Subscapularis tear was graded according to the Nove-Josserand et al.20 Grade 0, normal tendon; grade 1, tear less than one-quarter; grade 2, tear more than one-quarter but not complete; and grade 3, complete tear †Tendon grade assesses rotator cuff quality using three gross tendon criteria;[14] (1) fraying over half of the tendon thickness; (2) delamination of the supraspinatus tendon, and (3) thinning of less than half of the normal thickness. A, none of these criteria were met; B, fraying or delamination was identified; and C, both fraying and delamination or thinning regardless of the other criteria ‡GT coverage evaluates the repair quality. A, complete coverage of the original footprint; B, incomplete coverage more than half of the footprint; C, incomplete coverage less than half of the footprint; and D, the presence of defect into the glenohumeral joint §Tangent sign assesses muscle atrophy of the supraspinatus. Grade 1, negative, which means that the superior border of the supraspinatus was superior to the line tangential to the coracoid and scapular spine; grade 2, borderline, which means that the superior border was located about the tangential line; grade 3, positive, which means that the superior border was inferior to the tangential line. ǁOccupation ratio means the ratio of the CSA of the supraspinatus to the fossa. Grade 1, 0.6 to 1; grade 2, 0.4 to 0.6; grade 3, < 0.4. fRCT a full-thickness rotator cuff tear, pRCT a partial-thickness rotator cuff tear, SLAP II+ superior labral anterior and posterior lesion 2 and above, SB subscapularis, P:S:M:L:MSV small:medium:large:massive, StoS side-to-side repair, GT greater tuberosity, GFDI global fatty degeneration index
