Title: Artificial joint components including synovial fluid deflecting structures

Abstract: Artificial joint prosthetic components including synovial fluid deflection structures are described. Embodiments of artificial joint prosthesis include those with: a bone-facing surface of a artificial joint prosthesis, the bone-facing surface configured to face a bone-prosthesis interface in vivo; a non-contact surface of the artificial joint prosthesis; and at least one fluid deflection structure positioned on the non-contact surface, the fluid deflection structure positioned to deflect synovial fluid away from the bone-prosthesis interface in vivo.
