Ottobock 3R80 Knee Joint

The 3R60 is a polycentric knee joint. An intelligent miniature hydraulic system controls the pendulum movement of the lower prosthetic limb during the swing phase. This means that flexion and extension of the knee joint are dampened by corresponding movement resistance provided by the miniature hydraulics. The dampening characteristics of the hydraulics were precisely adapted to the needs of prosthesis wearers with a moderate activity level. In the stance phase, when the prosthesis bears the body weight while walking, what is known as the EBS unit of the 3R60 controls the flexion movement beginning at heel strike and the subsequent extension movement. This harmoniously dampened movement pattern in the stance phase is based on the natural model. The benefits include a more physiological gait pattern and a shock absorption effect when stepping down with the prosthesis, reducing the forces acting on the residual limb, pelvis and spine. Safety in the stance phase is also improved by preventing the unintentional, sudden buckling of the knee joint. This limited stance phase flexion allows the user to also walk down slopes up to approx. 10° step-over-step. Thanks to the multiaxial joint design of the 3R60 EBS, the prosthetic leg effectively shortens during the swing phase, reducing the risk of stumbling for the prosthesis wearer.
