2017 AAOS Annual Meeting: Can a Functional Difference Be Detected in Reverse Arthroplasty with 135° vs. 155° Prosthesis for the Treatment of Rotator Cuff Arthropathy: A Prospective Randomized Study

100 patients scheduled for reverse total shoulder arthroplasty were randomized to receive a prosthesis with either a 135-degree neck-shaft angle or a 155-degree neck-shaft angle. Patients were assessed for clinical scores and incidence of complications over 1 year postoperatively. Results demonstrated no significant differences in shoulder range of motion, patient-reported pain or function between groups after 1 year. The incidence of complications was 13/50 in the 135-degree group and 4/50 in the 155-degree group.
