Method From January 2000 to December 2012, 45 patients undergoing THA and TKA who developed PJI were recruited for case subjects; controls were 252 without PJI, matched by year of index for surgery and type of surgery. Conditional logistic regressions were run to compute odds ratios (ORs) and 95% confidence intervals (CIs). Results Demographic factors and comorbid conditions associated with an increased adjusted risk of PJI (in decreasing order of significance) were diabetes (OR = 5.47, 95% CI: 1.77每16.97; p = 0.003), age (65每75 vs. 45每65 years) (OR = 3.36, 95% CI: 1.30每8.69; p = 0.013), BMI (≡28 vs. 18.5每28 kg/m2) (OR = 2.77, 95% CI: 1.20每6.40; p = 0.017), place of residence (rural) (OR = 2.63, 95% CI: 1.13每6.10; p = 0.025) and alcohol abuse (OR = 2.95, 95% CI: 1.06每8.23; p = 0.039). Conclusion Patients with diabetes, older age, BMI of ≡28 kg/m2 and alcohol abuse or living in rural areas, had increased PJI risk. Additional systematic large-scale studies are needed to verify these results. %U http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0095300
