Armor Knee Brace - Ski Version

100% of 100

Attention Medicare Patients

Offers the same protection as the Armor brace, with an additional Medial Ski Deflector on the inner hinge that makes the brace safe for skiing.


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
    Get a perfect fit by molding the brace to your knee, as well as enhance the fit and suspension of the brace with the swiveling strap tabs.
  • Aircraft Aluminum Frame

    Your knee brace will stay in place.
  • Calf Pinch Guard
    Provides a smooth transition between boot and calf cuff. This is an add-on accessory that is purchased separately.
  • Impact Guard
    Protects the shin and knee against blunt blows, as well as prevents you from ripping pants or uniforms. This is an add-on accessory that is purchased separately.
