I just saw this. I am a 51 year old female who has had 14 surgeries including both knees replaced twice. My most recent one in 7/11 is already loose and I am now back to wearing a brace. I'm seeing a specialist who is testing me for connective tissue disease and to see whether I have an infection. I'm awaiting all my test results but have already been told I may not be eligible for more surgeries because I have so much hardware in there that they would have to remove. Have you found a Doctor that deals with special cases? I, too, have developed hip and lower back pain but I don't have any pain in my knee. Good luck to you!View Thread
