摘要
Objective:To review the literature regarding diagnosis and treatment of labral tear.Data sources:A systematic search was performed in PubMed using various search terms and their combinations including hip, labrum, acetabular labral tear, arthroscopy, diagnosis, and anatomy.Study selection:For each included study, information regarding anatomy, function, etiology, diagnosis, and management of acetabular labral tear was extracted.Results:Five hundred and sixty abstracts about anatomy, function, etiology, diagnosis, and management of acetabular labral tear were reviewed and 66 selected for full-text review.The mechanism of labral tear has been well explained while the long-term outcomes of various treatment remains unknown.Conclusions:Labral tear is generally secondary to femoroacetabular impingement, trauma, dysplasia, capsular laxity, and degeneration.Patients with labral tear complain about anterior hip or groin pain most commonly with a most consistent physical examination called positive anterior hip impingement test.Magnetic resonance arthrography is a reliable radiographic examination with arthroscopy being the gold standard.Conservative treatment consists of rest, non-steroidal anti-inflammatory medication, pain medications, modification of activities, physical therapy, and intra-articular injection.When fail to respond to conservative treatment, surgical treatment including labral debridement, labral repair, and labral reconstruction is often indicated.
