My MRI results came in Tuesday and my doc told me my left knee was basically destroyed. Miniscus is in pieces, bone on bone, severe arthritis and bone spurs. Plus ligament damage. I can feel it grinding and shifting when I walk. I'll be having it replaced in a month or two. Basically as soon as he can get me in. My wife had both of hers done last October three weeks apart. She has done amazingly well. The biggest thing I keep hearing is that you have to keep up with therapy or you will never get your full range of motion back.
