The development of new artificial hip joint systems is mainly influenced by the decreasing age of the patients. Therefore non-cemented artificial joint components are favoured due to a better biocompatibility and a reduced bone resection in comparison to cemented components. State of the art regarding cementless hip joints are metal cups with a porous structure at the back side to induce bony ingrowth.
A possible improvement for the patient is to reduce the bone resection required to a minimum. This is done by developing an implantable full ceramic cup. To provide the ingrowth of bone at the rear of the shell, a osseointegrative coating is essential.
