Arthroscopic diagnosis of ruptured acetabular labrum

Abstract

We performed arthroscopy in nine hips in 8 patients with hip pain of unknown origin. Of them, 5 patients had a rupture in the posterior or posterosuperior labrum, not seen by arthrography. On physical examination the patients complained of pain on both passive flexion and internal rotation of the hip, and when the thigh was pushed backwards at 90 degrees of flexion.
