Abstract
A component (1) of a prosthetic joint comprising a portion to secure the component to a bone and a bearing portion having a bearing surface (3) wherein one more reservoir (6) are situated behind the bearing surface (3), one or more magnet assemblies (5) are associated with the or each reservoir (6) and one or more passages (7) are provided extending between a surface of the component and the or each reservoir (6), and wherein either the bearing surface (3) includes magnetic material or a material that in use has a magnetic surface or the component (1) is adapted for use with a further joint component (2) which has a bearing surface (4) that includes magnetic material or a material that in use has a magnetic surface.

A component of a prosthetic joint comprising:
- a portion to secure the component to a bone;
- a bearing portion having a bearing surface wherein at least one reservoir is situated behind the bearing surface
- at least one magnet assembly associated with the reservoir;
- and
- at least one passage extending between a surface of the component and the reservoir, said component being adapted for use with a further joint component which has a bearing surface that includes at least one of a magnetic material and a material that in use has a magnetic surface.
A component of a prosthetic joint comprising:
- a portion to secure the component to a bone;
- a bearing portion having a bearing surface wherein at least one reservoir is situated behind the bearing surface, and wherein the bearing surface includes at least one of a magnetic material and a material that in use has a magnetic surface;
- at least one magnet assembly associated with the reservoir;
- and
- at least one passage extending between a surface of the component and the reservoir.
