Revision of cemented acetabular components is most commonly performed because of aseptic loosening with migration of the component. The most challenging aspect of acetabular revision is the management of bone loss compromising implant fixation and stability. The severity of bone loss can be pronounced, as a result of asymptomatic osteolysis and stress-shielding, prior to migration of cementless components. This bone loss is a common condition that is expected to become more common in the future.
