Abstract BACKGROUND AND OBJECTIVE: To identify the infection risk factors in knee and hip total prosthesis. METHOD: Case-control study of arthoplasties performed during 10 years. RESULTS: By means of conditional multivariate analysis, infection risk factors with greater odds ratio (OR) were surgical risk rate >or= 2, according to the National Nosocomial Infections Surveillance (NNIS) (OR, 3.3; 95\% confidence interval [CI], 1.1-10.8) and post-operative non-infectious complications (OR, 8.9; 95\% CI, 1.1-83.1) (p < 0.05). The global infection rate was 2.4\% (95\% CI, 1.6\%-3.2\%) of 1,666 joint implants. Gram-positive cocci were the principal involved microorganisms (63\%). CONCLUSIONS: A high NNIS together with non-infectious post-operative complications increase the risk of prosthesis infection.
