BACKGROUND: The purpose of this study was to describe the pathoanatomy of patients diagnosed with rheumatoid arthritis and rotator cuff deficiency and report their outcomes following reverse shoulder arthroplasty. METHODS: Twenty-one shoulders were evaluated prospectively. Nine had no prior surgery, 9 had a failed rotator cuff repair, and 3 had a failed arthroplasty. Patients were followed for a minimum of 2 years (average, 36 months). All patients had preoperative radiographs and 19 shoulders had an MRI or CT available for evaluation of muscular and bony deficiency. Radiographs at most recent follow-up were evaluated for loosening and scapular notching. RESULTS: All outcome measures improved significantly: ASES scores improved from 28 preoperatively to 82 postoperatively (P < .0001); SST scores improved from 1 to 7 (P < .0001); VAS pain scores improved from 7 to 1 (P < .0001); VAS function scores improved from 3 to 6 (P=.0058); elevation improved from 52° to 126° (P < .0001); abduction improved from 55° to 116° (P=.0002); external rotation improved from 19° to 33° (P=.02); and internal rotation improved from S1 to L4 (P=.02). Twelve patients rated their outcome as excellent, 6 as good, 2 as satisfactory, and 1 as unsatisfactory. Severe glenoid erosion was seen in 10 of the shoulders and 5 of the defects required structural grafting. Three patients (14%) sustained a complication that required reoperation: 2 for infection and 1 for periprosthetic fracture. CONCLUSIONS: In patients with rheumatoid arthritis and rotator cuff deficiency, reverse shoulder arthroplasty can provide improvement in function and decreased pain.
