ABSTRACT:
An acetabular cup assembly can include a cup portion and a bearing. The cup portion can include a porous metal outer layer having a first thickness and a solid titanium inner layer having a second thickness. A mating feature can be formed between the cup portion and the bearing. The bearing can be adapted to be selectively secured to the titanium inner layer. In one example, the bearing is formed of cobalt.
