Matched Cohort Study Comparing Arthroscopic-Assisted Versus Full-Arthroscopic Latissimus Dorsi Tendon Transfer for Irreparable Massive Rotator Cuff Tears.

Equivalent outcomes at minimum 24-month follow-up were found for arthroscopic-assisted and full-arthroscopic LDTT in terms of complications rates (15.4% and 13.2%, respectively), conversion to reverse shoulder arthroplasty (5.7% and 5.2%), clinical scores, and range of motion.
