FullForce ACL Knee Brace

The DonJoy FullForce ACL Knee Brace represents the pinnacle of protective bracing technology, engineered for athletes who refuse to let an ACL injury sideline their ambitions. By integrating our most advanced and clinically-proven systems into a sleek, lightweight design, the FullForce delivers maximum security and confidence, allowing you to perform at your peak in any activity.

Revolutionary Hinge Technology: The Patented FourcePoint™ Hinge

• This is the core of the FullForce’s protective power. Unlike conventional hinges, the FourcePoint™ technology is clinically engineered to work in harmony with the body’s natural biomechanics.
• It dynamically translates harmful rotational and forward tibial forces—the primary causes of ACL strain and re-injury—away from the vulnerable graft or healing ligament.
• This proactive protection mechanism provides a level of security that is clinically proven, giving athletes the confidence to make sharp cuts, sudden stops, and powerful jumps without hesitation.

Proven Structural Foundation: The 4-Points-of-Leverage System™

• DonJoy’s legendary 4-Points-of-Leverage System forms the brace’s robust structural chassis, creating a stable environment for the knee joint.
• This system effectively controls the motion of the tibia relative to the femur by applying counter-forces at four critical points above and below the knee, effectively “unloading” the ACL.
• The synergy between this frame and the FourcePoint™ hinge creates a holistic protective system that is widely recognized as one of the most powerful solutions available for ACL protection and management.

Superior Athletic Design & Unmatched Comfort

• Exceptionally Lightweight & Low Profile: Crafted from strong, aircraft-grade aluminum, the FullForce provides maximum strength without the bulk. Its sleek design fits easily under clothing, making it the preferred choice for sports like football, soccer, basketball, and skiing.
• Internally Mounted Swiveling Strap Tabs: These innovative tabs pivot to accommodate the natural rotation of the leg during movement. This eliminates strap migration, prevents bunching, and ensures a secure, comfortable fit throughout the entire range of motion.
• Swooping Thigh Cuff Design: Specifically contoured to provide clearance for the inner thigh muscles, this design enhances comfort, reduces skin irritation, and allows for bilateral (both legs) brace use without interference.

Built for Every Athlete, Backed by a Guarantee

• The FullForce is designed for all activity levels—from the professional athlete competing at the highest level to the recreational enthusiast staying active on the weekend.
• It is the go-to prefabricated brace for anyone requiring definitive ACL protection without a custom brace price tag.
• The DonJoy Knee Guarantee Program™: An industry-first for prefabricated bracing, this program underscores our confidence in the product. It is backed by a robust 1-year warranty on the frame and hinges, ensuring your investment is protected.

In summary, the DonJoy FullForce ACL Knee Brace is not just a brace; it is a piece of high-performance athletic equipment. It combines clinically-proven protective technologies with an intelligently designed, comfortable chassis, empowering you to train harder, play stronger, and live more actively with complete peace of mind.
