I am so very sorry for what you are going through. Had TKR almost 7 mths ago. Problems too, but I work the heck out of it to keep from getting scar tissue. Its still swollen and feels like it moves the wrong direction and a doc here said he thought the implant was to large as I am petite. I think he is right. My surgeon keeps saying "Its fine" so I have seen two others for second opinons. One doc on a recent trip to Mayo....but I had to fight to get to see the ortho I wanted and that will be the one who does my other knee....not staying in my state and letting them screw up the other knee! I had a surgeon friend tell me the "won't see you for a year, its still healing" line is because most states have 1 year statute of limitations if the patient has to have other surgeries due to first not being done correctly. I talk to many others who have had TKR and are back out playing tennis in 6 mths and others who tell me horror stories. It all comes down to you, the patient, not accepting their excuses and being a tenacious advocate for yourself. I would not be walking today, if I hadn't refused the 15 surgeons excuses, "Oh you are in pieces after your surgery and none of us know how to put you back together again. Sorry but you will have to live in a wheelchair." My response was, "oh no I won't because I'm going to find a surgeon who knows how to put the pieces back together again!" And, thank the Lord I did find two ortho trauma surgeons at Mayo who had ideas of how to do it and, even tho the said the odds were stacked against me, they agreed to give me a chance to get my life back again. We had many hurdles to climb, but I refused to give up because I knew I would walk, hike, swim, travel and take care of myself again. Don't give up, keep researching to find a doc who might have other ideas and can help you. Good luck friend.
