KneeBinding - new ski binding

A new ski binding, "KneeBinding", is introduced recently, claim to protect your knees and ACL injury.

KneeBinding claimed they offer a unique system that allows the binding to release laterally (side to side) at the heel, and it is this specific feature which is believed to offer the ACL protection in an ACL vulnerable fall situation.

Just have to wait for the feedbacks from the users.

How is this different from the LOOK turnable heel binding? Do you know Mike?

How is this different from the LOOK turnable heel binding? Do you know Mike?
I was advised it is similar to the Look turntable binding.

Please refer to the following article which compared Kneebinding with other bindings, incl. Look Turntable.
http://www.wildsnow.com/863/kneebind...eyond-helmets/

I quote: "KneeBinding ski bindings are different from Look and all other turntable bindings because KneeBinding provides lateral heel release, while all turntable bindings do not allow any boot to release laterally 'through' the side-lugs of the turntables. It is impossible for any boot to pass through the side lugs on all turntables."

Actually, Marker Rotomat heel was one of the original turntable heel piece designs, much favoured by the pros. But, in the 1970s, they lost market share to the step-in binding designs from Tyrolia, Salomon and Look - who had their own variant of the turntable heel.

In my opinion, Kneebinding might do a good job in protecting the ligament in one specific type of fall and it will do that better than some other bindings in the market. There are other types of falls that the Kneebinding is either the same as any other binding or in some cases worse than other bindings. Have you seen (or heard) anyone using this binding on the slope if it is as good as they claimed?

1. I am surprised if there is no other binding that releases side ways from the heels. It does not seem to be such a difficult engineering feat.

2. If you look at this video again carefully:

http://www.kneebinding.com/Content09...Final_2D_M.swf

This binding does not seem to be able to release side ways with the heel going to the right. Check it out.

Although the video only shows the heel releasing to the left, it does say "sideways" (at about 48 sec). The heel release design looks similar to the turntable design (in principle) to me.

But look closely at the hardware, there is no 'opening' on the left side

So, there is going to be a "left" hand binding and a "right" hand binding ?

Hi - I'm John Springer-Miller, Chairman of KneeBinding. I thought I'd clear some things up and also answer any questions you might have.

First, this is not a turntable binding. Turntables provided a controlled rotation point under the heel of the boot that facilitates the lateral toe (twist) release. This release mechanism is part of what has been preventing broken legs in alpine bindings for 40 years. All alpine bindings have a lateral toe release (with or without a turntable) that operate the same way and produce the same benefit. KneeBinding, of course, also provides this kind of release.

But KneeBinding is the only binding on the planet that provides a lateral HEEL release - wherein a pivot point also exists under the TOE. A turntable allows the toe to come out sideways. KneeBindings also allow the heel to come out sideways. Picture a turntable binding, and you'll quickly see that the side lugs/bars absolutely prevent any kind of lateral heel release.

But lateral heel release - allowing the heel to escape the binding directly sideways - is the only proven way to mitigate knee injuries on skis. Most knee injuries (including 75% of all ACL injuries) on skis occur because your hips and knees are bent and your foot is pulled straight sideways to the outside. You can try this at home - sit down (hips and knees bent) and try to pull your foot sideways to the outside. Your leg can't move that way. If you catch an inside edge when your hips and knees are bent, it will pull your foot sideways - often with great force. This rips your knee apart. This is the classic "phantom foot" injury mechanism on skis.

Bow - your leg DOES move the other way. For example, you can put your right foot on your left knee. But it can't bend to the outside. Our lateral heel only releases in one direction because the injury can only occur in one direction. This is one of several reasons we do not have the kind of pre-release issues often associated with ordinary bindings.

One more comment - the so-called "diagonal" binding is also of NO help when it comes to knee injuries. Diagonal mechanisms must release upward before they release sideways. Since almost all knee injuries occur when you are "falling" backwards, these bindings cannot, and do not, release.

I hope this helps!
John

John

Thanks for the clarification.

Most appreciated if you could clarify the following question :

It appeared that your binding does not seem to be able to release side ways with the heel going to the right (ie. outside), we guessed it is a design in order to achieve retention. Does that mean there is going to be a "left" hand binding and a "right" hand binding

According to the respond from a Jonathan Shefftz, I quote:
"the binding is indeed asymmetrical, in that each pair has a dedicated Left & Right binding, so that heel unit releases horizontally only to the inside, i.e., medially. If a skier were to inadvertently swap Left/Right skis, then any safety advantage would be eliminated, plus the binding might very well be highly prone to prerelease."

Left/Right with KneeBindings

JSM 4/6

If the skier were to put the skis on the wrong feet, they would no longer provide the additional safety features to mitigate knee injuries. However, any additional risk of unwanted release would be slight. It might, for example, be like a skier who should be set to a DIN of 8 skiing at a DIN of 7 - and only in relation to the lateral heel release. Retention is very, very good on this release mechanism, as the force required to injure one's knee is so great.

Generally, KneeBindings have little to no pre-release issues when compared with most ordinary bindings.

I read about Kneebinding about a year ago. The original inventor has left the company but he sounded really knowledgeable in the industry and the product. He said he brought the Kneebinding in the market and perfected it with modifications. I loved to got the modified Kneebinding from him but did not have the chance...

One more thought...

JSM 4/6

In effect, putting the skis on the wrong feet would cause them to behave much like ordinary bindings.

However, it is not easy to put them on the wrong feet. The toe lifters are intuitively shaped like shoes - or boots. People often compare it to putting on their boots. How often do you even try to put your boots on the wrong feet? Never. That's because they are shaped like your feet. So are KneeBindings.
