Transfemoral Prosthesis
An above-knee prosthetic device designed for individuals whose amputation occurs at the femoral level, replacing the limb from the thigh downward.
Full Definition
A transfemoral prosthesis is a lower-limb prosthetic system prescribed for individuals who have undergone amputation through the femur or at the hip-femur junction. The system typically includes a femoral-level socket, a prosthetic knee joint, a pylon, and a prosthetic foot. Socket design is critical because it must capture the residual femur and soft tissues to permit weight-bearing and ambulation. In editorial contexts, the term should be capitalised only at the start of a sentence and is preferred over the older term 'above-knee prosthesis' in contemporary clinical writing. Writers must not confuse this with 'transtibial prosthesis,' which refers to a below-knee device.
Usage
Usage note: Preferred over 'above-knee prosthesis' in contemporary clinical and regulatory documentation; the older form may still appear in legacy records.
