Four Points of Leverage Design:
The Four Points of Leverage combine to successfully apply a net differential posterior force, or constant force to the tibia, which reduces the instability in the ACL. This Four Points of Leverage design is used on all high end Donjoy knee brace designs.
- Point 1 Anterior: The first point of leverage is the anterior thigh cuff. It acts as a point for rotating the femur anteriorly.
- Point 2 Posterior: The second point of leverage is the posterior calf cuff. It acts as a point for rotating the tibia posteriorly.
- Point 3 Posterior: The third point of leverage is a posterior thigh strap, which is applied while drawing the hinge bars posteriorly on the knee.
- Point 4 Anterior: Incorporating the fourth point generates the crucial opposing force. By tightening and affixing the anterior tibial strap, the hinge is drawn into proper position, and the tibia is rotated posteriorly.
Available Colors: Black
Available Accessories:
- Patella/Shin Impact Guard- protects the patella and shin from direct blows.
- Sports Cover- goes on over the outside of the brace for added protection.
- Full Extension Stop- allows the brace to be locked in full extension.
- Brace Bag- A convenient bag for carrying the ACL brace.
- Neoprene Strap Suspension Kit- two neoprene straps that wrap around the brace over the thigh and calf to improve brace suspension. Highly recommended.
- Tru-Pull Advanced Attachment (TPAA) - This accessory piece provides additional support and symptomatic pain relief for patellofemoral dysfunction, including lateral mal-tracking, subluxation/dislocation & patellar tendonitis. The TPAA is an elastomeric pull device that provides a strong dynamic pull on the patella when the knee moves into extension. Choose from these 3 sizes according to knee brace size:
