plasty. Dual-mobility bearings may lower the risk of dislocation. The authors report the results of a multicenter study evaluating the use of a dual-mobility acetabular cup design that was cemented into a metal shell as part of complex acetabular reconstructions or in cases where the risk of dislocation was felt to be high, such as isolated bearing exchanges. Eighteen patients were identified for being at high risk of dislocation who underwent cementation of a dual-mobility shell that is specifically made for cementation, into a fully porous metal revision acetabular cup (10 patients) or into a well-fixed cup at the time of revision without removal of the existing acetabular component (eight patients). Patients were assessed
