Abstract
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.
METHODS
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. Multiple samples were taken intraoperatively for cultures and histology. mMicrobiological support was provided by a microbiologist with interest in musculoskeletal infections.
RESULTS
14 patients [9 males, 5 females; age 62–78 years (Mean 70.7); BMI 22–44.2 (Mean 33.8)] with multiple comorbidities underwent DAIR procedure within 3 weeks of onset of symptoms, (although the time from index surgery ranged from 15 days to 58 months). Patient selection was made by two Hip surgeons. 12 out of 14 grew positive cultures with two growing Vancomycin resistant Enterococcus. IV antibiotics were stated after samples intraoperatively and continued in six patients after discharge using (OPAT), while 8 were discharged with oral antibiotics. One patient died in immediate post operative period due to generalised sepsis. Another patient died of myocardial infarction 2 years after DAIR. 12 (85.7%) patients are doing well with regular followup (Mean 20 months) in clinics.
CONCLUSIONS
With good patient selection, DAIR is a far simpler solution and a safe and reproducible surgical option in PJI in hip and knee replacements compared to one or two stage revisions with the implications. But published Data in contemporary literature is predominantly from specialized centers. Our small series provides a perspective of early to mid term results of DAIR from a DGH.
