Review[Are the concerns regarding metal-on-metal total hip arthroplasties founded in 2012?].
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 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.
