What is a total knee replacement?

When the cartilage has worn away, an artificial knee (called a prosthesis) can take its place. The surgery to implant the prosthesis is termed a total knee replacement. Only the surface of the joint is removed - the arthritic ends of the bones are shaved off and replaced with new metal and plastic surfaces. The knee replacement recreates the normal function of the knee. While the idea of getting an artificial knee joint may be frightening to some, it is one of the safest and most effective medical procedures.
