A Modified Mason-Allen Suture Enhancement Technique (Sunglasses Loop) for Single-Row Repair of Medium-to-Large Rotator Cuffs.

We propose a single-row repair method for medium-to-large rotator cuff rotator cuff tears using a modified Mason-Allen suture enhancement technique (sunglasses loop), which uses high-tensile modified Mason-Allen sutures to close the medial rotator cuff tissues to form a sunglasses loop, resets the rotator cuff tissues via traction with the high-tensile suture, repairs the rotator cuff in a single row with triple-loaded suture anchor (anchor with 3 high-strength sutures), and finally employs an outer row of staples to secure the suture to the lateral aspect of the greater tuberosity, preventing the tendon from pulling out. This method uses a special sunglasses-shaped suture loop, which produces an increase in holding power and a reduction in tension relative to other single-row repair techniques and reduces the rate of rotator cuff retear.
