This study states that Reverse total shoulder replacement (TSR) in elderly patients with primary osteoarthritis (OA) and rotator cuff pathology is increasingly being performed. The purpose of our study was to determine the medium-term results of anatomic TSR for OA in patients with established preoperative partial-thickness rotator cuff tears on magnetic resonance imaging (MRI) scans. We reviewed a cohort of patients who had undergone anatomic TSR for OA with a preoperative MRI diagnosis of partial-thickness rotator cuff tear. Patients were assessed with preoperative and post operative Oxford Shoulder Scores, evaluation of their range-of-movement and clinical rotator cuff assessment. Anteroposterior and axillary radiographs were used to assess for any proximal humeral migration (using the Torchia classification) and any evidence of loosening. The Lazarus score was used to grade glenoid radiolucencies.

The study comprised 36 patients (14 men and 22 women) who underwent TSR and had partial-thickness rotator cuff tears on MRI; preoperatively, all showed mild to moderate fatty infiltration.
