What Is the Long-term Survival for Primary THA With Small-head Metal-on-metal Bearings?

CONCLUSIONS: Despite survival that is substantially greater than that of large-head MoM THAs, there has been a marked decrease in the use of small-head MoM designs in our registry. Although the reasons for this are likely multifactorial, the increasing incidence of revisions for ARMD among small-head MoM THAs is concerning.
LEVEL OF EVIDENCE: Level III, therapeutic study.
