Claim Text:
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 substantially rigid 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; at least one substantially flexible fluid deflection structure including a first end attached to the non-load bearing surface and a second end distal to the non-load bearing surface, the second end structured as free of contact with other portions of the artificial joint prosthesis and with the bone-prosthesis interface, the fluid deflection structure positioned to direct a flow of synovial fluid away from the bone-prosthesis interface in vivo during physiological movement of the artificial joint prosthesis; 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.
