Hello, I am new to this site and not. Even sure I am in the right group. I have a rather unusual situation in that I had a TKR 2 years ago and it was a total success. It corrected the arthritis in my other knee also as I was walking more steadily. Only thing is that I’m afraid that I have done something to upset the balance. A couple of weeks ago I started having pain in the inside of both knees and even more worrysome is that my replaced knee now has the stiffness that it had post surgery ( though not quite as bad, but still bothersome.) I know I overdid it with a 2 hour walk/hike a few weeks ago that had a various surfaces to walk on. I could tell that I was overdoing it and I was! Dr sent me doe X-rays and ultrasound on both knees. Not sure what it will show? Perhaps I should try MFR therapy. I will ask my doctor. Thanks!
