Ive seen them more elaborate than that but simpler is better if it works.
Plus, I agree you might not be a good candidate for TKA today. But you are a tough old bugger and that trumps much.
Some general info for anyone interested. The best knee guys do three or four a day a couple of days a week and they are pretty good. That said, I would want to be first or second that day. The best way to find a good knee guy is find a couple of physical therapists who will talk to you about who gets the best results. I acknowledge this is not easy but is worth the effort.
