@gator1965 Something is definitely not right for you to be in so much pain for so long. If I recall correctly, the cause of the problem the woman I knew who had pain for two years was that it was from something in the extensions being too long. I really do not remember clearly but I know it was something like that. She did some research and found a top orthopedic surgeon and he was able to fix it. The new surgeon took the knee replacement out and put a whole new one in and she was fine.
