I had my TKR on my left knee on 1/22. I am able to walk on my own, go up/down stairs and fulfill my PT schedule. I am still on Percocet/Advil. My issue other than the standard no sleep is my good knee. The only surgery my right knee ever had was a year ago January for a small meniscus tear. Since my surgery the right knee is making these awful grinding sounds, snapping and popping and a good amount of pain in the lower left quadrant of the knee. I am sure that favoring it all these years hasn't helped but this came out of the blue. Perhaps if it is localized osteoarthritis, I can get away with a Unicompartmental MIS down the road. I do have an Unloader brace. Any thoughts? Thank you. Wayne.
