N2 - Background: Interpretation of anchor-based clinical differences in the context of pain and functional change remains undefined. The purpose of this study was to characterize American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores for patients after anatomic total shoulder arthroplasty with minimum 1 year of follow-up in terms of pain and change in each functional element on the ASES. Methods: We performed a retrospective study of a prospective institutional patient database of primary anatomic total shoulder arthroplasties from 2017-2020 with baseline and 1-year postoperative ASES scores. Three clinical outcome groups were established using an anchor-based global rating of change assessment: minimal clinically important difference (MCID), moderate clinical benefit (MCB), and substantial clinical benefit (SCB). Pain and functional outcomes in each group where then characterized and compared. Results: A total of 67 patients were analyzed in terms of demographics and clinical outcomes. Two-thirds (65%) of patients achieved the SCB, 24% achieved the MCB, and 10% achieved the MCID. Washing, reaching for a shelf, and throwing were the most common functional deficits experienced preoperatively and accounted for the largest improvement in function postoperatively. Patients in the MCID group had higher preoperative visual analog scale (VAS) pain scores (7.1 ± 3.0) than the MCB (5.8 ± 2.5) or SCB (5.8 ± 2.2) groups (P = .0612). The MCID group had the least amount of preoperative functional deficits when compared to the MCB and SCB groups (P = .041). Postoperative VAS pain scores improved by 5.1 in the SCB, 3.6 in the MCB, and 3.7 in the MCID groups. Functional change in each element of the ASES improved by 1.4/4 in the SCB, followed by 0.9/4 in the MCB group and 0.05/4 in the MCID group (P < .001). Conclusion: The MCID group had higher preoperative pain scores and the least amount of preoperative functional deficits when compared to the MCB and SCB groups. The MCID was realized through pain improvement only, whereas the MCB and SCB consisted of meaningful improvements in pain and function.
