Magnetic resonance arthrography is the current method of choice for investigating patients with a clinical diagnosis of femoroacetabular impingement prior to performing hip arthroscopy. The aim of our study was to assess the efficacy of this investigation by comparing the findings of MR arthrogram with those found at arthroscopy, with reference to labral tears and chondral damage. A prospective trial to investigate the sensitivity, specificity, accuracy and predictive value of MRA for diagnosis of labral tears and chondral defects. Over a 25-month period 69 hips undergoing hip arthroscopy were investigated with MRA prior to the definitive operative procedure. MRA findings were compared to the intraoperative findings.Background
