The USMC A5 has a dual regulated Pneumatic system that can change the walking speed according to the user's walking habits. The swing and bending of the knee joint are closer to the function of the human knee joint, making the user's gait look more natural. Its multi axis design enhances stability, with a load-bearing capacity of up to 125kg and a flexion angle of approximately 160 °. Therefore, the USMC A5 is suitable for users with moderate activity. Users wearing the USMC A5 knee joint will feel more stable and safe when transferring their center of gravity, and more confident when walking.

Product characteristics:
1. The stretching/flexion dual adjustment Pneumatic system can change the walking speed according to the user's walking habits, resulting in natural and smooth walking.
2. The swing and bending of the knee joint are closer to the function of the human knee joint, making the gait more natural.

3. The knee joint adopts a unique humanoid knee joint locking function, allowing users to ensure safety during walking, just like the human knee joint during heel landing and support periods. When the sole of the foot is off the ground, the knee joint can simulate the physiological function of the human knee joint to easily and naturally bend and walk.

4. The design of the multi axis knee joint ensures a balanced distribution of the bearing capacity of the rotation axis during the walking support period, greatly extending the service life of the knee joint.
5. Equipped with a fully sealed needle roller bearing design, it is different from other knee joint ball bearings or sleeve type designs currently on the market.
6. The large angle design for knee flexion provides convenience for users, with a flexion angle of approximately 160 degrees.
7. Suitable for users under 125 kilograms.

The design of the USMC A5 knee joint conforms to human anatomy and is more compact and lightweight. Its stable design allows users to safely walk on uneven surfaces, allowing them to freely match various foot boards, attend various occasions, and have an unlimited good life.

The assembly of all components of the knee is done through the fitting of screws or nuts, so the user only needs to assemble the matching components and then lock and fix the screws or nuts. Users can adjust the screws that momentarily rotate the knee joint according to their own mobility to increase or decrease the sensitivity of the joint. They can also adjust the regulating valve on the knee joint pressure body to increase or decrease the speed of joint bending or extension.
