Rearward twisting falls on skis are perfect to tear ACLs.  New innovations in binding seek to fix that, but the bindings are beat and would never keep a freestyle skier in them. 
feel lucky you're a guy, ladies are more than 6X as likely to tear an ACL skiing

I believe the technical reason is that too many skiers lock then pop when they should pop and lock.

Seriously though, high speeds with our legs being held in awkward angles by bindings when we crash.

ACL tears are almost always caused by hyperextension or twisting of the knee. And skiers have these long sticks strapped to our feet that make both hyperextension and twisting of the knee extremely easy.

I hate to tell you this but the newschoolers.com forum is not a valid source for a research project unless you're in elementary school

relax.  he is looking for some insight as to why it happens commonly in skiing.  I dont think he is looking to use NS as a source.

think about it, whats the joint that moves the most and takes the most impact while skiing? the knee. also, think of what happens if you catch your ski in the snow when you fall or something, your leg twists and there is a huge amount of pressure on your knee.

the ski acts as a lever on your knee. because the ski is so long when it catches and you fall it creates too much torque on the knee and your knee gets fucked up because it can't resist the forces

If you can't figure out why skiers are prone to knee injuries you should drop out of school and work at wendys because it is real fucking obvious.

because you tend to twist when you fall and have weight on your leg on skis and thats what causes an ACL to tear
