This state-of-the-art prosthetic knee provides lightweight true variable cadence, unequaled function and durability for the active to extremely active, above knee amputee. Designed as a 4-bar linkage, the instantaneous center of rotation is functionally located superior and posterior to the axis of the knee to enhance voluntary control, safety and energy consumption. The graphite composite fiber construction offers a weight-to-strength ratio that performs better than that of the strongest alloys. The internal structure is composed of a sophisticated pneumatic cylinder with full adjustability to provide variable cadence with an optimum gait while providing the highest degree of cosmesis.
