Above Knee Prosthesis (1)

Above Knee Prosthesis

Our Above Knee Prostheses Mimic the Natural Body Using Performance Response Technology (PRT)

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.

Our above knee prosthetics offer:

• 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

Standard Features of an Above Knee Prosthesis

Above Knee Prosthesis

  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. It may then be covered with stockings.

Suspension (not shown) – This holds the artificial limb on to your residual limb. The type of suspension you need will be assessed when you are ready for your measurements to be taken.

Blatchford Ambassadors of Mobility

Our Ambassadors are busy telling their stories and helping others in their community. They are raising public awareness around limb loss and care about making a positive difference in people's lives.

They are inspirational, motivational and unstoppable positive forces in the lower limb amputee community!

Please consider joining our Ambassadors of Mobility! We'd love to have you share your experience as a caregiver in the amputee community!

Understanding Prosthetics

Whether you are a new amputee or have lived with amputation for awhile, prosthetic technology can be overwhelming. We explain some of the technology behind today’s prosthetics and how Blatchford uses the natural working of the human body to influence the design of our products.
