Key clinical point: Patients with rheumatoid arthritis (RA) do not exhibit an elevated risk for acute or 1-year postoperative surgical site infection following total knee arthroplasty (TKA) compared with patients with osteoarthritis.
Major finding: The risk for surgical site infection at 90 days (adjusted odds ratio [aOR] 0.81; P = .598) and 1 year (aOR 0.463; P = .26) post-TKA was not significantly different between patients with RA and osteoarthritis.
Study details: This retrospective cohort study included patients with RA (n = 1,126) and osteoarthritis (n = 63,215) who underwent primary TKA.
Disclosures: No external funding was received for this study. The authors declared no conflict of interests.
