Revision risk by using the direct superior approach (DSA) for total hip arthroplasty compared with postero-lateral approach:early nationwide results from the Dutch Arthroplasty Register (LROI)

Background and purpose — The direct superior approach (DSA) is a modification of the classic posterolateral approach (PLA) for total hip arthroplasty (THA), in which the iliotib-ial band and short external rotators are spared. The revision rate of the DSA has not been investigated previously using arthroplasty registry data. We examined the reasons and risk of revision of the DSA, compared with the direct anterior approach (DAA) and PLA. Patients and methods — In this population-based cohort study we included 175,543 primary THAs performed between 2014 and 2020 (PLA, n = 117,576; DAA, n = 56,6... Mehr ...
