question: Hi I fell onto my left knee one year after a TKR, one year on still painful, hurts to walk downstairs and up. Had x rays and bone scans. Doctors have so far said they can find nothing wrong, Upon requesting my x ray results and bone scan results, the diagnosis was mild synovitis. This was not discussed with me at all, is there any cure, will it get better. I have been unable to play tennis now for 2 years and think that I will never get back to playing. What do you think.
