Abstract
An acetabular shell component includes a solid substrate, a porous outer layer coupled to the solid substrate, a porous inner layer coupled to the solid substrate, and an inner bearing coupled to the porous inner layer. One or more adjuncts extend outward from the porous outer layer. Each adjunct includes an outer surface that defines a customized patient-specific negative contour shaped to conform to a positive contour of a patient's bone. A method for manufacturing the acetabular shell component using an additive manufacturing process is also disclosed.
