The aim of this systematic review is to answer three questions.
Ceramic on ceramic hip replacement bearings.
In 1995 an improved alumina ceramic was developed that had increased purity and strength over the first generation materials.
The type of ceramic used in total hip replacement today is aluminum oxide also known as alumina.
Modern manufacturing techniques and developments have increased the strength and reliability of ceramic materials.
At present ceramics are used only in the hip because hip components have simple design and shape.
There is minimal dimensional mismatch between the head and cup and there is no translational movement.
Ceramic on ceramic hip prostheses are an increasingly popular choice for hip replacement.
The alternative bearing couples such as metal on polyethylene and metal on metal are more inclined to wear and produce particulate debris.

1 are there risk factors for ceramic component fracture following total hip replacement.
Ceramic bearing surfaces are increasingly used for total hip replacement notwithstanding that concern is still related to ceramic brittleness and its possible mechanical failure.
