I am now 15 months post TKR, and I still have constant trouble. The bend in my knee stops at about 90 degrees, and it is like a cement block trying to bend it any further. I can walk for several miles, but if I walk more than that, it becomes even stiffer and painful. I recently went to a gym to try riding a stationary bike. That has caused me a world of trouble. It feels fine while I'm pedaling, but it really hurts and is very stiff later. My question is this...could the bike riding be breaking up scar tissue causing all of this pain? Or is that not a possibility - to break up scar tissue on your own? When I last saw the doctor last September, he said I probably am dealing with scar tissue. And then...see you in a year. Is there some sort of test that can be done to determine if this is indeed scar tissue or arthrofibrosis?
I constantly feel like a tight band is on my knee, above and to the side. It NEVER feels normal or good.
