Uncemented double-mobility acetabular cups, first used in the late 1970s as a solution to recurrent hip dislocations, have proved efficient in reducing dislocation rates while preserving an important range of motion. The low wear-rate and low mechanical stress on the bone to cup interface enhances survival.

New instrumentation has permitted design changes that improve the dislocation coverage of the cup (upper part of the cup) and reduce the risk of impingement with the femoral stem (lower part of the cup).

Indications for the use of double-mobility cups have increased. They include primary total hip arthroplasty in relatively unstable hips, in which cases we use the Avantage® press-fit or 3P cup with an AURA II anatomical uncemented or cemented stem, dysplasia (in congenital high dislocations we use the press-fit or 3P or revision cup with an AURA revision stem, and in dysplasia we use small AURA II or Vectra or CMK dysplastic stems), muscular deficiency, in which Avantage® cups can be used with AURA II or revision stems, resection prosthesis or ARMEL calcar prosthesis, etc.)
