摘要：
Prosthetic artificial joints are described, including hip, knee and shoulder joints. In some embodiments, an artificial joint prosthesis includes: a bone-facing surface of a artificial joint prosthesis, the bone-facing surface configured to face a bone-prosthesis interface in vivo a first component of the artificial joint prosthesis including a contact surface of the artificial joint prosthesis, the first component fabricated from at least one polymer and a plurality of magnetic particles and a second component of the artificial joint prosthesis including at least one magnet configured to create a magnetic field within the artificial joint, the at least one magnet positioned to form a magnetic field directed to influence a location of debris including the magnetic particles in the joint to a position distinct from the bone-prosthesis interface in vivo.
