I am returning to Bonesmart after 9 years and looking forward to the informative and supportive community here. I am 68 and had a right THR back in April 2009. The new hip served me well until this summer when I had a few instances of instability in the joint. Then I started getting mild pain off and on. I had been doing light workouts in the gym twice a week and felt I was getting better and stronger but then something changed where the pain was worse and more persistent. An xray and MRI scan shows the prosthesis has loosened and I need a revision to replace at least the femoral prosthesis. I am anxious about this unexpected re-do. I have a ceramic-on-metal joint which I was hoping would serve me for the rest of my life. I have received little in the way of explanation for why the THR has loosened. "Maybe, wear and tear." "Bad luck." I have appointments with the local ortho practice where I had the primary THR with the surgeon who specializes in revisions. They do about 2 per week in this practice (that may include knee revisions, not sure). I also have an appointment with Dr. Brad Waddell at the Hospital for Special Surgery in NYC. If I like Waddell, I am inclined to go with him because our local hospital does not have the best rating and HSS has a top rating for orthopedics. He is a young surgeon, has been with HSS for a little over a year but already received an award as an outstanding clinician. He has done about 1200 total surgeries, including hips, knees, primary and revision. About half of those are revisions. Does anyone have any advice or tips for me as I navigate the pre-surgery maze of appointments and tests? I am on crutches at the moment. Not in a lot of pain but just wanting to keep full weight off of the THR leg.
