Prostheses, Lower Limb, Knee Disarticulation
Definition : Lower limb prostheses designed for partial functional (e.g., rotation, flexion) replacement of a missing limb amputated at the knee articulation, in which the femoral component of the articulation is preserved. These prostheses typically consist of external or partially implantable devices, including foot and ankle components at the distal end and a dedicated knee component at the proximal end. A two-section mechanism with an anchor in the upper section connects to the socket, and frequently, linkage bars connect the upper and lower sections. Some prostheses include hydraulic or pneumatic devices and/or microprocessors to regulate the knee movements. Disarticulation knee prostheses are attached at the proximal end to the residual limb (i.e., the intact femur) with a socket; they are available in a great variety of configurations and sizes. Lower limb disarticulation knee prostheses are used mainly in patients who have congenital abnormalities or who suffered amputations due to illness (e.g., diabetes) or traumatic accidents.
