hi...i have some info to offer, re: your request for knee brace sources.
please let me begin, by saying: I AM NOT A DOCTOR! please be sure TO SEE
YOUR DOCTOR BEFORE BUYING/TRYING A NEW BRACE!!!!
sorry about the yelling...i don't want to mess up anyone's knees!
i was using a lenox hill knee brace...yes, it was sturdy, but it was
heavy, and also restrictive to a normal jumping motion. i went to my
orthopedist, and told him that i wanted him to rebuild my knee, because i
was very uncomfortable playing with the lenox hill brace. he talked me
out of the surgery, and suggested that i try getting fitted for a cti-2
brace. i was doubtful, but i agreed.
having now spent three plus months with the brace, in sand, grass, and
indoor play, i can say that the cti-2 brace is wonderful. i can't believe
how unobtrusive it is; i forget that i am wearing a brace most of the time.
the brace is very stable: carbon and titanium fibers that are woven
together and dunked in some sort of epoxy (at least that's what it looks
like to me!). it weighs only about 6-8 ounces, and it's very rugged.
i've only noticed one drawback: i get very strange tan lines on my bad leg.
good luck with your knee; i hope this info has helped.
