Should I Choose Short or Standard Length?

There are two length options available for the Full Force Knee Brace. These options are:

  • Short: Includes a shorter calf area that stops further up your calf. This is ideal for those using their brace with ski boots, skates, or other equipment that requires space on the calf and shin.
  • Standard: Includes a standard calf section that goes further down the calf. This may provide a more secure feel, but both length options will provide the same high level of support.

Can I Wear the Donjoy Full Force Knee Brace on Either Leg?

To ensure optimal fit and comfort, the Donjoy Full Force Knee Brace has been designed specifically for the left and the right leg. You can select the option you need from the drop-down menu at the top of the page.

What Is the Four-Points-of-Leverage System?

Donjoy Knee Brace Technology
The Four Points of Leverage are spread out across the brace for better balance

Through the rigid cuff and strap configuration made by the Four Points of Leverage, a posterior force is applied to the tibia to prevent anterior movement. This is clinically-proven to significantly reduce ACL strain and provide a constant dynamic load on the joint for improved stability and support.

What Is FourcePoint Hinge Technology?

The Full Force Knee Brace combines two clinically proven Donjoy technologies in one brilliantly performing brace. Using Four-Points-of-Leverage stabilises the ligament 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.

Passive vs. Dynamic Braces

There are two differing approaches to the design of a knee brace: passive and dynamic supports. Passive brace designs don’t actively address instabilities, which allows the knee to move before the brace can take effect and therefore results in a greater chance of injury.

Conversely, Donjoy’s dynamic Four-Points-of-Leverage design continually addresses instabilities at all times, whether you're running, jumping or standing. This prevents injuries while also allowing you to maintain an active lifestyle. Learn more about FourcePoint and other Donjoy Knee Brace technologies by reading our blog!

Standard Polycentric vs. FourcePoint

Most functional braces incorporate standard polycentric hinges that connect the thigh and calf frames through multi-centred pivot points. This attempts to mimic the knee’s natural movements.

On the other hand, Donjoy has taken the hinge design and ACT protection to another level with its patented FourcePoint technology. FourcePoint is the only hinge design that’s clinically proven to protect the ACL by reducing the amount of time spent in the "at-risk" position. That’s confidence every athlete can count on!

Does the Full Force Knee Brace Have Spring Loaded Support?

The Full Force Knee Brace is designed to stabilise the ligament and significantly reduce ACL strain by dampening knee-joint extensions, which increases flexion angles and reduces anterior shear forces on the tibia. It does not, however, feature spring loaded support.

How Do I Care for the Donjoy Full Force Knee Brace?

To maintain good levels of hygiene, we recommend cleaning the Donjoy Full Force Knee Brace regularly. The liners and condyle pads can be hand washed in cool water (30°C/86°F) using mild soap, and air dried. Do not heat dry liners or pads.
