Abstract
The position of this surgeon is that there is no approach that provides superior outcomes for total hip replacement (THR). The direct anterior approach (DAA) has become popular with patients because of marketing by companies, misinformation given to journalists for public consumption, and yes, some surgeons. Because of patient pressure generated by this marketing there has been pressure on surgeons to convert their surgical approach for perceived protection of their practice. Unfortunately, the leaders of orthopaedic organizations have not countered this marketing with education of the public that there is NO scientific evidence to support DAA superiority. These orthopaedic organizations exist to be advocates for their members but have abdicated that responsibility. Whatever happened to the time honored belief of choosing a surgeon to do your operation? Instead we now choose an approach? Do anterior surgeons think that they are immune to the Bell Curve of talent? The fact is that there is NO outcome data of DAA with the longest follow up study being one year, and recent data from both coasts of the USA raise concerns with more failures from loosening of the femoral component. How in the world can we bamboozle patients about better results when there are no published results with the DAA except for recovery? The mini-posterior approach has data for all aspects of its use. Short term data shows rapid recovery and hospital discharge can be the same day; gait studies show A quality at six weeks (so does this mean that cut muscles recover quickly?). Dislocation rates are equal in most comparative studies, but I believe this favors the DAA, however, fractures are 3X greater with DAA. Data from the Mayo Clinic comparative studies showed posterior patients return to work faster! There are two 10 year studies of mini-posterior patients which show some of the best 10 year results in the literature. And there are superior technical surgeons who perform this operation to the benefit of their patients, and they should not need to suffer the implicit bias from DAA marketing that their care of patients is inferior.
