Ottobock Mechanical Knees

Ottobock offers a comprehensive range of mechanical prosthetic knees designed to support individuals across a wide spectrum of mobility levels. From locking knee joints for users with very limited mobility to highly advanced solutions for more active individuals, our portfolio is built to deliver dependable stability and reliable performance.

Several of our knees incorporate specialized mechanical designs to support improved stance control and gait dynamics. For example, the patented 5-axis design of the 3R60 enables controlled stance flexion to promote a smoother gait cycle, while the robust, waterproof 3R80 is designed for users who require a durable knee for more demanding environments and activities.
