I have removed my frames on Nov last year. It has been 8 months and my right knee still hurts when I fully extend it. Also, I can't do squat even with low weight, it hurts on the way up when it gets nearly extended. It also feels uncomfortable lose sometimes. Does anyone experience what I am experiencing rright now. My left knee is in perfect condition but the right one is bad. I'm afraid I might have to live with chronic knee pain even for the rest of my life.
