1. A method of making a prosthetic joint having load-bearing surfaces which interact to enable rotation of one of the load-bearing surfaces relative to the other, the method comprising the steps of:

  • (a) coating at least one of the load-bearing surfaces with a polycrystalline diamond compact; and

    (b) bonding the compact to said diamond-coated load-bearing surface to form a diamond layer over said diamond-coated load-bearing surface;

    wherein step (b) comprises bonding a compact to a first of the load-bearing surfaces by using one of the group of processes consisting of a sintering process under high pressure and high temperature, a high temperature laser, chemical vapor deposition, electroplating and forming a matrix of high molecular weight polyethylene.
