What is a MUA? The 1st surgery October 2013 was to be a patella scrape, but the night before he changed to TKA. I was having redness, pain and swelling. In Feb 2015, I was told I was allergic to the metal, without being tested, so the metal was replaced with titanium. Still having pain, swelling, redness and now stiffness. The therapists made a game out of my care, as to trying to see who could get the best range out of my knee. Still having all the same symptoms so on May 2018, the third and final surgery, I was told, after the surgery that my TKA was loose and needed to be replaced. When I returned and told the doctor I was still in pain he yelled at me and told me I was a difficult patient and not to return. So, I am still in pain, can't bend my knee, swelling, bruising, fever, locking knee and near falls. I have a walker, cane and wheelchair. My quality of life is gone. I can't walk past a few yards, can only stand for 2-3 min. Can't play with my grandchildren, can't dance with my husband. I wake up at night when my knee locks with every turn or quick movement. I can take pain meds. The doctors I have seen 4 keeps telling me there isn't anything wrong with my knee, that it's basically in my head. Even with the noticeable swelling, fever and bruising.
