Trends in cup position utilizing computer-assisted navigation during total hip arthroplasty: A retrospective observational study

Conclusions: Our data show that while most acetabular cups were placed within the traditional safe zones, the mean anteversion orientation is considerably higher than those suggested by the Lewinnek and Callanan safe zones. The implications of this observation warrant further investigation. Level of Evidence: Level III.
