Midterm Functional and Structural Outcomes of Large/Massive Cuff Tears Treated by Arthroscopic Partial Repair.

Background: Previous studies have shown good clinical outcomes in patients with irreparable large or massive rotator cuff tears treated using arthroscopic partial repair (APR); however, few studies have evaluated both functional and structural outcomes in these patients.

Purpose: To evaluate both functional and structural outcomes in patients with large or massive rotator cuff tears treated using APR.

Study Design: Case series; Level of evidence, 4.
