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; and
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 connection to other portions of the artificial joint prosthesis and to the bone-prosthesis interface, 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.

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.
