About

Data from large prospective cohort studies of prosthetic joint infections are lacking.

Aim of this study: analyzing prospectively the incidence of reinfection in patients with prosthetic hip infections who underwent surgery and received antibiotic therapy.

Hypothesis: to confirm in a large group that the incidence of reinfection after excision -synovectomy in acute prosthesis hip infection is 30% and 15% for chronic infection after exchange arthroplasty (one or two stage exchange).
