Had similar situation after initial TKR in Nov 2024. Surgeon insisted there was nothing wrong and to give it time. Within the first 3 months after the TKR, I was admitted back into the hospital with intractable pain and swelling. Again the surgeon said there was nothing wrong. I mentioned to the surgeon that it was my knee and body and I knew when something was not right. I sought out a second opinion and it was determined that the implant had not been balanced properly with the correct spacer. After 14 months in pain, I had attempted to have the implant correctly balanced without being explanted. The original manufacturer did not make the correct spacer needed to balance, so the implant was removed and a new correct sized implant from another manufacturer implanted. The first day post op after the revision, I was pain free. You have to be your own advocate. Some times the surgeons have an ego that is easily bruised and when a patient disagrees with them, they become dismissive. I speak from experience. I worked in healthcare for almost 50 years and have seen this even before I was a patient. Hang in there. It does get better once you get the correct surgeon.
