ABSTRACT:
A prosthesis for an artificial joint is provided with an interior passage which communicates with the joint area so that fluid from the joint circulates through the passage. Wear particles carried by fluid are deposited by gravity within the passage. Alternatively, a particle collecting filter is positioned in the passage, or in the case of a prosthesis formed from a magnetizable metal, a portion of the passage wall is magnetized to collect metal wear particles.
