- Socket: Medically called the Acetabular Component. It can be made of highly wear resistant plastic, metal or ceramic.
- Liner: The liner fits snugly into the socket to provide an ultra-smooth surface for the hip joint. It can be also be made of plastic, ceramic or metal.
- Ball: The artificial ball component is smaller than your normal hip ball. It is incredibly polished and perfectly round and smooth. It is usually made of metal or ceramic.
