Research Facts
This hip prosthesis was designed by Sir John Charnley; it was the first of its kind of hip joint, with a (22 mm) smaller head designed for less wear on the socket; this type of prosthesis was originally used with Teflon sockets, 2/3 of which wore out within six months; these were replaced with high-density polyethylene sockets.
