Mortality and Implant Survival With Simultaneous and Staged Bilateral Total Hip Arthroplasty: Experience From the Australian Orthopedic Association National Joint Replacement Registry

Abstract

Background Total hip arthroplasty (THA) is an effective procedure for relieving pain and restoring function in osteoarthritis. A significant proportion of patients have severe disease bilaterally. Consensus regarding safety and selection of patients for simultaneous bilateral THA or the optimal timing for staged THA has not been reached. The aim of this study is to compare rates, causes of revision, and 30-day mortality between simultaneous and staged bilateral THA using data from the Australian Orthopedic National Joint Replacement Registry. Methods Data for 12,359 bilateral THA procedures were collected from September, 1999 to December, 2017. Rates and causes of revision and 30-day mortal..
