This is the component that is custom made for each individual and the part your residual limb fits into. Various designs available and your prosthetist will discuss these with you to tailor the most appropriate socket for you.
The interface is the part of the prosthesis that goes next to your skin; this may be made of various gels like silicone, foam or even something as simple as a prosthetic sock.
This is the mechanism used to hold the prosthesis onto your limb. It may incorporate a gel liner with a locking pin, a suspension sleeve or it can be held on by suction. These various types should be discussed with your prosthetist during the design stage to help make the prosthesis better accommodate your lifestyle and limb type.

- Microprocessor Controlled (MPC) knees:
The introduction of the 3C100 C-Leg® microprocessor-controlled knee-shin system in 1999 from Otto Bock initiated a revolution of sorts in trans-femoral ambulation. Essentially, the C-Leg’s on-board circuitry does the thinking and lets the above-knee amputee concentrate on other things while walking. The C-Leg functions through real-time gait analysis to control hydraulic swing- and stance phase resistance. Built-in sensors provide information to the microprocessor 50 times per second to determine the precise phase of gait. The microprocessor then makes instantaneous adjustments to knee function, using algorithms developed from studies of how thousands of people walk, fine-tuned for the wearer’s unique needs and characteristics.
The SYMBIONIC LEG from Össur is the first complete bionic leg. Combining a powered ankle and an adaptive microprocessor knee joint, the SYMBIONIC LEG provides unmatched benefits for trans-femoral amputees. The active toe lift in swing clears the ground and minimizes the risk of tripping. Should a stumble occur, an advanced stumble recovery feature protects the user from a fall by providing instant stance support.
New developments in Össur's proven bionic technology mean that the RHEO KNEE can recognize and respond even better to the most subtle changes in walking speed and terrain. Using sophisticated artificial intelligence, it continuously learns and adapts to an amputee's walking style and environment.
The POWER KNEE remains the world‘s first and only motor-powered, artificially intelligent prosthesis for above-knee amputees and defines the future of lower extremity prosthetics. This knee works as an integrated extension of the user, designed to restore the power of lost muscles and symmetry of movement that is vital for those with limb loss. The POWER KNEE gives users the ability to cover greater distances than they could previously. Confidently negotiating obstacles and inclines has never been easier, and ascending stairs foot-over-foot is now possible.
The GENIUM’s many sensory inputs allow you to walk up stairs step over step, under your own power. Supported by a stable, flexed knee when your foot hits the ground, you can cross every day obstacles more smoothly, without awkwardly swinging your prosthetic leg around the impediments of daily life.
The Genium allows you to walk backward and forward with ease. The knee detects forward and backward motion and provides support as needed which helps make standing easier. The Genium can tell when the user is standing and automatically resists further flexing. This translates into a relaxed state while standing, saving energy and taking stress away from the sound side. You can even stand relaxed on inclines and uneven surfaces which can be tricky. Switching between the 5 available activity modes is easy and convenient. The hand-held remote control also includes a battery level monitor and step counter.

- Microprocessor Controlled (MPC) Feet:
Up to now most of the advances in prosthetic feet have been liked to design and particularly the use of lightweight composite materials; particularly, carbon fiber. Incorporating an “active” ankle has been accomplished with the use of a hydraulic ankle joint. The intent is to more closely mimic the human ankle while on uneven terrain. With the technological advances in batteries, microprocessors, and motors changes are being made rapidly in the prosthetic foot industry.
Listed below are three popular MPC feet that we have had much success with here at Rebound. These all very different in concept, design and function so we value the fact that the manufacturers allow us to let you trial the feet. These are very expensive devices and trialing the foot allows you decide which is best for you.
The BiOM Ankle System provides Bionic Propulsion, a breakthrough technology that will help you achieve your goals and improve your mobility. This unique ankle technology actually powers movement and produces a more natural gait. Since all other commercially available ankle devices do not provide natural Bionic Propulsion during the walking stance phase (when the foot is in contact with the ground) significant gait deviations occur. For the first time in prosthetic history Bionic Propulsion energizes a person’s gait, providing programmable ankle stiffness modulation and power assist. By replacing lost muscle function, Bionic Propulsion improves your mobility – to have the stamina to walk greater distances…faster. It’s designed to make you feel safer and more stable on stairs, ramps and uneven terrain - to do the things you want to do…without thinking about your mobility.
The BiOM Ankle System is bionic; unlike any other commercially available ankle device. The BiOM replaces the function of your lost muscle and tendon anatomy, stiffening and powering your prosthetic ankle in a manner directly comparable to what muscles normally do in the biological leg. You can now walk with a more natural gait than you would with any other prosthesis, allowing you to live more independently, return to work, and live life with greater enjoyment and ease.
PROPRIO FOOT offers an unprecedented level of mobility and stability for a world that is not flat. The powered ankle motion, intelligent terrain adaptation, and natural function of the foot make it the most life-like prosthetic foot available, giving its users the power to overcome all of life’s obstacles.
PROPRIO foot lifts the toe to reduce the risk of trips and falls.
It also mimics natural ankle motion to facilitate chair exit, reducing strain on the knees, hips, and back. It also adjusts to different heel heights, allowing the user to safely change shoes while maintaining symmetry and alignment. The foot and ankle relax to flatten discretely to the ground when in a seated position, reducing pressure in the socket and knee while improving symmetry.
The Endolite élan foot is a revolutionary new prosthetic foot/ankle system with microprocessor controlled speed and terrain response. Sensors continuously monitor environmental feedback and the algorithm changes the foot characteristic to offer the safest, most comfortable and energy efficient response on the flat, descending or ascending ramps and stairs. The hydraulic ankle control ensures silent operation and sinuous movement that biomimetically matches the Activity Level 3 user’s body and walking style.
