Polycentric Knee Joint 6Н01 is intended for patients with low and moderate activity. The joint is used in hip prostheses for patients with above the knee amputations, including transfemoral disarticulation. The kinematics of joint allows to achieve a functional shortening of the prosthesis in the swing phase.
Adjustable flexion — extension assist improves control of swing phase. Ball bearings used in the knee joint do not require maintenance and ensure high reliability and increasing resource of knee joint.

Single Axis Friction Knee Joint 6Н02 is intended for patients with low and moderate activity, unilateral and bilateral amputations or disorder of support function of retained lower limb.
At angles of flexion up to 15 ° the further flexion of joint is blocked under the load that provides a secure stance phase. The joint is fully released when unloaded, wherein the joint becomes movable again. There is an adjustable extension assist with weight 60 g.
Friction bearings of modern polymer material used in the knee joint provide the smoothness and compensate side play.

Polycentric Pneumatic Knee Joint 6Н23 is intended for patients with moderate activity level, unilateral or bilateral transfemoral amputations at any level with the exception of knee joint disarticulation. The Knee Joint 6Н23 provides pneumatic swing phase control and independent flexion / extension adjustment. The Joint 6Н23 is well adaptive to changes in walking tempo in the extended range speeds — from slow to rapid step without changing the initial settings.
Polycentric design ensures increased security in the stance phase and geometric shortening in the swing phase, increasing the distance from the base surface during swing phase that enhances the confidence of patient in the pros- thesis.

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.

Single Axis Pneumatic Knee Joint 6Н29 with weight activated stance control offers a safe and smooth gait for moderately and highly active users.
Pneumatic swing phase control with extension assist and independent flexion / extension adjustment may be set from regular to dynamic walking pace in the range up to 6 km/hour.
At the last 10° to full extension pneumatic damper has an additional feature that allows to reduce an angular rate and prevent an impact in extension phase. Design of the pneumatic damper provides stability of settings for the entire operating period.
Knee joint is equipped with a weight activated brake mechanism that provides a secure stance phase and can be totally released when the weight is transferred to the forefoot without lifting the hip thus saving energy for dynamic pace.

6H30 knee hydraulic joint is intended for patients with weight up to 125 kg unilateral or bilateral transfemoral amputation at any level including disarticulation in the knee joint. The knee joint is recommended for patients with a high level of activity — M3, M4 (without sport load).
The hydraulic knee joint is a monocentric joint with a rotary hydraulic system that controls the swing phase and provides a support in the stance phase due to high flexion resistance.
Walking down stairs and on inclines is effectively supported by the hydraulic system with closely approximating to the physiological gait pattern.
The damping level is controlled by the flexion and extension throttles that provides a comfortable walking experience at a wide range of speeds.
Flexion and extension resistance can be adjusted inde-pendently with ease.
If necessary, the extention assist can be increased by install-ing an additional spring, which is included in the delivery set.
