A transfemoral prosthesis is an artificial limb that replaces a leg missing above the knee. Transfemoral amputees can have a very difficult time regaining normal movement. In general, a transfemoral amputee must use approximately 80% more energy to walk than a person with two whole legs.This is due to the complexities in movement associated with the knee. In newer and more improved designs, hydraulics, carbon fiber, mechanical linkages, motors, computer microprocessors, and innovative combinations of these technologies are employed to give more control to the user. In the prosthetics industry a trans-femoral prosthetic leg is often referred to as an "AK" or above the knee prosthesis.
The below-knee prosthesis of has been designed indigenous. The shank is fabricated from CFU manufacturing unit, durable, high-quality, high-density polyethylene pipes . The socket design used is either total contact, which is vacuum-formed using a polypropylene sheet, or open-ended, using HDPE sheet. This custom-made shank / socket is fitted with the artificial Foot.
