Abstract:
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; at least one fluid deflection structure attached to the non-load bearing surface, the at least one fluid deflection structure including at least one flange structure positioned to extend from the non-load bearing surface, the at least one flange structure including a first end connected to the non-load bearing surface and a second end distal to the non-load bearing surface, wherein the at least one flange structure is widest at the first end and narrowest at the second end, 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.
