Jewels, your story is one of bravery & determined battle against your disabilities. Is there a silicon implant that might create a cushion between the bone-against-bone in your knee? I see that you are better, and this is wonderful news! Your resolution to be as independent and free of, for example, your chair foot rests, is an inspiration to us all. (((((((((((((Jewels))))))))))))))) Hope your foot is much better, and, for goodness sake, don't fall!
