The Arthroflex graft in SCR is attached to the Superior Glenoid and which rotator cuff muscle?

• A. Subscapularis
• B. Infraspinatus
• C. Teres Minor
• D. Supraspinatus

Answer: (D)

The key idea is recognizing where the SCR graft is anchored laterally to recreate the superior capsule. In this procedure, the graft is fixed medially to the superior glenoid and laterally at the footprint of the supraspinatus tendon on the greater tuberosity. This location aligns the graft with the superior capsule and provides a restraint against upward (superior) migration of the humeral head when the rotator cuff is deficient. The other rotator cuff muscles insert at different locations (subscapularis to the lesser tuberosity, infraspinatus and teres minor posterior aspects of the greater tuberosity), so their footprints aren’t used as the lateral anchor in this reconstruction.
