Ottobock Microprocessor Knees: Trust, Move, Live.

Ottobock launched the first fully microprocessor-controlled knee in 1997 and remains the world’s leading manufacturer of MPKs to this day. Over the last 25 years, we have continually updated our systems based on both scientific research and feedback from users about what they really need.

For example, your prosthetist will program your microprocessor knee to match your walking pattern. Many systems won’t vary from this programmed pattern until they’re checked again. But Ottobock MPKs continually monitor the phases of your gait, adjusting in real time to support you as you speed up or slow down.

All prosthetic knees are designed to emulate two phases of your natural walking pattern or “gait cycle”:

During stance phase, your foot is on the ground. Your leg is slightly bent, acting as a shock absorber while providing enough resistance to support your weight.

During swing phase, your foot is in the air and swinging forward. Your knee flexes more so that your foot can clear the floor as it swings forward into the next step.

But it’s the way they recreate these phases of gait that separates one type of prosthetic knee from another.

Mechanical knees are usually controlled by a mechanical lock, friction, or pneumatic or hydraulic fluids. Often only body weight is used to activate the stance control mechanism, leading to a less natural walking pattern.

Microprocessor knees use sensors, software, and a built-in computer to adjust fluid-based resistance to your unique gait. This makes it easier to walk at varying speeds and safely descend ramps and stairs.

The bottom line? MPKs empower you to walk with a more stable, natural, and efficient gait.

Description: Those with Level 1 mobility typically use their prosthesis only for transfers or moving slowly on level floors. Walking time and distance are likely very limited due to overall physical condition.

Therapy Goal: Restore the ability to stand and walk indoors for short periods.

Ottobock MPK Options: Kenevo

Description: Users can typically walk slowly with their prosthesis and negotiate low obstacles, such as curbs, single steps, and uneven surfaces. Walking time and distance are still limited.

Therapy Goal: Restore the ability to stand and walk both indoors and outdoors.

Ottobock MPK Options: Kenevo, C-Leg, Genium X4

Description: Users can walk with their prosthesis at medium-to-high speeds, vary their speed, and overcome most natural obstacles. They can typically engage in professional, therapeutic, and other activities that don’t put too much strain on their prosthesis. And while there may be an increased need for safety (perhaps due to additional disability or special living conditions) combined with medium-to-high mobility demands, walking time and distance are only slightly restricted.

Therapy Goal: Restore the ability to stand and walk, both indoors and outdoors, with only mild restrictions.

Ottobock MPK Options: C-Leg, Genium X4

Description: Users are generally able to walk outdoors with little or no restriction, for any amount of time or distance. Due to high functional demands, significant shock, tension, and distortion can occur.

Therapy Goal: Restore the ability to stand, walk, and move both indoors and outdoors without any limitations.
