Which structures are involved in Arthroflex attachment during SCR?

• A. Superior Glenoid and Supraspinatus
• B. Inferior Glenoid and Infraspinatus
• C. Coracoid process and Subscapularis
• D. Glenoid rim and Supraspinatus

Answer: (A)

The graft in a superior capsule reconstruction with ArthroFlex is placed to recreate the superior capsule, so it has a medial fixation on the superior glenoid rim and a lateral fixation at the footprint of the supraspinatus on the greater tuberosity. Fixing medially to the superior glenoid provides a stable anchor in the joint’s superior aspect, while anchoring laterally at the supraspinatus footprint (the area where the supraspinatus tendon attaches) creates the necessary restraint to keep the humeral head from migrating upward when the rotator cuff is deficient. Attaching to other structures, like the inferior glenoid, coracoid, or subscapularis, would not reproduce this specific superior restraint or align with how SCR grafts are intended to function.
