However, this technology introduces additional interfaces that have the potential to result in unforeseen complications. We present a series of 3 patients with mechanically assisted crevice corrosion at the acetabular component–metal dual-mobility liner interface. Consequently, we urge judicious use and close clinical observation of this new, effective technology in THA.en-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalDual mobilityTotal hip arthroplastyAdverse local tissue reactionTrunnionosisCorrosionRevisionArticle
