Femoro-acetabular Impingement (FAI) Clinical Trial
Official title:
Change in Muscle Volume in Patients With Unilateral Femoro-acetabular Impingement Syndrome After Hip Arthroscopy
The purpose of this study was to investigate the change in muscle volume around the hip in patients with unilateral femoro-acetabular impingement (FAI) after arthroscopy.
We performed a retrospective review of magnetic resonance imaging (MRI) data of FAI patients who underwent hip arthroscopy between January 1, 2016, and July 1, 2018. "Image J" with an embedded region-of-interest (ROI) tool was used to calculate the cross-sectional area (CSA) of muscles on MRI. Wilcoxon signed-rank test was used to determine the differences between preoperative and postperative hip muscle CSA. The correlations of change in muscle CSA with age, gender, BMI, pain level, preoperative symptom duration, and multiple validated patient-reported outcomes were also analyzed with a spearman rank correlation test. ;
