Conclusion Based on the current data , the use of DM acetabular components are effective in minimising the risk of instability after both primary and revision THA .
This benefit must be balanced against continuing concerns about the additional modularity , and the new mode of failure of intraprosthetic dislocation .
Aims The aim of this systematic review was to report the rate of dislocation following the use of dual mobility ( DM ) acetabular components in primary and revision total hip arthroplasty ( THA ) .
Acetabular reconstruction using a Kerboull cross-plate, structural allograft and cemented dual-mobility cup in revision THA at a minimum 5-year follow-up.
The current study aim ed to evaluate the outcome of a continuous and prospect i ve series of 61 revision THAs with AAOS grade III and IV acetabular bone defect reconstruction using a Kerboull cross-plate , structural allograft and cemented dual mobility cup ( Saturne , Amplitude , Valence , France ) . At a 7.5-year mean follow-up , no instability was reported after revision . In addition , no failure of the acetabular reconstruction was observed in 98 % of the patients with complete allograft osseointegration and no evidence of mechanical rupture of the Kerboull cross-plate and /or loosening of the cemented dual mobility cup . In conclusion , such reconstruction technique demonstrated excellent results at mid-term follow-up in terms of prevention of instability after revision , restoration of the acetabular bone stock , and stable cemented fixation of the dual mobility cup
