How has arthroscopic management of the iliopsoas evolved, and why? A survey of high-volume arthroscopic hip surgeons.

The rapid growth of hip preservation has left surgeons following trends based on limited, or even anecdotal, evidence in certain circumstances. A consensus as well as high-level research on how best to manage the iliopsoas is lacking. Arthroscopic treatment of the iliopsoas may be an example of how treatment patterns and trends can shift with limited evidence-based medicine. A cross-sectional survey of 16 high-volume hip preservation surgeons was conducted to gather perspectives and opinions on how and why the arthroscopic management of the iliopsoas has evolved. All participants completed the survey in person and anonymously. Of the surveyed surgeons, the mean career hip preservation volume was 1031.25 cases (250 to >3000) with an average annual volume of 162.08 cases (75-400). Of the surveyed surgeons' caseload, 16.1% involved an iliopsoas tenotomy or fractional lengthening mostly commonly (75%) for recalcitrant internal snapping. Labral repair/reconstruction is performed concomitantly 87.5% of the time. Seventy-five percent of surgeons indicated a decrease in frequency of iliopsoas tenotomy over the course of their practice most commonly (56.3%) because of hip flexion weakness; however, 0% of the surgeons could cite literature evidence to support their practices. poor outcomes in individual practices was the most common (56.3%) source of this complication. Surgeons were less inclined to perform tenotomy on patients with borderline dysplasia (75%) or ligamentous laxity (56.3%).
