Here's my take on it as an Eastern Cup level FIS racer... among  
people I know personally, at my level, this past season was the worst  
for injuries I've ever seen (almost all ACL, MCL, miniscus, or some  
combination thereof). While i think this might have been in part due  
to snow conditions (bumpy tracks, bare spots, etc.), there is also a  
lot to suggest modern equipment. from (endless) talks about world cup/ 
high level racing with coaches and other athletes, i think that there  
is a pretty substantial correlation between equipment and injuries. I  
don't have any hard numbers to back it up, but according to my coach  
(who has been coaching for 20-some years, and been a ski racer  
himself for most of his life):

knee injuries have increased dramatically at virtually every FIS  
level since the advent of shaped skis, especially in speed events,  
and especially among women. One of the most common ways to tear an  
ACL these days is in a speed event (super g/downhill) when coming  
into air "late" (behind teh course). I know from experience that this  
is not a good situation... you generally are not as well prepared to  
absorb the air as best you can when you enter in late, and then  
(worse) you can have to land on edge just to make the next gate. The  
problem is, with shaped skis & speeds approaching 90+ (world cuppers,  
the fastest i've been clocked is 76) if that ski lands on edge the  
right way it can carve way too quickly to control and you could have  
a torn ACL before you can do anything about it. In slalom this can  
happen when you get late & get "launched" the your ski, especially  
when you're in the back seat. According to my coach, several years  
ago, before FIS started raising minimum sidecuts & lengths, so many  
women world cuppers where injured in speed races as the result of  
shaped skis that they didn't even fill the quotas for some of the  
races towards the end of the season.

So again, I don't have any specific research to back up those claims,  
but both emperical evidence that i've seen and heard about, as well  
as my own experiences/sensations while skiing agree that more sidecut  
& more lift increase the chance of knee injury. Still shaped skis  
have definitely helped the sport too. the hard  part for FIS is to  
find the "middle" ground between injuries & performance.

that's my take at least
