We compared postoperative outcomes after primary total knee or hip arthroplasty (TKA/THA) between patients prescribed tirzepatide and those prescribed semaglutide.  \nMethods  \nA retrospective cohort study was performed using the TriNetX US Collaborative Network. Adults undergoing primary TKA or THA with at least two coded prescription fills for tirzepatide or semaglutide within six months of surgery were identified, and patients taking both agents were excluded. Cohorts were propensity score matched 1:1 (2,858 per group, all standardized differences below 0 .05) . Odds ratios (OR) with 95% confidence intervals (CI) were calculated at 90 days, 1 year, and 2 years.  \nResults  \nOf 669,698 patients who underwent primary TKA or THA, 8,797 (1 .3%) had ≥ 2 tirzepatide or semaglutide prescriptions. At 90 days and 1 year, no surgical, medical, or implant-related outcome differed significantly. At 2 years, tirzepatide exposure was associated with lower odds of mechanical complications (OR 0 . 64, 95% CI 0.42 to 0 .96) and periprosthetic joint infection (PJI) (OR 0 . 64, 95% CI 0.41 to 0 .999; P = .048) . Reoperation did not differ significantly (OR 0 . 68, 95% CI 0.43 to 1 .08) .  \nConclusion  \nTirzepatide and semaglutide prescriptions were associated with similar 90 day and 1 year outcomes, while tirzepatide was associated with lower 2-year mechanical complications and PJI. The distinction between dual GIP/GLP-1 agonism and selective GLP-1 agonism may therefore carry clinical relevance, and these agents should not be presumed equivalent.  \nIntroduction  \nTotal knee and total hip arthroplasty (TKA/THA) are among the most frequently performed operations worldwide, and utilization has continued to rise across international health systems [ 1, 2] . In the United States they are among the most common and reliable orthopaedic procedures [3], and their effectiveness has prompted calls for arthroplasty to be recognized as an essential surgical service worldwide [4] .
