82 <strong>Dansk</strong> <strong>Hoftealloplastik</strong> <strong>Register</strong> – <strong>Årsrapport</strong> <strong>2009</strong> Overlevelseskurver efter revisioner Alle revisioner Analyserne viser, at 2. gangs revision med endepunkt 3. revision har signifikant dårligere overlevelse end 1. gangs revision med endepunkt 2. revision. Revisionsårsag Prognose for 1. gangs revision på grund af aseptisk løsning er signifikant bedre end efter dyb infektion og luksation. Prognosen efter dyb infektion er dårligere end efter luksation. Revision og knogletab Der synes ikke på nuværende tidspunkt at være sammenhæng imellem knogletab ved revision og proteseoverlevelse på acetabulum siden. Det kan skyldes, at de væsentligste årsager til tidlig revision, som infektion og luksation, er uafhængig af knogletabet. Derimod er der på femur-siden en tendens mod flere re-revisioner i gruppen med større knogletab (type 3 og4) sammenlignet med type 1 og 2. Det skal bemærkes, at opfølgningen endnu er kort og at tallene i nogle af grupperne er små.
