A new study on patient outcomes after metal-on-metal hip replacement revision surgery has been selected as part of a prestigious 'Game Changers' session at the American Academy of Orthopaedic Surgeons (AAOS) annual meeting.

The biggest study in the world of its kind, researchers specifically investigated outcomes after revision surgery performed for abnormal reactions to metal. The Program Committee for the conference, this year taking place in San Diego, selects work which they feel will change clinical practice within the next two to three years.

Approximately 1.5 million patients worldwide have metal-on-metal hip replacements for painful arthritis. Abnormal reactions to metal can develop which may cause surrounding tissue damage. Many patients with these reactions require further operations, known as revision surgery. Little is currently known about outcomes for patients following these further operations, though initial observations showed patients experienced poor results. This is concerning as most patients who received this type of hip replacement are young and active. Therefore poor results would have a significant impact on a patient's quality of life.
