Hip replacement metal on crosslinked polyethylene (MOXP), ceramic on ceramic (COC), ceramic on crosslinked polyethylene (COXP) and metal on metal (MOM).

The direction of the acetabular cup influences the range of motion of the leg, and also affects the risk of dislocation.

Risks and complications in hip replacement are similar to those associated with all joint replacements. They
