Aim

Acute hematogenous periprosthetic joint infection (AHI) is a diagnosis on the rise. The management is challenging and the optimum treatment is not clearly defined. The purpose of this study was to evaluate the characteristics of AHI, and to study risk factors affecting treatment outcome.

Methods

We retrospectively analysed 44 consecutive episodes with AHI in a total hip or knee arthroplasty beween 2013 and 2020 at a single center. AHI was defined as abrupt symptoms of infection ≥ 3 months after implantation in an otherwise well functioning arthroplasty. We used the Delphi criteria to define treatment failure with a minimum of 1-year follow-up.

Aim

Debridement, antibiotics and implant retention (DAIR) has become the preferred treatment in early prosthetic joint infections (PJI) and acute haematogenous PJI, but the success rates have been varying. The aim of this study was to evaluate the outcome of a high quality DAIR procedure performed according to a consistently applied surgical protocol in early PJI's and acute haematogenous PJI's in hip and knee.

Methods

We performed a prospective multicentre study in 8 hospitals in Norway. A standardized DAIR protocol was used in all patients. An empirical intravenous regimen containing cloxacillin and vancomycin was given until definitive microbiological results were known. Antibiotics were given in total for 6 weeks. The primary outcome measure was infection control. Factors that could affect the outcome were also studied.

Aim

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.

Method

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.
