Clinical and Radiological Outcomes in Arthroscopic Repair of Shoulder Rotator İnterval Lesions

Rotator interval (RI) lesions (anterior-superior tears) represent a special subset of rotator cuff (RC) tears. In these lesions, pathology is localised to anterior structures, and they always present with supraspinatus tear, biceps tendon pathology and subcapularis tear (1). They were classified as type A tears by Collins et al. (2). RI lesions are thought to account for 4% of all RC tears. A small number of articles have been published in the literature, due to the rare occurrence of them compared with posteriorsuperior tears. It is suggested that natural course and prognosis are worse than conventional supraspinatus and infraspinatus tears or isolated subcapularis tears (1). Good results are reported in arthroscopic treatment of subcapular tears (3), for this reason, it is thought that RI lesions with similar patho-anatomy will have good results with arthroscopic treatment (3,4). However, due to ABSTRACT
