I need advice on free exercise ideas, but I have a unique problem. Aside from 2 kinds of arthritis in my knees and hips, I pulled a good one when I went for my 2nd fill. When I stepped up to get on the gurney, my right knee popped (loud enough to echo in the room), and I had severe pain. The next day my ortho diagnosed a partially torn ACL. I'm now in a custom brace, but warned to watch every step-they don't want to do a total knee on a 50-yr.old. So now I'm stuck-I was banded 2-12-09, and have only lost 26 lb. HELP!!!
