Replying to Preventative Knee braces

The other thread about braces got me thinking, what is everyones views on preventative knee braces? That is to say my knees are fine never been fucked up however acl/mcl tears seem to be the most common injury to skiers and are fairly serious. As much as  I am going to try to avoid hurting my knees it looks like a serious tear is pretty much inevitable for a serious skier. So with that said assuming price is no object (insurance would pay all but an insignificant copay), would you wear knee braces on healthy knees as a way of preventing injury, even if it only worked 15% of the times.
