Donjoy 4-Point-Of-Leverage System

The Donjoy 4Titude Knee Support uses Donjoy’s four-points-of-leverage system, which can be found in the majority of Donjoy’s top knee braces. This significantly reduces ACL strain and provides a constant dynamic load on the knee. The four points of leverage are as follows:

• Point One (Anterior): The first point of leverage is the anterior thigh cuff. This acts as a point for rotating the femur anteriorly.

• Point Two (Posterior): The second point of leverage is the posterior calf cuff. This acts as a point for rotating the tibia posteriorly.

• Point Three (Posterior): The third point of leverage is a posterior thigh strap. This is applied while drawing the hinge bars posteriorly on the knee.

• Point Four (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.
