BACKGROUND: Despite increased popularity of the direct anterior approach (DAA) for total hip arthroplasty (THA), current practice trends and specific driving factors leading to adoption are not well established. METHODS: We conducted an electronic e-mail survey of members of the American Association of Hip and Knee Surgeons inquiring into the choice of THA surgical approach, perceptions of clinical outcomes, and economic implications associated with the DAA. RESULTS: Of 996 total respondents (44.3% American Association of Hip and Knee Surgeons member response rate), 56.2% currently perform the DAA. DAA performers have been in practice for statistically less time than non-performers (17.0 years vs 20.9 years, P < .001). Similarly, high-volume DAA surgeons have been in practice for less time than low-volume surgeons. DAA performers felt that revision case status (79.3%), complex anatomy (65.0%), and body habitus (53.0%) were factors leading to preferential use of the posterior approach. We also provide comprehensive data for perceived outcomes comparing the DAA and posterior approach. For current non-performers, the top reasons for not utilizing the DAA were feelings of worse outcomes, no clinical benefit, and concern for the learning curve. Economically, 76.1% of DAA performers reported increased patient market share by performing the DAA while 65.8% of non-performers endorsed lost patient market share. Only 3.0% of current non-performers plan to adopt the DAA in the future. CONCLUSION: This is the first study of its kind to highlight current trends and clinical practices from a surgeon perspective regarding the DAA. Specifically, it provides comprehensive data regarding perceptions of clinical outcomes, practice economics, and driving factors for choice of surgical approach for surgeons who do and do not perform the DAA.
