Perineal Pressure During Hip Arthroscopy Is Reduced by Use of Trendelenburg: A Prospective Study With Randomized Order of Positioning.

Background: The use of traction during hip arthroscopy is commonly used to provide safe joint access and to improve visualization. However, traction during hip arthroscopy has been associated with complications ranging from transient neuropraxias to devastating soft-tissue necrosis. Trendelenburg positioning may be helpful, but the degree to which this is true is not well understood.

Prevalence of Generalized Ligamentous Laxity in Patients Undergoing Hip Arthroscopy: A Prospective Study of Patients' Clinical Presentation, Physical Examination, Intraoperative Findings, and Surgical Procedures.

Background: Recent studies identified microinstability in the hip as a pathoetiology of painful hip conditions, and it was proposed that generalized ligamentous laxity conditions may predispose patients to such microinstability.

Purpose: To study the relationship of generalized ligamentous laxity with patient characteristics, clinical presentation, intraoperative findings, and surgical treatments in a cohort of patients undergoing hip arthroscopy.

Study Design: Cross-sectional study; Level of evidence, 3.
