Nulty,
Get well soon, I will enjoy your posts here. I feel for you, some twemnty-five years a go I blew up my left knee. The doctors drained all kinds of nasty stuff out and did some orthoscopic surgery to it. I had crutches, but found them too hard to deal with. Walked on it right away and kept up my exercise routine, and my work was a lot of exercise back then. Doc pitched a real fit when I told her what I was doing. After the pictures were taken, she calmed down. My muscles were in good condition and kept my knee more stable than I could have done with the wrap and crutches. All healed well, except that the knee advises me of bad weather about two days in advance... Now that I am old, I am sure I could not get away with that approach.
I hope yours heals quickly and in better shape than it was before.
