Features and Benefits
4-POINTS-OF-LEVERAGE™ DESIGN REDUCES ACL STRAIN
Through the 4-Points-of-Leverage™ rigid cuff and strap configuration, a posterior force is applied to the tibia, preventing anterior movement which stresses the ACL. Also, by reducing the anterior translation, the anterior lateral instability is reduced, allowing patients to improve their knee stability.
FOURCEPOINT™ HINGE TECHNOLOGYKnee flexion angles less than 60 degrees are considered “at risk” and contribute to ACL injuries.
The FourcePoint™ hinge technology increases the knee flexion angles thereby reducing the time spent in the ACL “at risk” positions. It enhances DonJoy’s 4-Points-of-Leverage System™ by dampening knee extension, and reducing shear forces at the knee.
The FourcePoint™ hinge uses a spring mechanism which engages in the last 25 degrees of extension and provides resistance during knee extension
LO PRO HINGE WITH STEEL OUTER PLATE
The low profile FourcePoint™ hinge features a new, sleek, protective steel outer plate. This makes it the thinnest yet toughest hinge available, able to withstand the impacts of contact or extreme sports.
