Over the past three years, roughly 100,000 hip and knee replacements have been performed by the Brazilian Public Healthcare System. Prosthetic joint infection (PJI) is expected to range between 1% to 10% after primary and revisions joint arthroplasties, respectively. So far, there have been no published national PJI data which would be helpful at developing local preventive strategies and guide surgeons and clinicians. We aimed at We prospectively enrolled patients with PJI in a national cohort study among 12 hospitals from 6 different States to describe host, pathogens, diagnosis, surgery strategies adopted (according to the standard hospital-based guideline) and outcome after 1- and 2-years follow-up. PJI was defined using the IDSA criteria (Osmon D, et al. Clin Infect Dis. 2013). Patients were enrolled from July 2013 to December 2015.Aim

The incidence of posttraumatic osteomyelitis (PTO) is increasing in spite of new surgical techniques and development of new antimicrobial therapies. It has been difficult to assess outcomes of PTO because of the numerous risk factors involving the patients, trauma characteristics, surgical conditions, diversity of etiologic agents and long period of follow-up required to determine the effects of any treatment. We aim to identify factors predisposing to develop recurrence of chronic PTO. Between August 2007 and August 2012, a single-centre prospective cohort study was carried out among 193 patients with PTO following orthopaedic surgery. Bone and soft tissues were collected for cultures and PTO was defined according to CDC/NHSN criteria. Patient, injury, surgery-associated variables and microbiological records were identified for potential risk factors associated to recurrence of PTO. Univariate and multivariable analyses using logistic regression were performed, and p <0.05 was considered significant.Aim
