Causes and prevention of acl injury in downhill skiing

that was the title of my term paper for an athletic therapy class this semester. based on peer reviewed journal articles only so it's pretty credible. if you want a copy I'll send you one but here are the main points:
-acl injury rate has increased 280% in the last 30 years, though ankle and tibial fractures have decreased 90% in the same timeframe.
causes:
- changes in equipment: new shaped skis cause higher ski to snow angles, which put the forces on different areas of the leg and knee. result- more strain on the acl
- changes in technique: with new equipment comes a new turning technique, more carving than skidding turns, uses different muscles, result- more force on acl
- poor skiing ability: 59% of all acl injuries happen to intermediate skiers. likely because they are overconfident and try things they aren't ready to do, result: more falls = more acl injuries
- gender: women more prone to acl tears due to hormones, smaller acl size, smaller and differently shaped femoral notches, alignment, hyperextension of the knee joint. result: guys are lucky.
prevention:
- education: showing a video on ski safety, how to test your own bindings, warmup, etc. reduced injury by 11%. result: video should be shown in all ski buses, resort daylodges, etc.
- fitness training: a study showed with a specialized weights, flexibility, jumping etc program acl injury rate could be reduced by 1/3.
- professional binding adjustment: having your bindings professionally adjusted and TESTED (handheld torque measuring device) can reduce acl injury rate by 7%.
yep so thats it. I thought it was an interesting topic. if you want more info I have tons, just ask.

danke, do you know of any supplements you can take orally that increase the strength or elasticity of tendons and ligiments?

Oddly enough, some random basic research I did started to suggest that longer tails increased the risk of ACL injuries. Centermount=longer tails.
Bahahaha... or, you could call it the 'elitist snob' cult. Anyways, my family already owns a country club, so no thanks.

also the ski boot has been changed quite a bit too. they used to not come up as much on the leg causing more tib and fib breaks. but since the ski boot has been brought up taller its next weakest point is the ligaments in the knee. so rather then saying its the ski i would agree more with it being the boot.

ice_is_scary: sorry i don't know much about supplements. last semester i took a nutrition class but the prof was all against them and basically said they don't work. also because they're not drugs the industry is totally unregulated and most of the time they contain things they dont' list on the bottle. if you want to take anything i'd get as much credible info as possible (ie not the dude trying to sell them to you) and then make your decision.
jib_this: yup I mentioned that in my paper, this was just a quick summary.
astomp: yeah boots and bindings that release a lot more consistently is the major cause of increase of acl injuries in the last 30 years, but in the last 10 or so years it's because of shaped skis.

Errgh, ligament injuries blow. Long recovery. My friend did her research paper for Biomechanics of Human Movement on ACL injuries. She found that women were much more suseptible because of the Q angle created by their hips. The bottom line, the best prevention for injury is to improve joint strength - ie: Do knee strengthening exercises to strengthen the joint and put less wear on the ligaments.

shapped skiis are the biggest culprit, they just love to turn and ski racers have way more knee dammage now with the shorter shapped ski's (Boots have been high since the late 60's, they are not a big issue)
