Otto Aufranc Award: Dual-mobility Constructs in Revision THA Reduced Dislocation Rerevision and Reoperation Compared With Large Femoral Heads

摘要

BackgroundDislocation is one of the most common complications after revision THA. Dual-mobility constructs and large femoral heads (ie, 40 mm) are two contemporary, nonconstrained bearing options used in revision THA to minimize the risk of dislocation; however, it is not currently established if there is a clear benefit to using dual-mobility constructs over large femoral heads in the revision setting.
