I was told that the next time that I had a knee surgery, it was going to be a replacement. That was 3 years ago, and with the way medicine progresses, I am wanting to look at options. My knee is locking and shifting, not a lot, but enough. I can walk without much pain, but bending and squatting is tough. I heard about a new procedure called Mako(sp) surgery, that basically resurfaces the joint so it will track straight. Anyone hear of it, or know about it?
