6H25 Polycentric Pneumatic Knee Joint

Polycentric pneumatic knee joint is intended for patients with moderate and high activity level, unilateral or bilateral transfemoral amputations at any level including the knee joint disarticulation and weight up to 125 kg.

Pneumatic swing phase control with flexion / extension adjustment allows good adaption to changes in walking speed up to 6 km/h.

Polycentric design of knee ensures increased security in the stance phase and geometric shortening of the prosthesis in the swing phase.

Center of rotation of knee joint is located in the forefoot area that together with polycentric design ensures extra security for users.

Knee joint has an additional simple and convenient adjustment of the security in stance phase for users with different activity level — from high for the patients with low activity up to the standard for active patients.
