Above-knee fitness prosthesis
The only fitness prosthesis designed for above-knee amputees
Along a beach, over a trail, on the track . . . there’s nothing like the satisfaction of a good workout.
Ottobock’s Fitness Prosthesis makes it possible to get up and moving again.

Two choices of soles add even more versatility and performance to the prosthesis. The all-terrain tread provides just the right amount of grip for a variety of running surfaces while the spiked tread is designed specifically for use on a track.
To ensure a comfortable fit, your socket will be created to uniquely fit your limb. Especially during running, the fit of the socket is vitally important. To prevent problems, you should work with your prosthetist to make sure your socket fits perfectly. Liners can add another layer of comfort for your limb. We even have liners that fend off bacteria and odor as well – great for workouts! Learn more about sockets, liners, and sleeves at Prosthetics 101.
You’ll get an easy, powerful “lift-off” from a secure foot strike every time, thanks to a lightweight, durable carbon spring. This foot is available in six different stiffness levels to provide the precise blend of dynamic performance for your personal running style.
Performance to match your workout level
Built to accommodate rapid changes in running speeds, the Fitness Knee will keep up no matter the intensity of your workout routine. Durable and responsive, the knee’s compact, lightweight design is a bonus for amputee runners at all fitness levels – from weekend jogs to competitive sprints. You’ll also appreciate the manual lock for security during warm-ups, stretching or other activities.
