DAIR procedure is well established for Prosthetic Joint Infection (PJI) in acute setting after total hip and knee replacements. We present our experience of DAIR following hip and knee replacements in a District General Hospital (DGH), where we delivered comparable results to leading tertiary centres in short to mid-term followup.

We undertook a retrospective study involving 14 patients, who underwent DAIR in our DGH between August 2012 and December 2015. Patient cohort included primary, complex primary and revision hip and knee replacements. Microbiological support was provided by a Microbiologist with interest in musculoskeletal infections.

14 patients [9 males, 5 females; age 62 to 78 years (Mean 70.7); BMI 22 to 44.2 (Mean 33.8)] with multiple comorbidities underwent DAIR procedure within 3 weeks of onset of symptoms. 12 out of 14 grew positive cultures with two growing Vancomycin resistant Enterococci. Intravenous antibiotics were started after multiple samples intraoperatively and continued in six patients after discharge, while 8 were discharged with oral antibiotics. One patient died of overwhelming intraoperative septic shock in postoperative period. Another patient died of myocardial infarction subsequently. 12 (85.7%) patients were doing well with regular followup (Mean 20 months).

With good patient selection, DAIR is a far simpler solution and a safe and reproducible surgical option for early PJI following hip and knee replacements compared to one or two stage revisions. But published data in contemporary literature is predominantly from specialised centres. Our small series provides a perspective of comparable early to mid-term results of DAIR from DGH.

OBJECTIVE

Debridement, Antibiotics and Implant Retention (DAIR) procedure is well established for Prosthetic Joint Infection (PJI) in acute setting after total hip and knee replacements. We present our perspective of DAIR in a relatively a small cohort following hip and knee replacements in a District General Hospital (DGH) in United Kingdom, where we delivered comparable results to leading tertiary centers in short to mid-term followup.

Debridement Antibiotics Implant Retention (DAIR) is a recognised procedure in the management of acute prosthetic joint infection (PJI). We present an experience of DAIR following hip and knee replacements in a District General Hospital.

A retrospective review of 14 patients who underwent DAIR procedures between August 2012 and December 1015 were collated. The cohort included primary, complex primary and revision hip and knee replacements. All patients received multidisciplinary care with surgery performed by one of two arthroplasty surgeons.

9 males and 5 females with age 62 − 78 years (Mean 70.7) and BMI 22–44.2 (Mean 33.8) with various co-morbidities underwent DAIR. Surgical criteria required DAIR to be performed within 3 weeks of the onset of symptoms of infection. The time from index surgery however ranged from 15 days to 58 months. 12 of 14 grew positive cultures including two growing Vancomycin Resistant Enterococcus. Intravenous antibiotics were commenced after intraoperative samples and tailored OPAT. Antibiotic schedule varied from six weeks to eight months. 12 (85.7%) patients remain under follow up. Mean follow is 20 months (RANGE 6months-3years10months) with no recurrence of infection or reoperation.

With appropriate patient selection, DAIR is safe and reproducible surgical option in PJI in hip and knee replacements, avoiding the implications of a one or two stage revision. Published Data in contemporary literature is predominantly from specialised centres. Our small series provides a perspective of early to mid term results of DAIR to DGH. Interestingly each procedure is categorised as a failed implant on the National Joint Register.
