For your convenience, we have created this master page to show you all the main bionic leg components currently on the market, with links to detailed articles on each.
This includes articles on microprocessor ankles, microprocessor knees, and fully integrated bionic legs.
Best of all, we constantly update this list and all its supporting articles, so just bookmarking this page should keep you up-to-date.
Freedom Innovation’s Kinnex is one of the most advanced bionic foot/ankle devices on the market. With a 30-degree range of motion, 3 sensors, and a sophisticated microprocessor, Kinnex automatically adjusts to changing terrain on each step.
Fillauer’s Raize Foot is a lightweight, low-profile bionic foot/ankle. Its microprocessor actively manages flexion resistance for a smoother rollover during the Stance Phase of the gait cycle. It also allows users to adjust heel height to accommodate different shoes.
The Blatchford Elan Foot is another worthy competitor in the bionic foot/ankle market, allowing users to achieve a smooth gait on many different types of terrain. However, it is not waterproof and lacks the type of user software offered by some of its competitors.
The Genium X3 Knee has been compared to a luxury sports car. Sophisticated sensor and microprocessor technologies make navigating challenging terrains routine. Fully waterproof and highly resistant to dust, dirt, corrosion, etc., it is ideal for outdoor activities. It’s only major drawback is cost.
Ossur’s Rheo Knee XC is the premium version of its sister product, the Rheo Knee. Added features include the ability to transition more quickly from walking to running and from walking to bicycling. Users can also ascend stairs step-over-step and navigate obstacles with more stability and safety.
Ossur’s Power Knee is the only bionic knee that augments the user’s residual limb with electric power. This significantly reduces the user’s energy expenditure while also assisting in tasks like standing and ascending stairs. It also helps ensure greater ground clearance during the Swing Phase.
The latest version of Nabtesco’s Allux Knee (Allux 2) was launched in the U.S. in June 2017. Now distributed by Proteor USA, the Allux has some interesting features, especially its use of a 4-bar linkage system. But can it compete with its more established competitors?
The Plie Knee has some unique features that draw both supporters and detractors. While it still sells at an attractive price, its recent acquisition by Proteor USA, scheduled to close by the end of 2020, justifies a wait-and-see approach by prospective purchasers.
Blatchford’s latest version of the Orion Knee (Orion 3) has closed the technology gap with other leading bionic knees in the same price range. The one remaining question is: do prosthetists trust it as much they do its competitors, especially regarding service and support?
