Abstract
Total knee arthroplasty is a life changing operation. Although a rare complication, periprosthetic joint infection (PJI) can be a devastating event for patient and can be a challenging experience for the treating department. Management of the PJI is generally operative combined with extensive antibiotic therapy. The primary aim of treatment is to restore a functioning joint, either with debridement and retaining the well-fixed implants or with revision of part or all of the components. Whilst two stage revision arthroplasty has been considered as optimal treatment for PJI by many surgeons, Debridement, Antibiotics and Implant Retention (DAIR) could be considered as an alternative option in a selected group of patients.In this study, we review the recent literature to explore the efficacy and outcome of DAIR in PJI. We included all recent studies, which have used DAIR in PJI around total knee arthroplasty and assess for factors that would be either positive or negative towards the outcome. We particularly wanted to review role of timing of surgery and infecting organisms in outcomes of the treatment. We have also tried to identify whether patients have better functional outcome following DAIR in comparison to revision surgeries.
