Are look pivots/rossignol fks any safer than a normal binding?

I have never understood the "turntable" idea, is it suppose to decrease the chance of knee injury like a knee binding? Sorry if my question seems rhetorical but i'm actually confused. +K for good answers

The turntable allows your knee to pivot to avoid acl or mcl injuries, of course you can still injure such parts of your knee as you're spinning in the air and hitting rails all day. I do speak from experience though as I have broken my knee cap and needed a patellar tendon a year later, it was my fault though not the bindings', simply keep in mind that this binding can help prevent a knee injury but the possibility is always there

NO. The rotating heel allows for more elasticity which prevents pre-release and makes the bindings less likely to putt out. It does NOT help prevent ACL injuries. If you look at the heel, it is clear to see why this is the case. There is not a degree of release freedom in the heel. The boot will NOT release from the heel horizontally. The only binding on the market right now that actually has a horizontal degree of release freedom in the heel is the Knee binding.
Believe me; I just researched and wrote a 6500 word engineering research paper on the topic.

this exactly. the turn table offer greater elasticity and prevents pre releases so the din won't be cranked up super high.

This guy's got it spot on, although it is a common misconception that turntable bindings are 'safer' than other designs. Knee bindings are currently the only bindings on the market that can claim to be 'safer' than the competition.

Its all about the elasticity. Since the binding is more elastic you won't pre release as easy, meaning people are less likely to overtighten their DINs which opens them up to more injury.

That was quite impressive. Some of it was a bit over my head. I actually own a pair of knee binding but they are a bit heavy and not really catering to park and I know a ton of people are skiing park on pivots/fks, I think within the next 5 years bindings will be stock with ACL protection.

Thanks so much, that means a lot! And as far as the future of bindings go, I definitely hope that they ALL start to account for knee injuries. Now that knee binding has done it, it is only a matter of time before someone else does.

I see this is a super old thread but…

In your research, did you explore the idea that the turn table allows the foot to rotate on the axis of tib/fib vs the back of the boot on a toe release?

I always felt they strained my knee less than a more traditional heel.


I also acknowledge that strain and ACL tear are not the same having done both.

Cheers

Tyrolla protector bindings have now integrated the knee binding technology with the lateral releasing heel
