Crohn Disease Linked To Periprosthetic Joint Infection Risk

A recent study published in the August issue of *Arthroplasty Today* reports that patients with Crohn disease (CD) face a higher risk of developing periprosthetic joint infection (PJI) following total joint arthroplasty. The research, which analyzed postoperative outcomes in a large cohort of arthroplasty recipients, found that the incidence of PJI among those with CD was significantly greater than in patients without the inflammatory bowel condition.

The investigators examined clinical records from multiple centers, controlling for factors such as age, sex, body mass index, and comorbidities. Their multivariate analysis revealed that CD remained an independent predictor of infection, suggesting that the systemic inflammation and immune dysregulation characteristic of the disease may compromise wound healing and implant integration. The authors recommend that surgeons consider enhanced perioperative strategies—such as preoperative optimization of nutritional status, tailored antibiotic prophylaxis, and close postoperative monitoring—for patients with Crohn disease.

These findings underscore the importance of multidisciplinary pre‑operative evaluation for individuals with CD undergoing joint replacement. By recognizing the elevated infection risk, orthopedic teams can implement targeted interventions to improve surgical outcomes and reduce complications in this vulnerable patient population.
