2. Fig 1
Axial T2 magnetic resonance imaging cuts should be critically examined for evidence of subscapularis tears. In this case, fiber disruption with high signal intensity is seen at the upper subscapularis tendon insertion (arrow).

3. Fig 2
Visualization of the upper subscapularis footprint shows (A) no overt tear, although (B) linear longitudinal tearing is indicative of subcoracoid impingement and often associated with partial-thickness tearing at the footprint. (H, humeral head articular cartilage; M, medial biceps sling; S, subscapularis tendon.)

4. Fig 3
Incision of the medial sling (A) with curved arthroscopic scissors shows (B) a full-thickness upper subscapularis tendon tear (dotted arrow). The bone bed (solid arrow) has been debrided. (H, humeral head articular cartilage; M, medial biceps sling; S, subscapularis tendon.)

5. Fig 4
The subcoracoid space should be carefully inspected for impingement. (A) View with a 30° arthroscope after exposure of the coracoid-tip osteophyte (arrow). (B) View with a 70° arthroscope after osteophyte removal with a burr. (CT, coracoid tip; S, anterior subscapularis tendon.)

Final repair construct showing (A) reconstruction of subscapularis footprint with knotless FiberTape-SwiveLock construct and (B) biceps tenodesis (arrow). (GT, greater tuberosity; H, humeral head articular cartilage; S, subscapularis tendon.)
