Increased early complication rates following total hip arthroplasty in rheumatoid arthritis patients based on a Japanese nationwide medical claims database study.

ABSTRACT: Although the rate of total hip arthroplasty (THA) is declining among rheumatoid arthritis (RA) patients, the complex etiology of RA and associated immunomodulatory therapies may contribute to elevated risks of postoperative complications. This study aimed to evaluate in-hospital complications following THA in RA patients compared to osteoarthritis (OA) patients using a Japanese nationwide database. This retrospective study analyzed data from the Diagnosis Procedure Combination database, including THA patients between December 2011 and March 2023. The RA and OA groups were matched in a one-to-three ratio using propensity scores, considering factors such as age, sex, and comorbidities. Multivariate logistic regression was conducted to assess independent risk factors for complications. Among
