Montalti M, Bordini B, Natali S, et al. - This study was intended to assess and compare survival rates, reasons for re-revisions, mortality rates between these two cohorts. An arthroplasty registry was applied to stratify revision hips according to the reasons for revision (aseptic loosening and PHIs). Researchers recorded pre-operative and intra-operative demographics and implant-related features. They assessed and compared survival rates, reasons for revision, and mortality rates. The results of this study indicate that aseptic and septic revisions achieved similar outcomes at long-terms, re-revisions tended to fail for the same reason for revision. In the septic cohort, the Mortality rate was significantly higher. These data are beneficial to modify and tune the pre-operative, intra-operative, and post-operative management of revisions.
