Donjoy Armor FourcePoint

The Donjoy Armor FourcePoint takes protection to the next level with a hinge designed to provide protection where your knee is most vulnerable.  The FourcePoint hinge reduces the speed of your knee straightening out into full extension during the last 25 degrees of motion - where you're most at risk for tearing your anterior cruciate ligament.  Also new on the Donjoy Armor FourcePoint is the addition of an improved strap system that attaches to the inside of the frame for closer fit against your leg.  The frame design remains the same as the standard model delivering the patented Four Points of Leverage to provide complete protection for low to high contact sports.  The T6061 aluminum frame is both lightweight and strong enough to provide even the largest of athletes the level of protection required for high level sports participation.  By reducing the shock to your knee just before straightening out, the Donjoy Armor FourcePoint knee brace gives athletes and patients the highest degree of protection available today.  The brace is ideally suited for recovery from an ACL reconstruction or for returning back to full sports activity.

How Does The FourcePoint Hinge Work?

The FourcePoint hinge is designed to slow down your knee as you straighten it during the last 25 degrees of extension.  Think of it like a rubber band becoming more taught on the inside of the hinge.  The hinge box features a "on/off" switch which will turn the FourcePoint completely off if desired.  The hinge also comes with three settings that increase the amount of pounds of resistance supplied by the hinge:  the first setting equals 2 lbs, the second setting adds two more pound for a total of 4 lbs, and the third setting adds two more pounds again for a total of 6 lbs of resistance.  The hinge can supply these three levels of resistance through the last 25 degrees of extension through a flick of a switch. The brace is shipped with a 10 degree extension stop in the hinge box which can be taken out if desired so the Donjoy Armor FourcePoint will actually engage at 35 degrees out unless the extension stop is removed.  Because the hinge places a force posteriorly towards the back of the knee, it places an increased load on the posterior cruciate ligament, and therefore should NOT be used by patients with PCL injuries.

Donjoy Armor FourcePoint Knee Brace Features:

• Low profile FourcePoint hinge provides added ligament protection during the last 25 degrees of extension. Can be easily adjusted and disengaged altogether to function like a standard hinge if desired.
• Reduces the amount of time spent at or near the "at risk" position of 25 - 0 degrees full extension where the greatest amount of stress is placed on the ACL.
• New internally mounted strap buckles provide a closer fit against your leg.
• Shipped with a factory installed 10 degree extension stop in the hinge to prevent the knee from straightening fully out to decrease "shock" on the joint - can be easily removed if desired.
• T6061 aluminum frame for lightweight strength and durability.
• Features the patented Four Points of Leverage design clinically shown to reduce ACL strain by 50%.
• 6 month warranty on the soft goods/straps.
• 1 year warranty on the hinge.
• Right/left specific.
• Available in 7 seven sizes for an exact fit - see sizing chart tab.

features a new patented design to protect a newly reconstructed ACL (Anterior Cruciate Ligament) graft. Armor FourcePoint Technology was developed to further protect the ACL and enhance the Four Points of Leverage brace design. This Donjoy brace has a patented FourcePoint hinge designed to reduce the speed of the knee straightening out into full extension by applying incresed resistance in the last 25 degrees of motion.  This reduces extension shock and increases posterior tibial loads to provide enhanced knee protection during cutting and pivoting activities. The Donjoy Armor FourcePoint has three adjustment settings to vary the amount of resistance to meet the specification of the physician's protocol and the patient's comfort. The Armor FourcePoint is appropriate for patients returning to athletics after ACL surgery, or for anyone with a torn ligament needing to reduce buckling of the knee.During straightening out of the knee, the brace utilizes a spring mechanism in the hinge to apply gradually increasing resistance during the last 25 degrees of extension much like a tensioned rubber band. The resistance serves three critical roles:

• Reduces the time spent near full extension or in the "at risk" position.
• Increases the posterior load applied by the brace on the tibia to prevent anterior tibial translation, which reduces the chance of the knee buckling under pressure.
• Eliminates the extension shock felt when a patient extends into a 10 degree standard rigid stop!
