A total of 92 cup revisions using the cranial socket system were clinically and radiologically analyzed with an average follow-up of 4.2 years. Defects were classified according to D'Antonio. There were 39 type II, 38 type III, and 15 type IV defects. The Harris Hip Score increased from 41.1 preoperatively to 62.3 points postoperatively. Six patients had recurrent hip dislocation requiring replacement of the inlay. In five cases of aseptic loosening, the acetabular component had to be revised. With revision of the acetabular component as an endpoint, implant survival was 94,6% after an average of 4.2 years.
