Labral tear is associated with increased risk of osteoarthritis – A cross-sectional study

Journal of Orthopaedic Reports, 2023
Introduction: The significant risk factor for hip OA is abnormal joint morphology. Labral tear occurs secondary to femoroacetabular impingment and decreases the ability of joint to maintain normal synovial fluid pressure.
