Acetabular bone loss: Accommodating a growing void

The burden of revision total hip arthroplasty continues to rise exponentially, which is a reflection of the increasing number of primary total hip arthroplasty (THA) procedures being performed, lower surgeon thresholds for THA due to excellent mid- to long-term success rates and improved survival of the general population.
