Why Choose a Microprocessor Knee?

What’s the difference between a microprocessor knee and a mechanical knee prosthesis? How do MPKs work exactly? And what sets Ottobock solutions apart? Here’s a quick overview to answer your most pressing MPK questions.

Stance, Swing, and Everything in Between

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.

Answers to common MPK questions

Activity Levels

Your activity level (or “mobility grade”) is a number between 1 and 4 that indicates your overall physical condition and potential for benefiting from various prosthesis options. Your prosthetist will assess your activity level and use it to set therapy goals and determine which solution is most likely to maximize your mobility and quality of life.

Activity Level 1

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.
