We will compare the risk of undergoing a second revision between cemented and uncemented revised acetabular component by reporting the absolute risk of second revision of 1) the acetabular component and 2) any other component. The cumulative incidence of revision will be estimated using Fine-Gray regression to model the cumulative incidence function, accounting for the competing risk of death. We will apply both a crude and a multivariable adjusted model adjusting for age, sex, Charlson Comorbidity Index (CCI) and the 5-year intervals during which the primary operation was performed.",[46,47],"Total Hip Arthroplasty (THA)","Revision Hip Arthroplasty",[49,50,51,52,53,54,55],"Cup cementation","total hip arthroplasty","THA","Revision","Second Revision","Re-revision","cement","NOT_YET_RECRUITING","2024-09-04",{"date":59,"type":60},"2024-09-19","ACTUAL",{"date":62,"type":41},"2024-10-01",{"date":64,"type":41},"2026-10-01",{"name":5,"class":6}]
