- W3132368224 abstract "Since the introduction of shoulder arthroplasty, the indications have been expanding. Because of the increasing number of arthroplasty procedures, revision surgeries are also inevitable. The purpose of our study is to delineate a large number of revision shoulder arthroplasty cases treated in different ways, including antibiotic spacer placement (ABX), hemiarthroplasty (HA), anatomic total shoulder arthroplasty (aTSA), and reverse total shoulder arthroplasty (rTSA), and to analyze the relationship between preoperative factors and clinical outcomes. We reviewed our institution's records of revision shoulder arthroplasty between January 1, 2000, and October 1, 2017. Preoperative information included age at the time of surgery, gender, body mass index, and infection status. Pre- and postoperatively, we gathered 6 patient-reported clinical outcomes and 3 range-of-motion parameters (elevation, abduction, and external rotation). Postoperative complications were also assessed. Then, we examined the differences between the pre- and postoperative outcomes. As a secondary analysis, we performed multivariable regression analysis on the same outcomes, accounting for age at the time of surgery, infection status, and previous surgery type. Among the 341 revisions performed, 138 cases met inclusion criteria of at least a 2-year follow-up with pre- and postoperative functional outcome scores. The majority of our revision procedures were to a rTSA (92 cases, 67%), followed by aTSA (28 cases, 20%), and ABX/HA (18 cases, 13%). The mean age at the time of our index surgery was 66 years old. In aTSA and rTSA, all the postoperative outcomes (ie, ASES, Constant, UCLA, SST, SPADI, SF-12 scores, and 3 AROMs) were significantly improved beyond the minimal clinically important difference (MCID) except SF-12 scores in aTSA ( P = .25) and active external rotation in rTSA ( P = .73). None of the ABX/HA's postoperative outcomes achieve significant improvement or MCID. Multivariable regression analysis showed that older age at the time of surgery was significantly associated with better outcomes in 3 of the 6 patient-reported outcomes (ASES, SST, and SPADI; P = .023, .023, and .028, respectively). Revision aTSA and rTSA showed statistically and clinically significant improvement postoperatively. ABX and HA did not achieve meaningful postoperative improvement. Overall, patients getting revision shoulder arthroplasty at an older age had better patient-reported outcomes. Level III; Retrospective Cohort Study" @default.
