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 the Defiance III, Defiance, Armor, Female Fource, 4TITUDE and Legend braces. - 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.

- 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.
