A glenolabral articular disruption (GLAD) lesion is a nondisplaced superficial tear of the anterior-inferior labrum that is accompanied by injury to the adjacent articular cartilage. The articular cartilage injury may range from fibrillation to a depressed osteochondral defect.
A GLAD lesion is thought to result from a forced adduction of the shoulder with the arm in abduction and external rotation.
