Those who walk very slow, but always follow the
right path, can get much further than those who
run and get carried away.

The development of the Kenevo
•The goal when creating the 3C60 was to
create a knee joint with special
functionalities to address the unique
needs of the low mobility population
•Some functions are based on well
established principles (e.g. default stance)
•Most functions are the result of specially
developed technologies and algorithms
(e.g. Stumble recovery plus, activity
modes, wheelchair function, intuitive
bicycle ergometer function)
