Uh oh. Back up here. I just had a revision surgery (2nd one on same knee) because of severe Arthrofibrosis. 24 hrs later, had radiation on the knee - surgeon was honest - told me that medicine does not yet know how to deal with this internal scar tissue that forms after surgery - in some people. It's called Arthrofibrosis. An MRI can see it, as can those special CT scans that use a kind of dye. But, if you develop Arthrofibrosis, chances are, it will happen again. Please go to the I.A.A. site (International Arthrofibrosis Association.) There is also a supportive Facebook site, and a site called Bonesmart, where they give you good PT advice - only gentle slides several times a day - no pushing through pain. That just creates more inflammation. Please find out what your situation is before you repeat the surgery. I am hoping that the radiation will give me more range of motion, and we need to do PT for a full year before we know what our flexion will be. Seriously. It takes time for the inflammation to settle down. If you push while swollen, you only compound the problem. Please, please check out these sites.
