FourcePoint™

Keeping patients out of the “at risk” positions...

Our patented DonJoy® FourcePoint technology is designed to react during leg extension. It utilizes a spring mechanism in the hinge to apply gradually increasing resistance during the last 25° of extension.


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

• Eliminates the extension shock felt when a patient extends into a 10? standard rigid stop!
