Ottobock launches first prosthetic knee for children that ‘grows with the user’

Ottobock’s 3R67 prosthetic knee joint

German prosthetics manufacturer, Ottobock, has developed what it claims to be the first everyday prosthesis with hydraulic swing-phase control specifically designed for young amputees.

The prosthesis grows along with the child thanks to a tube clamp adapter where the length can be adjusted by up to two centimetres.

The 3R67 prosthetic knew joint is designed to meet the everyday demands of children aged six to twelve years including playtime activities that involve different walking and running speeds, intuitive kneeling with a flexion angle of up to 150°, and frequent changes of pace whilst riding a bike or scooter.

The polycentric four-axis geometry of the joint ensures a high level of stance phase stability and safety. The 3R67 claims to provide young amputees with reliable support at any walking speed and enables spontaneous actions.

The durable, robust design, is designed to allow the 3R67 to withstand the widely varied demands of sports and playtime activities. With a net weight of 510g, the joint offers good freedom of movement.
