Lightweight, High-Support Brace With Adjustable Hinge Technology For Enhanced Knee Ligament Protection

• Four-Points-of-Leverage: The brace provides enhanced stability through a four-point leverage system, which helps reduce strain on the knee ligaments, particularly the ACL. This system distributes pressure more effectively across the knee, improving both support and protection during movement.
• Adjustable Resistance: Offers three levels of adjustable resistance at 25-0, 35-10, and 45-20 degrees, allowing for customized support based on the user’s needs and activity level. These settings enhance control over flexion and extension, providing a more personalized and comfortable experience.
• FourcePoint Technology: Incorporates FourcePoint technology, which is specifically designed to reduce the strain on the ACL by encouraging a safer, more controlled range of motion. This innovative feature increases stability and protection during activities that put pressure on the knee.
• Flexion-Extension Control: Allows users to control and limit the range of motion in both flexion and extension. This feature is particularly beneficial during rehabilitation, as it can help prevent overextension or bending too far, reducing the risk of re-injury.
• Size Options: Available in 7 different sizes to accommodate a variety of body types and ensure an optimal fit for maximum effectiveness and comfort. A better fit can enhance both the stability and comfort of the brace.
• Contoured Frame Design: Features a contoured frame that conforms closely to the leg for a more comfortable and natural fit. This ergonomic design minimizes bulk while ensuring the brace stays securely in place.
• Durable Frame Material: Made from 6061 T6 aircraft aluminum, which is lightweight yet extremely strong, providing a robust and reliable frame that can endure heavy use. This material offers both protection and long-lasting durability.
• Warranty Coverage: Comes with 1-year warranty on the frame and hinges for assurance of quality and performance. Additionally, 6 months warranty on soft goods ensures coverage on padding and straps for added peace of mind.
• Anti-Migration Feature: Equipped with a standard anti-migration Supra Condylar Pad to keep the brace in place and prevent slipping during activities. This feature enhances stability and support by reducing unwanted movement.
• Stylish Design: The frame is finished in a Silver Vein color, which gives it a sleek, professional appearance. This design aspect adds an aesthetic appeal to a highly functional piece of support equipment.

How to fit a Donjoy Armor

Bend the knees to between 90-70 degrees either in a squatting position, or sat down so you can see down your shin; then measure around your thigh 6 inches up from the top of your kneecap. The circumference around the thigh at this point corresponds to the sizes below:

Size Chart	Thigh (cms)	Thigh (inches)
X Small	33-39	13-15.5
Small	39-47	15.5-18.5
Medium	47-53	18.5-21
Large	53-60	21-23.5
X Large	60-67	23.5-26.5
XX Large	67-75	26.5-29.5
XXX Large	75-82.5	29.5-32

Please note that the additional condyle pads are not included as standard. If you specifically require them added then please contact before ordering us to check.

What is the Donjoy Armor Hinged Knee Brace?

The Donjoy Armor Hinged Knee Brace is one of the most high level and supportive knee braces on the market. It is provides un-paralleled support to the cruciate ligaments in the knee. The Donjoy Armor forms a lightweight exoskeletal frame for the knee made from aircraft grade aluminium, which follow the contours of the calf and thigh.

One of the best features of the brace is Donjoy's unique Fourcepoint hinges, located either side of the knee. Unlike the conventional offloading gear hinge which connects the thigh and calf through a series of geared pivot points providing a stabilising force, whilst mimicking the knees movement. The Fourcepoint hinge is different, knees are most vulnerable to injury during the later stages of extension (straightening your leg) the Forcepoint hinge uses a spring mechanism to apply a gradually increasing resistance during extension, this dampens the movement preventing any sudden jerks on the joint, the best comparison is to a soft closing drawer in the kitchen the mechanism takes effect just in time to stop the draw slamming or in this case the knee becoming injured. You are also able to adjust the resistance level between 5 settings depending on your injury and activity level.

When to wear a Donjoy Armor knee brace?

Wearing a Donjoy Armor, will prevent all unnatural movement in the knee, whilst retaining a full range of natural movement. This means that it is suitable to wear for a large range of purposes, from day to day wear, to taking part in sports at a high level. It can be worn to stop unstable knees from hyper extending, twisting, or bowing (both laterally and / or medially).

The Donjoy Armor is extremely popular for use in snow sports such as skiing and snowboarding where ACL tears and ruptures are very common, other sports include motocross racing, walking, running and climbing. The only time the Armor will not be suitable is for contact sports due to the solid nature of the metal frame and the risk of injury to other players.

The Four Points Of Leverage

Donjoy apply their four points of leverage theory to the Armor to provide a constant force to the tibia, which reduces the instability in the ACL by removing load from the knee and dispersing it between the thigh and calf muscles. The four points are as follows:

• 1 - The anterior thigh cuff anchors the femur at the top of the anterior thigh.
• 2 - The posterior calf cuff anchors the tibia at the bottom of the posterior calf.
• 3 - The posterior thigh strap across the back of the lower thigh acts to push the femur forwards.
• 4 - The anterior calf strap provides the essential opposing force creating a constant active load on the tibia, preventing anterior tibial translation.
