I was religious in going to PT 3 times a week for 6 months. Dr. and PT therapists were shocked at my recovery according to flexibility and strength, but sadly I'm still at a 7 when I go up and down (stairs, sitting on and getting up from the toilet, chairs, etc.). I can walk and hike (downhill and uphill hurt but are manageable), play tennis, etc. but the flexing kills me at a certain angle. It's worse than before surgery. At 12 months an MRI and X-rays were taken and they show no inflammation or rejection of materials or slippage of any kind. Dr. was stumped and her only suggestion was to go to another PT person. My gut tells me this is not PT related. Out of desperation, I used a Shaman who told me I have little to no synovial fluid and that is what's causing the pain. He put me on Herbal tea and I'm wearing a copper sleeve. That was 1 month ago and so far I've had no relief. I was supposed to have the L knee done but that is definitely on hold as the two knees now feel exactly the same.
