Is intraarticular pathology common in patients with hip dysplasia undergoing periacetabular osteotomy?

Abstract: Periacetabular osteotomy (PAO) enables correction of bony acetabular deficiency in the setting of hip dysplasia. Patients with insufficient acetabular coverage often have intraarticular pathology, but the degree of this pathology has been incompletely characterized. We have used arthroscopy as an adjunct to PAO to further delineate intraarticular pathology in patients with hip dysplasia with mechanical symptoms.

METHODS: We reviewed all 16 patients (17 hips; mean age at surgery, 21 years; range, 12-33 years) with hip dysplasia who underwent PAOs and concomitant hip arthroscopy at our institutions from October 2010 to March 2012. During this period, 80 patients underwent PAOs, making the arthroscopic cohort 21% of the total cohort. Indications for concomitant hip arthroscopy were mechanical symptoms consistent with labral pathology identified on MRI. We documented pathology involving the labrum, chondral surface, ligamentum teres, cam deformity, and psoas tendon.
