Abstract

To identify factors associated with ease of hip distraction at the time of hip arthroscopy.A retrospective review of patients 17-50 years old undergoing hip arthroscopy with a single high-volume hip arthroscopist was performed from 2014 to 2020. Demographics, clinical history, examination, and imaging findings were collected. Distractibility was quantified using turns of fine traction (1 turn?=?4 mm axial distraction) with the patient paralyzed on a fracture table with a well-padded perineal post Fine axial traction was applied after the patient's perineum contacted the post. Demographic and clinical predictors of ease of distractibility were analyzed with simple linear regression models. Significant predictors were subsequently added to a multivariable linear regression model, estimating the effect of each variable.In total, 453 patients were included, with an average age of 31.6 years (±?9.2) and 45.9% females. In univariate analysis, gender, race, BMI, range of motion, hyperextension-external rotation (HEER) test, the abduction-extension-external rotation test, and lateral center edge angle (LCEA) were associated with the number of fine traction turns required to distract the hip. On multivariable analysis, lower LCEA (p?=?0.002), female gender (p?
