Extended offset stems are infrequently required in anterior approach total hip arthroplasty and low usage does not compromise stability.

Introduction: Extended offset (EO) stems are commonly used in posterior approach (PA) total hip arthroplasty (THA), but usage rates and complications are not well studied with anterior approach (AA) THA. This study evaluated usage rates, radiographic outcomes and complications following AA THA between patients receiving EO stems and a matched cohort receiving standard offset (SO) stems.

Materials And Methods: This retrospective review evaluated 1515 consecutive AA THA performed between 2014 and 2021.
