Motocross Knee Brace Pack with Donjoy Armor Knee Brace

If you’ve injured your ACL and want to get back into motocross and other extreme sports, you need a knee brace that will provide the most robust support while standing up to all sorts of pressure. The Motocross Knee Brace Pack with Donjoy Armor Knee Brace includes the ultimate ACL knee brace, along with a hard plastic Impact Guard to absorb shock and an undergarment to keep your skin protected from rubbing and discomfort.

What’s Included in the Motocross Knee Brace Pack?

This pack includes everything you need to protect your knees in motocross and extreme sports. It includes:

  • 2 x Donjoy Armor Professional Knee Brace with Fourcepoint – For robust ACL support
  • 2 x Impact Guard for Donjoy Knee Braces – To protect the knee and shin from impact

How Can This Knee Support Pack Help with Motocross?

In motocross, as with most other extreme sports, your knees can face some serious impacts, which is the last thing you want if you’ve suffered an ACL injury or have recently undergone surgery. The Donjoy Armor will protect and support your ACL better than any other brace out there, while the Impact Guard will absorb shocks while shielding your shin from any impact. The Black Lycra Undergarment is another great addition, as it will keep you safe from friction and pinching.

What’s the Donjoy Armor Designed For?

The Donjoy Armor is the best brace to use for active people suffering from ACL instability or injury. This ACL knee support is particularly suited to treatment and protection of:

  • Moderate to severe ACL instability
  • Recovery from ACL reconstruction and surgery
  • MCL or LCL instability
  • Meniscus injury
  • Hyperextension prevention

What Is the Benefit of the Impact Guard?

The Impact Guard is an official Donjoy accessory that’s been specially designed for motorsports, providing a high degree of protection to your knee and shin. Made with a hard plastic shell and soft inner foam, it will absorb any shock from impacts, ensuring your knees stay protected in more ways than one.

How Does the Donjoy Armor with Fourcepoint Support the ACL?

The strongest and most supportive ACL brace around, the Donjoy Armor with Fourcepoint is a hinged knee brace using the Donjoy Fourcepoint hinge technology. The spring-loaded Fourcepoint hinges keep the hamstring in constant tension and take the pressure off the ACL using a “Four Points of Leverage” system. As the hamstring is attached to the tibia (or shin bone), the hamstring tension pulls the tibia back keeping it stable and almost entirely eliminating the chance of an ACL injury.

How Does the Fourcepoint Hinge Improve ACL Support?

While the Donjoy Armor is available without Fourcepoint technology, it’s the Fourcepoint hinge that really puts this brace at the top of the class in terms of ACL support. The brace works by limiting the time your knee is in an “at-risk” position, increasing the posterior load applied by the brace on the tibia when you reach a certain level of knee flexion. This dampens knee extension and reduces shear forces on the knee, all while improving your natural gait by applying increasing resistance until you reach a firm point during your natural movement.

Sizing Information

The Donjoy Armor with Fourcepoint Knee Brace is available in seven sizes and is suitable for men and women. To determine which size is right for you, you must measure the circumference of your thigh, knee, and calf, and then refer to the table below.

The thigh measurement is taken around the thigh 15cm (6″) above the knee cap. The knee center measurement is taken directly around the center of the knee cap. The calf measurement is taken around the calf 15cm (6″) below the knee cap.

What If My Measurements Fall Under Different Sizes?

If your measurements fall under different sizes (for example Medium for Thigh Circumference and Large for Knee Centre), we recommend you choose your size based on your Thigh Circumference measurement.

Which Size of Impact Guard and Undergarment Should I Choose?

You should select your Impact Guard and Lycra Undergarment in the same size as your Donjoy Armor Knee Brace. Unfortunately, these items are currently unavailable in Extra Small and XXX-Large sizes.

How Durable Is the Donjoy Armor?

Constructed from light aircraft-grade aluminum, the Donjoy Armour with Fourcepoint Knee Brace is exceptionally strong and lightweight and enables you to continue with any sporting activity. As this is the standard short calf version, the knee brace doesn’t interfere with either a ski or motocross boot and remains clear from the top of your boot.

What Is the Four Points of Leverage System?

As is mentioned above, the Donjoy Armor uses a “Four Points of Leverage System” to increase the posterior load on your tibia, thereby reducing the load on your ACL. These leverage points are labeled in the diagram below.
