Skibicki HE, Post ZD, Kay AB, et al. - This study was attempted to correlate outcomes of patients with Paprosky I or II femoral bone loss undergoing revision total hip arthroplasty with either a primary metaphyseal-engaging cementless stem or a revision diaphyseal-engaging stem. Researchers conducted a retrospective analysis including a total of 70 patients with Paprosky I or II femoral bone loss who had undergone femoral revision. They compared clinical and radiographic outcomes and complications over an average follow-up of 2.9 years (SD 1.4). This study’s findings demonstrate that for revision hip arthroplasty, the use of modern primary cementless femoral stems is a viable option in the setting of preserved proximal femoral metaphyseal bone. As per the findings, outcomes are not inferior to those of revision stems and offer potential advantages.
