Ottobock develops pediatric knee joint

Austin, TX-based Ottobock HealthCare in September reported it has developed the first everyday prosthesis with hydraulic swing phase control specifically for children.

The 3R67 prosthetic knee joint is designed to support children aged 6 to 12 years during a variety of activities, including walking and running at different speeds, intuitive kneeling with a flexion angle of up to 150°, and frequent changes of pace while riding a bike or scooter.

The polycentric four-axis geometry of the joint, which weighs 18 oz, ensures stance phase stability and safety, and the prosthesis can be extended as the child grows. Scope of delivery includes a tube clamp adapter, designed to increase in length by up to 2 cm without a new adapter.
