What are basic components of a prosthesis that a below-knee amputee would use?
Individuals with below the knee deficiencies may benefit from a suspension device known as a supracondylar cuff. This device is sometimes referred to as a Patellar Tendon Bearing Supracondylar Cuff since most of the weight bearing of the residual limb occurs through the patellar tendon as well as through the inner knee. The patellar tendon is a soft tissue structure that runs from the knee cap or patella and inserts onto the upper shin and is able to withstand a significant amount of weight. This prosthesis is held onto the lower limb via cuffs that extend above the knee. There are two bony prominences above the knee joint called condyles which project out. The cuff of this socket hangs onto these condyles keeping the prosthesis suspended onto the lower limb, hence its name. Occasionally, added suspension is provided by using a Silesian or TES belt as described above. Some amputees may also use a liner over their residual limb to help improve the contact between the limb and the prosth
