A transfemoral amputation, also known as an above knee amputation, is an amputation at or above the knee joint. An above knee prosthesis is used to replace this part of the missing leg.
If you want to learn more, please visit our website above knee prosthetic leg covers.
An above knee prosthesis is comprised of a suspension sleeve, socket, prosthetic knee, pylon and prosthetic foot, with the prosthetic socket being the most important part your prosthesis. Different factors are used to determine what type of prosthetic componentry will be best for your individual functional level.
The certified prosthetists at Prosthetic Orthotic Solutions International, specialize in lower limb prosthetics and work closely with prosthetic leg manufacturers so we can offer our patients the latest in prosthetic foot and knee technology.
Working as a team, we will make a prosthetic device for you based off information we gather during the evaluation phase. The first step in the prosthetic leg fitting process is to take an impression of your residual limb. At POSI, this impression is captured by hand casting as this method provides a very intimate fit that will maximize comfort and support.
At POSI, we understand the unique challenges you will face after an above knee amputation. We work with you and your caregivers through those challenges, we share resources, we coordinate peer support and we work with your rehabilitation team to ensure progress is being made.
Our goal is to provide innovative prosthetics based on biomimetic design principles that work perfectly in sync with the body to provide efficiency of movement and function. We call this type of design Performance Response Technology®, the next generation of biomimetic prosthetics. Biomimicry is a practice that learns from and mimics the strategies found in nature to solve human design challenges.
We actively engage in the science of gait and focus our efforts on designing products that are based on a sound understanding of these principles.

An above-knee prosthesis is also called a transfemoral prosthesis.
Our above knee prosthetic devices include a variety of offerings:
&#; A fully integrated, microprocessor controlled lower limb system for above knee amputees
&#; Microprocessor controlled devices (pneumatic)
&#; Robust hydraulic knees for active users
&#; Locking and free option knees with weight activated stance control for moderately active users
&#; Waterproof prosthesis designed for use in the shower or wet environments
Socket &#; Most modern sockets are either laminated or thermoplastic and some have a flexible thermoplastic inner socket inside the more rigid outer, weight bearing structure. Occasionally a prosthetist will create one made of metal or wood.
Knee Joint &#; There are various types of knee joints. Some are designed to swing; others are designed to stay in a locked position for walking but can be unlocked for sitting.
Note: Prosthetic knee-joints are only
used when your amputation is at a
level through the natural knee-joint or
higher up the leg.
Shin Tube &#; This lies between the prosthetic knee joint and the prosthetic foot. It is made of strong lightweight material such as carbon fibre, aluminum or titanium.
Prosthetic Foot & Ankle &#; There are many different types of feet and ankles available. Your individual needs will influence the choice made.
Cosmesis/Cover (not shown) &#; This a cosmetic cover that gives shape and appearance to the limb. Most artificial limbs are covered with a continuous foam tube that is shaped to match your remaining limb as closely as possible.
