1. A prosthetic device with a reinforced composite precoat, comprising:

  • a. a prosthetic device adapted to have at least a portion implanted in a cavity formed in animal bone;

    b. a relatively thin layer of cured bone cement precoated on the outer surface of the prosthetic device before implantation on at least part of the portion adapted to be implanted in the bone cavity; and

    c. a reinforcing fibrous mat formed of high strength polyolefin fibers encapsulated within the cured bone cement precoating so that the fibers define a reinforcement to the cured bone cement layer prior to implantation, the fibers being oriented in at least one direction and interconnected to form a flexible network; and

    d. the precoating outer layer defining a cured bone cement surface covering the fibers to provide a generally smooth outer layer so that the cured bone cement surface can be used to cary wet cement for forming a bond between the precoat and the animal bone.
