I had a total knee replacement 2 to 3 tears ago on my right knee.  After surgery and for over a week that leg looked like the after math of a severe meeting with a baseball bat.  I have never seen that before.  I have had over 12 operations ending in 1999 with a total knee on the Left knee and never did it look like that.  During recovery of the Right Knee things went very well and very quickly, compared to how long it took on my left knee.  In fact range of motion that returned to the right knee was greater and faster then for my left knee.  All seemed to be going very good but over the last year things have been getting worse.  1. range of motion is decreasing not only in the knee but up at the hip as well.  I can not cross my leg without helping it and then just barely and it hurts like hell from the knee to the hip with the hip hurting the most.  2.  The longer I stand or am on my feet the more my leg swells from the toes to the knee. Primarily on the right leg but also some on the left.  No I do not have diabeatis.  As for exercise I have to walk everywere I go as I do not have transportation and have been walking for close on to three years.
Naturally I am having all the other assorted pains to go along with this to include back pain which from time to time becomes so bad as to keep me awake at nights.  What is really surprising at times is pain in the right knee joint, and I mean right in the middle where the bone has been removed and the artifical joint now resides, when that starts it is really sharp and painful.
What is causing all of this?  Is it possible that after the operation not enough blood vessels on the return circuit were able to reheal so there is a delay in that circulation that causes the swelling and in turn the other problems?  If so how can I correct this?  Walking/exercise only seems to be making it worse, and I doubt that staying off my feet well do any good, so I am at a loss.  What do you think?  You can email me at maddad1947@att.net thsnk you.
