Abstract

Metal-on-metal total hip arthroplasty (MOM THA) fuels debate in the orthopedic community after statistics showed higher-than-expected short-term failures in comparison with metal-on-polyethylene THA. The problem of early failure in the young, active patient with a metal-on-polyethylene implant has prompted the research of another couple. Multiple studies showed the advantages of MOM THA. The results of MOM resurfacing and MOM THA in our hospital did not show concerning results. Nonetheless, the data in the literature shows divergent opinions. The most recent statistics indicate that the results are disappointing, particularly with specific types of implants. Several institutions, in the USA and in Europe, are developing protocols for the follow-up of patients with MOM hip implants. Today, we are headed towards imposing a moratorium on using MOM THA.
