OUR BEST OFF-THE-SHELF KNEE BRACE CUSTOMIZED FOR SKIERS
The DonJoy Armor Knee Brace – Ski Version is soon to be discontinued. The Armor Knee with Fourcepoint Hinge is a good alternative with updated features to protect the ACL, MCL or Meniscus for skiiers. Select the Armor Knee Brace with Short Calf and Armor Hinge if you are looking to purchase the brace to be worn with ski boots. Shop the alternative DonJoy Armor for Skiing here.
The DonJoy Armor knee brace is the brace to use if you are an extremely active individual or athlete who suffers from an ACL, MCL, or PCL instability or injury. The Armor brace is one of the strongest and most supportive braces in our line of DonJoy bracing.
Since skiing knee injuries are so common, DonJoy created a version of the Armor knee brace just for skiers. The DonJoy Ski Armor is similar to Standard Armor knee brace with a short calf culf, but also includes a Medial Ski Deflector along the medial or inner hinged of the knee brace. This deflector prevents the medial (inner) hinge from “hooking up” with the other brace or knee. This feature is only available with the Ski Armor Knee Brace.
The DonJoy Ski Armor is recommended when two armor braces are worn at the same time. If only one brace is to be worn, the DonJoy Short Armor Knee Brace is recommended. The Ski Armor is 15" in length (short calf) to accommodate ski boots and other high calf boots.
The DonJoy Armor knee brace for skiers is used to treat or prevent the following injuries:
This brace is best for skiers or snowboarders who suffer from…
- Moderate to severe ACL or PCL instabilities
- ACL/PCL combined instabilities (CI)
- Recovery from ACL or PCL reconstructions
- MCL or LCL instabilities
- Hyperextension
Product Features…and the benefits you’ll experience!
- Available in ACL, PCL, and CI Versions
You get to choose the brace that is right for your injury, which means your knee will get the proper support where you need it most. - Four-Points of Leverage Dynamic System
This patented technology was developed to reduce the strain on the ACL by distributing the load placed on the ligament via four points. Click here to learn exactly how the Four-Points of Leverage works. - Medial Ski Deflector
Keeps you safe on the slope by preventing the middle hinge from “getting hooked up” with other braces or knee. - Adjustable Extension Resistance
The Hinge enables you to set the flexion angles (25˚, 35˚ (factory setting), 45˚, 55˚, or 65˚) based on your condition or point of recovery. This puts you in control where the degree of tension stops. - Custom Frame and Swiveling Strap Tabs

All the benefits of a lightweight and low profile knee brace. - Anti-migration Supra Condyle Pad

Product Questions
I blew out my left ACL (no reconstruction) and have been using a brace since the 1980s. One of the elastic straps broke on my old brace so I'm trying to decide whether to fix my brace or get a new one.
I'd like something economical, comfortable and lightweight. I want a brace that prevents hyperextension and provides side to side support. I prefer adjustable straps rather than sleeve type brace. I'd also like to stay in the $200 price range.
What knee brace do you suggest and why?
My only concern is that the knee brace will not protect against contact damage. Only a rigid brace will address that for you while still providing support.
Take a look at the DonJoy Armor Knee Brace – Ski Version for example. A rigid knee brace like this will provide more protection for activities like skiing.

I'm also confused about the need for deflectors ONLY when you're skiing with two braces. When you're skiing, there will be snow pants over the braces, thus preventing them from "tangling". The only exception would be if you are racing and wearing a racing suit. Or, I suppose, late-April skiing for people immune to cold who might not want to wear snowpants then (I do!).
But if you're wearing two non-ski braces for other sports that also use the forcepoint hinge (and thus are presumably subject to the same level of tangling), wouldn't you also want deflectors on the hinges to prevent said tangling? Especially since it may tangle with your knee, never mind the other brace/hinge?
Please. some clarification would be most appreciated.
The only distinguishing feature that separates the DonJoy Armor Knee Brace with Standard Hinge and the DonJoy Armor Knee Brace – Ski Version is the Medial Ski Deflectors.
The hinges on the DonJoy Armor Knee Brace with Standard Hinge is a low profile hinge, however if you'd like the deflectors without having to sacrifice the length of the brace, I'd recommend the DonJoy Armor Knee Brace with FourcePoint Hinge, as the hinge on the brace features deflectors as well.
The only change from a Standard Armor and the SKI Armor is that the SKI features a Medial Ski Deflector along the medial or inner hinged of the knee brace. This deflector prevents the medial (inner) hinge from “hooking up” with another brace. Not very necessary unless you're wearing braces on each leg.
You can order a DonJoy FullForce and simply select short calf in your options to achieve the same shorter brace length of the Armor SKI.
Either the Don Joy Armor Knee Brace will work or the Don Joy Defiance. With the Armor you will need to order the stops and have them installed by a medical professional or DME Coordinator, we can not send the stops to you. The Defiance is our custom Brace and the stops can be installed when we make the brace. Either brace should be ordered though one of our sales reps instead of BetterBraces. To find you local sales rep please follw this link or copy and past it on your browser.
