Performance & Lifestyle
Armor FourcePoint ™
Unparalleled strength, reliability and proven ACL protection
Knee Ligament Bracing
Armor FourcePoint™
Unparalleled strength, reliability and proven ACL protection
The new Armor FourcePoint™ design combines a strong lightweight aircraft quality aluminium frame and the first low profile FourcePoint™ hinge with a protective steel outer plate.
By combining 2 patented DonJoy technologies, the 4-Points-of-Leverage™ and FourcePoint™ hinge technology , the new Armor FourcePoint™ provides one of the most powerful clinically-proven solutions to protect the ACL.
USER PROFILE • Contact and extreme sports • Highly active lifestyles
indications • Moderate to severe ACL, LCL and MCL injuries • Prophylactic ligament protection
FEATURES & BENEFITS
2
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. 1
FOURCEPOINT ™ HINGE TECHNOLOGY Knee 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.
Point of Leverage 1 The femur is anchored by a cuff placed at the top of the anterior thigh.

Resistance engages in last 25° of extension
Point of Leverage 2 The tibia is anchored by a cuff placed at the
bottom of the posterior calf.
Point of Leverage 3 A strap across the back of the lower thigh pushes the femur anteriorly.

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. 3
Point of Leverage 4 A strap placed on the anterior tibia applies an active constant load to prevent anterior tibial translation.
