In 1997, the C-Leg® was introduced to the world as a powerful alternative choice to mechanical knees. With more than 100,000 fittings and more than 25 years of practical experience and research, Ottobock has created a family of unmatched microprocessor knees developed to meet the specific needs of people with different lifestyles.

With the family of Ottobock knees, you are able to make informed clinical decisions and deliver a knee chosen specifically for the individual’s level of function, ability, and activities.

*Daily charging recommended
**Service may occur sooner if the knee reaches specific condition-based thresholds.
***More specifically, for patients who walk with speeds of up to 1.9 mph and up to ½ mile outside the house per day.
