The importance of the rotator interval in glenohumeral instability has
become increasingly apparent as anatomic studies have illustrated a s
ignificant increase in inferior and posterior translations after secti
oning of the coracohumeral and superior glenohumeral ligaments. Limite
d reports of this lesion exist in the literature, and all such lesions
have been treated with open procedures, with good clinical results. T
his report describes an arthroscopic technique for imbrication of the
rotator interval in treating symptomatic defects and laxity in the ant
erosuperior shoulder capsule.
