Hidden blood loss in total hip arthroplasty: A comparison of the direct anterior versus posterolateral approach

Key Points

• The aim is to compare hidden blood loss between the direct anterior and posterolateral approaches in total hip arthroplasty.
• Comparison of two surgical approaches: direct anterior and posterolateral.
• Measurement of intraoperative and hidden blood loss during surgery.
• Assessment of postoperative outcomes related to blood loss.
• Patterns of blood loss differed significantly between the two surgical approaches.
• The direct anterior approach showed reduced hidden blood loss compared to the posterolateral approach.
• Overall recovery metrics indicated more favorable outcomes for the approach with less hidden blood loss.
