Artificial joint components including synovial fluid deflecting structures and particle retaining structures

Patent Number: 9387081

Patent Date: 2016-07-12

Patent type: utility

Artificial joint prostheses, including hip, knee and shoulder joints, are described. In some aspects, an artificial joint prosthesis includes: a bone-facing surface of an 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, the non-contact surface adjacent to the bone-facing surface of the artificial joint prosthesis; at least one fluid deflection structure attached to the non-contact surface, the fluid deflection structure positioned to direct a flow of synovial fluid away from the bone-prosthesis interface in vivo; and at least one particle retaining structure positioned to contact the directed flow of synovial fluid and configured to retain particles present within the synovial fluid.
