Abstract
One embodiment of the implant comprises a porous metal bone ingrowth portion () having a first side connected to a high density or solid (fully dense) metal portion () which in turn has an opposite side connected to a porous metal soft tissue ingrowth portion () thus forming a sandwich structure with the high density or fully dense portion in the middle. The implant may be made of a resorbable material such as an alloy of magnesium. Alternately, the alloy can be selected from the group consisting of calcium, iron, yttrium and lithium. The porous metal soft tissue ingrowth portion () has porosity characteristics allowing cartilage to interdigitate with the pores and extend outwardly beyond the platform of the metal surface towards a joint capsule. The solid or fully dense intermediate layermay have some porosity, however that porosity prevents either bone tissue or cartilage tissue from migrating therethrough.
