Ideal applications include:
The DonJoy Armor knee brace with Fourcepoint hinge design combines two clinically-proven DonJoy technologies in one brilliantly performing brace. Our 4-Points-of-Leverage System provides ligament stability and significantly reduces ACL strain.DonJoy's FourcePoint hinge dampens knee joint extension, which increases flexion angles and reduces anterior shear forces on the tibia. The result - less strain on the ACL and a considerable decrease in the chance of injury. Together, these two technologies add up to ironclad confidence.
DonJoy Armor knee brace with Fourcepoint hinge is used to treat or prevent the following injuries:
- Moderate to severe ACL instabilities
- After ACL reconstruction surgery
- Hyperextension
Goals:
- Increase high impact activity;
- Delay knee surgery;
- Prevent stop shock syndrome;
- Decrease anti-inflammatory medications;
- Decrease pain symptoms associated with ACL injuries;
- Improve joint function;
- Provide maximum support and maximum stability
Features & Benefits:
- 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.
- FourcePoint Hinge Technology
Makes you less likely to suffer from an ACL injury because it reduces the amount of time your knee is in an “at risk position”, enhances the Four-Points of Leverage by increasing the posterior load applied by the brace on the tibia, and improves your natural gait by applying progressive resistance before reaching a firm end point during movement.
- Strong Aircraft Grade Aluminum Frame
You get the benefits of a lightweight and low profile knee brace that is also stronger, thicker, and more stable than the other lightweight knee braces on the market.
- 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
You get the benefits of a lightweight and low profile knee brace that is also stronger, thicker, and more stable than the other lightweight knee braces on the market.
- Anti-migration Supra Condyle Pad
Your knee brace will stay in place no matter how active you are.
- Calf Pinch Guard
Provides a smooth transition between boot and calf cuff so you’ll never pinch your calf again.
- Impact Guard
Protects the shin and knee against blunt blows, as well as prevents you from ripping pants or uniforms.

The difference is due to the fact that this brace comes equipped with Fourcepoint hinges.
The DonJoy Fourcepoint Hinge protects the ACL. The Fourcepoint Hinge enhances the DonJoy Four Points of Leverage system by damping knee joint extension, improving the brace's mechanical performance, and reducing knee shear forces. The Fourcepoint Hinge utilizes a spring mechanism to apply a gradually increasing amount of resistance during knee extension.
The resistance 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, and gives patients a more natural gait by applying progressive resistance before reaching a firm end point. The resistance can start at flexion angles between 25° and 65° and engages during the last 25° of extension prior to coming to a hard stop. Five different resistance levels are available to meet rehab protocol specifications and provide comfort. The resistance can be adjusted using the supplied allen wrench to modify the set screw placement. The same wrench can be used to turn the resistance completely off by simply flipping a switch.
Because the hamstring insertion angle increases and the quadriceps become mechanically disadvantaged as the knee becomes more flexed, anterior shear forces on the tibia and ACL strain are reduced. Therefore, athletes returning to sport after an ACL reconstruction who wear a DonJoy ACL brace equipped with Fourcepoint Hinges can protect themselves while engaging in activities involving the run-stop-jump task.
