Creating a model for the direct anterior approach in hip replacement surgery
Official title: Modeling and Workflow Recognition for the Anterior Approach in Total Hip Arthroplasty
Run by Balgrist University Hospital · NCT05993845 · Data updated 2026-11-12
This study is trying to break down the steps of a specific hip replacement surgery technique to see if it can make the surgery easier and help patients recover better.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients scheduled for primary total hip arthroplasty at the participating hospitals.
✕Probably not a fit
Patients who have had previous hip surgery or those with hip or pelvis fractures at the site of the THA may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to systematically describe the surgical process for the direct anterior approach (DAA) in total hip arthroplasty (THA) by segmenting a labeled dataset of THA surgery videos into individual surgical steps and sub-steps. The project utilizes surgical process models (SPMs) to manage and optimize the surgical workflow, allowing for comparisons between different interventions and surgical teams. By analyzing the complexities of the DAA, the study seeks to enhance surgical efficiency and improve patient outcomes.
Why it matters
Potential benefit: If successful, this study could lead to improved surgical techniques and outcomes for patients undergoing total hip arthroplasty.
How similar studies have gone: While the approach of using surgical process models is innovative, similar studies have shown promise in optimizing surgical workflows and improving outcomes.
