Mate blowing out my knees was the reason I stopped racing minis bout 6-7 years ago. Knee braces will definitely help protect your knees. I use Asterix Cell. I've heard the new ones don't stay put the way my old ones do. They fall down when you walk or some ****. Check out pods. They are pretty good. Just go try some on and see what suits. Although my cells are sooo adjustable and have been set for my knee shape exactly. I can even set them to open only to the point my legs will. (Stops hyperextention) and remember. Don't be a cheap ****, you get what you pay for. And a busted knee will cost you a lot more.
