I can really relate to what you’re going through! It’s been 2 years since my TKR and I thought if one more doctor looked at me, shrugged their shoulders and said, “I don’t know what the problem is,” I’d lose my mind. It was that or I was told the TKR failed and I needed to start over. The thought of doing that gave me so much anxiety that I had decided to just live with the fact I was in more pain than before I had the surgery. That is until my knee started locking. I finally (after seeing 5 different doctors) found someone who suggested the spacer my original doctor used was too thin. Not one of the other doctors ever suggested that as a possibility. Finally hope! Meeting with the surgeon in two weeks to discuss moving forward with the spacer replacement.
