Ottobock is a German prosthetics company situated in Duderstadt with 49 local stations all around the world. It has been responsible for several innovations in prosthetics, including the C-Leg, a computerized knee joint that adaptively varies its passive resistance to suit the patient's different walking gaits, and the Michelangelo Hand, a fully articulated robotic hand prosthesis. In 2017, the company bought Bebionic, the high technology robotic hand, from the Steeper, US company that developed prosthesis, and has become the most high-tech company in upper extremities. Ottobock has been a partner to the Paralympic Games since 1988, and an international worldwide partner to the International Paralympic Committee since 2005. In 2016, the partnership was extended until the end of 2020.
