Retrospective cohort study using Medicare 5% national sample data (1997–2006) to quantify PJI incidence and identify independent risk factors in 69,663 elective TKA patients followed up to 10 years, using Cox regression and Kaplan-Meier analysis.
When consenting a Medicare-age patient for TKA, quote a ~1.55% two-year infection risk and flag male sex, high comorbidity burden, prolonged operative time, and low socioeconomic status as compounding factors — each is independently actionable (optimize comorbidities preoperatively, plan for efficient surgical execution) and all predict risk better than where the surgery is done.
