Outpatient versus inpatient anatomic total shoulder arthroplasty: outcomes and complications

Total shoulder arthroplasty (TSA) is an effective treatment option for glenohumeral arthritis. Historically, this surgical procedure was performed on an inpatient basis. There has been a recent trend in performing TSA on an outpatient basis in the proper candidates.

All patients who underwent outpatient TSA performed by a single surgeon between 2015 and 2017 were included. Demographic information and clinical outcome scores, as well as data on complications, readmissions, and revision surgical procedures, were recorded. This group of patients was then compared with a matched cohort of patients who underwent inpatient TSA over the same period.

Overall, 94 patients (average age, 60.4 years; 67.0% male patients) underwent outpatient TSA and were included. Patients who underwent outpatient TSA showed significant improvement in all clinical outcome scores at both 1 and 2 years postoperatively. The control group consisted of 77 patients who underwent inpatient TSA (average age, 62.6 years; 53.2% male patients). No significant differences in complications or improvements in clinical outcome scores were found between the inpatient and outpatient groups.

TSA performed in an outpatient setting is a safe and reliable procedure that provides significant improvement in clinical outcome scores and no difference in complication rates compared with inpatient TSA.
