Replying to ? - Asterisk Knee Braces - ? (Thanks)

Recently I was diagnosed with a pretty grim knee situation (severely damaged cartilage under my kneecap) - other than one very specific, very expensive operation that MIGHT help, the doc said its pretty much up to me how much pain I can bear relative to the sports I chose to enjoy.

Obviously, I want to ski.....

So I'm wondering if anybody here has experience with Asterisk Knee Braces, specifically their "Cell" model....If you've used them, how much did it help? what was your injury beforehand/at present? do them fit with ski boots (I happen to telemark...)

ANY information/reviews/advice would be much appreciated, seeing as the Cells run about 575/pair on eBay.

Thanks.
