1. An artificial joint prosthesis, comprising:

  • a bone-facing surface of an artificial joint prosthesis, the bone-facing surface configured to face a bone-prosthesis interface in vivo;

    a non-load bearing surface of the artificial joint prosthesis, the non-load bearing surface adjacent to the bone-facing surface of the artificial joint prosthesis;

    an aperture in the non-contact surface of the artificial joint prosthesis;

    a substantially round cavity in the artificial joint prosthesis adjacent to the aperture;

    a mechanism including a substantially round element of a size and shape to correspond to the substantially round cavity, the substantially round element positioned to move within the substantially round cavity;

    at least one fluid deflection structure attached to the substantially round element and projecting through the aperture; and

    at least one particle retaining structure positioned to contact the directed flow of synovial fluid and configured to retain non-physiological particles present within the synovial fluid.
