Prosthetic joint infection (PJI) is a much feared complication to arthroplasty with significant patient morbidity. Rifampin is increasingly used in staphylococcal PJIs treated with debridement and retention of the prosthesis. The evidence supporting rifampin combination therapy in PJIs is limited due to the lack of controlled studies. The aim of this study is to evaluate the effect of adding rifampin to conventional antimicrobial therapy in early staphylococcal PJIs treated with debridement and retention. In this multicentre randomized controlled trial, 99 patients with PJI after hip and knee arthroplasties were enrolled. All patients underwent a standardized surgical debridement. 65 patients had PJI caused by staphylococci and further included in the study. They were randomly assigned to receive rifampin or not in addition to standard antimicrobial therapy with cloxacillin, or vancomycin in case of methicillin resistance. They received parenteral antibiotics for two weeks, then oral antibiotics for 4 weeks. In case of methicillin resistance, vancomycin was administered i.v. for 6 weeks. The primary end point was no signs of infection after 2 wears follow-up.Aim

The incidence of prosthetic joint infections can be severe to monitor, as they are rare events. Recent publications from National registries points toward a significant underestimation of reported infections. The aim of this project was to develop a complication register that could report the “true” and momentaneous incidence of prosthetic infections after total knee and hip arthroplasty. All patients operated with total hip arthroplasty (THA) or total knee arthroplasty (TKA) at our hospital were included in a local quality registry. All complications were reported at follow-up at 2 and 3 months for total knee and hip arthroplasties respectively, and at 1-year follow up. Both primary and revision surgeries were included. In order to monitor complications of special interest, such as deep postoperative infections, key variables were presented in a g-chart. This chart shows the number of uncomplicated surgeries between each complication (such as infection) in a bar diagram. This diagram is easily read as high bars indicate a low incidence of complications and low bars indicate a high incidence. The diagram is updated and distributed for information every month.Aim
