AK2 prosthesis are made with suction socket and polycentric knee. The suction socket is used to provide greater ease of use to polycentric, making activities for people with disability smooth and effortless. The polycentric knee is designed to work as a natural body part, and therefore, it is more firm and durable. It also aids greater balance because of its strength and movement easiness. Its graphic look is consistent, and it provides balance up to 15 degrees. Polycentric knee reduces the size of calves, protecting the user from fall and imbalances. To increase the movement of our patients, our team introduced pneumatic joints as per patient’s requirements. Pneumatic knee joints bring faster and circular movement and are considered to be in the higher range of joints worldwide.
