Aims. Prosthetic joint infections (PJIs) of the hip and knee are associated with significant morbidity and socioeconomic burden. We undertook a systematic review of the current literature with the aim of proposing criteria for the selection of patients for a single-stage exchange arthroplasty in the management of a PJI. Material and Methods. A comprehensive review of the current literature was performed using the OVID-MEDLINE, EMBASE, and Cochrane Library databases and the search terms: infection and knee arthroplasty OR knee revision OR hip arthroplasty OR hip revision, and one stage OR single stage OR direct exchange. All studies involving fewer than ten patients and follow-up of less than two years in the study group were excluded as also were systematic reviews, surgical techniques, and expert opinions. Results. The initial search revealed 875 potential articles of which 22 fulfilled the inclusion and exclusion criteria. There were 16 case series and six comparative studies; five were prospective and 14 were retrospective. The studies included 962 patients who underwent single stage revision arthroplasty of an infected hip or knee joint. The rate of recurrent infection ranged from 0% to 18%, at a minimum of two years’ follow-up. The rate was lower in patients who were selected on the basis of factors relating to the patient and the local soft-tissue and bony conditions. . Conclusion. We conclude that single-stage revision is an acceptable form of surgical treatment for the management of a PJI in selected patients. The indications for this approach include the absence of severe immunocompromise and significant soft-tissue or bony compromise and concurrent acute sepsis. We suggest that a two-stage approach should be used in patients with multidrug resistant or atypical organisms such as fungus

Aims

Prosthetic joint infection (PJI) remains a serious complication that is associated with high morbidity and costs. The aim of this study was to prepare a systematic review to examine patient-related and perioperative risk factors that can be modified in an attempt to reduce the rate of PJI.

Materials and Methods

A search of PubMed and MEDLINE was conducted for articles published between January 1990 and February 2018 with a combination of search terms to identify studies that dealt with modifiable risk factors for reducing the rate of PJI. An evidence-based review was performed on 12 specific risk factors: glycaemic control, obesity, malnutrition, smoking, vitamin D levels, preoperative Staphylococcus aureus screening, the management of anti-rheumatic medication, perioperative antibiotic prophylaxis, presurgical skin preparation, the operating room environment, irrigant options, and anticoagulation.

Sinus-track cultures were compared prospectively with cultures from operative specimens in 55 patients with chronic bone infection. There was a total of 115 operative isolates; 102 of the sinus-track isolates were identical (88.7%), showing a specificity of 95.7% and a predictive value of 90.3%. A sinus-track specimen proved to be a reliable source for the isolation of all bacteria causing chronic bone infection except Staphylococcus epidermidis, provided that material from the depths of the sinus was aspirated by syringe from an active flowing sinus and inoculated immediately on culture media. Cotton-swab sinus specimens were unreliable for the isolation of mycobacteria, and could miss many pyogenic bacteria, or contain contaminants. Tuberculous bone infection should be suspected if there is no growth of any pyogenic bacteria or if there is growth of Staphyloccocus epidermidis alone on routine aerobic and anaerobic sinus cultures. Mycobacteria can often be identified from sinus-track culture from patients in whom operative culture, histopathology and clinical examination have failed to confirm the diagnosis of tuberculosis
