To describe the clinical findings associated with labral ossification (LO), report the outcomes of arthroscopic treatment, and compare this condition to a control group with femoroacetabular impingement (FAI).
A retrospective review of hip arthroscopy patients from 2004 to 2013 was performed to identify patients with a diagnosis of pincer FAI with LO and at least 2 years of follow-up. Diagnosis was made by plain radiograph, computed tomography, magnetic resonance imaging, or intraoperatively. The LO cohort was compared to a chronologically matched control group of FAI patients with pincer FAI but no LO. Patients were prospectively assessed with modified Harris Hip Score (mHHS) preoperatively and then postoperatively at 3, 12, 24, 60, and 120 months.
