Superior Capsular Reconstruction Versus Lower Trapezius Transfer for Posterosuperior Irreparable Rotator Cuff Tears With High-Grade Fatty Infiltration in the Infraspinatus

Abstract

Although aSCR and aLTT both provided improvements in overall clinical outcomes for posterosuperior IRCTs with high-grade 4 fatty infiltration in the infraspinatus, aLTT was superior in terms of functional improvement, patient satisfaction, progression of arthritis, and graft integrity. Therefore, we prefer aLTT for posterosuperior IRCTs under the condition of high-grade 4 fatty infiltration in the infraspinatus.
