Patent ID: 8828081

Claim:
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; and at least one fluid deflection structure positioned on 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 deflect synovial fluid away from the bone-prosthesis interface in vivo during physiological movement of the artificial joint prosthesis.
