Revision Arthroplasty for Bilateral McKee-Farrar Hip Prostheses 48 Years Following Implantation.

The McKee-Farrar hip prosthesis gained popularity in the 1960s and was one of the first widely used prostheses to employ a metal-on-metal design. Eventually, it laid the framework for the development of second and third-generation hip replacement prostheses. In time, the McKee-Farrar prosthesis was found to have high rates of early aseptic loosening and fell out of favor, especially with the development of the Charnley low-friction metal-on-polyethylene design.
