosed me post-op with severe arthrofibrosis and said that, because of this, I was not a candidate for ANY further surgery on that knee, and was not a candidate for any future joint replacement surgery. As a person with RA, this was especially bad news.
Last month, due to a generalized flare of the RA, I was put on a 3 week course of prednisone - 30mg/day to start with then tapering down 20 mg/wk, and 10 mg/wk the third week. By the 10th day, I had NO pain in that knee, I could walk better and longer, and there was no swelling or heat in the joint. It was amazing! My symptoms have, for the most part, come back after finishing the prednisone a few weeks ago.
However, this experience has spurred me to make an apt with the revisionist to ask him what this all means. Perhaps in the 2½yrs since he last saw me he has become aware of some new treatment for my situation. Or perhaps he'll tell me that my synovial tissue has grown back and is staying inflamed due to the RA. I have been on Humira weekly, 20 mg MTX weekly and 300 mg of Celebrex daily which has not helped the pain in that knee in all the time I have been on it but has helped other joints that have flared up. Only the higher dose of Prednisone has made a difference with the TKR knee.
My appt is on Sept. 4th and I will post here any info I get that could be helpful to you. I also feel strongly that my doctor should see the patients that have not had good results over the long term - it may influence how he treats and advises other patients in the future with similar problems. I would bet that they generally operate under the assumption of "no news is good news".
