This retrospective cohort study used the TriNetX global database to evaluate the association between preoperative GLP-1 RA use and postoperative outcomes after TSA.

Adult patients who underwent TSA between 2008 and 2022 were identified and stratified according to GLP-1 RA use within 30 days before surgery. One-to-one propensity score matching was performed to balance demographic characteristics and comorbidities. Outcomes included 90-day medical complications and 2-year surgical outcomes.

In the matched 90-day cohort (1,951 patients), no significant differences were observed between groups in medical complications, readmission, emergency department utilization, or all-cause mortality. In the matched 2-year (1,917 patient) cohort, GLP-1 RA use was associated with significantly lower rates of emergency department utilization (26.7% vs. 31.0%; RR 0.86; 95% CI 0.78–0.95; p = 0.012) and all-cause mortality (1.8% vs.
