© 2019, Hospital for Special Surgery. Background: Return to work after shoulder arthroplasty for glenohumeral osteoarthritis (OA) is an important consideration for an aging workforce. Questions/Purposes: The aim of this study was to compare the shoulder function, pain levels, and rate of return to work in patients treated with anatomic total shoulder arthroplasty (aTSA) versus humeral hemiarthroplasty (HHA). Methods: A retrospective review of consecutive HHA patients was performed of our institution’s shoulder arthroplasty registry. Inclusion criteria were pre-operative diagnosis of end-stage OA and more than 2 years’ follow-up. HHA patients were statistically matched to aTSA patients and then screened for pre-operative work status; 26 HHA and 23 aTSA patients worked before surgery. There was no difference in average age (HHA, 62.4 years; aTSA, 61.7 years) or follow-up (HHA, 67.5 months; aTSA, 66.9 months). Results: Average American Shoulder and Elbow Surgeons (ASES) scores (HHA, 37.6 to 70.3; aTSA, 35.6 to 80.1) and visual analogue scale (VAS) for pain scores (HHA, 6.1 to 2.3; aTSA, 6.5 to 0.6) improved in both groups. However, HHA patients had worse final VAS scores, and aTSA patients were more satisfied (100% vs 77%); 61.5% of HHA patients returned to work post-operatively versus 87.0% of aTSA patients. There was no difference in time to return to work (HHA, 1.9 ± 2.3 months; aTSA, 1.3 ± 1.0 months). Conclusion: Patients with shoulder OA undergoing aTSA have higher rates of return to work, function, and satisfaction than those undergoing HHA.
