I read what you wrote and wonder if it might apply to me. I’ve had 3 TKRs on the same knee in 2.5 years. The implants keep coming loose or moving. This is between two doctors, military and civilian. The 2nd one was implanted farther into the bone and the 3rd one, only the bottom implant was changed. I still have instability, pain and swelling . Doctor doesn’t know where to go and getting another 2nd opinion is impossible. No doctors will see me because of the two previous doctors and surgeries. I’ve had bone scans for infection, allergy test, fluid drawn and still no reason for the difficulties. Right now I’m being told there are no difficulties with the implants. They’re not loose but leg somewhat unstable with pain. Been using a cane for 3 years and leg has nerve pain since day one. Need help anyone
