Prosthetic Knee

The Prosthetic knee mechanisms for above knee amputees have had some impressive technological enhancements in technology available in previous decades and continues to do so. These improvements which has helped improve the functionality and safety of the prosthetic knee. Most notably in these improvements is Microprocessor controlled knees (MPK’s). Technological enhancements have integration of hydraulic and pneumatic which is present in most modern-day knees. This allows the knee units to become adaptable to the surrounding area which is imperative when walking on slopes and stairs.

MPK’s are currently implementing designs of a multi-axial knee units which has shown increased stability without the drawback of higher energy expenditure. These improvements made to prosthetic knees allows our prosthetists to create a prosthesis that works to best achieve the most out of your lifestyle and goals that you want to achieve. Along with the enhancements with prosthetic knees, there is now a variety of socket design styles, suspension methods, prosthetic feet, and knee units; your prosthetist will work closely with you to find the most appropriate style based upon your level of amputation, functional capabilities, goals, and activities that you enjoy to the best of your abilities.

Prosthetic Knee FAQs

How many hours can you wear a prosthetic knee?

This is completely dependent on the individual user and their needs, wants and abilities. Lots of people wear their prosthetic knee from when they first wake up in the morning until they are ready to go to bed at night. Other people might only wear theirs for certain activities during the day, such as transferring from bed to wheelchair. Most importantly, a prosthesis should not be worn when sleeping as this can cause unwanted pressure areas to the residual limb.

What is the routine maintenance required for a prosthetic knee?

We recommend that prosthetic users are reviewed at least every 6-12 months for regular maintenance and upkeep of their prosthesis. This time frame may vary depending on individual circumstances, such as change in body weight, body fluid, volume fluctuations, change in activity level, etc. If you are experiencing any issues with your prostheses it is recommended to call our clinic and make an appointment straight away to have your prosthetic knee reviewed and adjusted accordingly.

How are prosthetic knees attached to the body?

The most common way a prosthetic knee is attached to the body is through a prosthetic socket. This is a custom-made socket made from a plaster cast or mould taken of your residual limb. It is modified in a way to ensure comfort and fit when wearing and has attachments for distal prosthetic components. For amputees who have undergone Osseo-Integration surgery, they do not need a socket, as their prosthetic components attach to a metal rod which has been surgically inserted into the bone of their residual limb.
