ABSTRACT
Background:
Prosthetic joint infections (PJIs), while rare, are a devasting complication of both total joint arthroplasty (TJA). With most patients undergoing surgical treatment for PJI, options vary between one-stage or two-stage (the gold standard) procedures. Debridement, antibiotics, and implant retention (DAIR) procedures are a common, less morbid alternative to two-stage revisions, but patients undergoing DAIR procedures more often experience reinfections. This is likely in part due to non-standardized irrigation and debridement (I&D) methods within these procedures. Furthermore, DAIR procedures are often desired due to their cost effectiveness and lesser operative times, but no investigations have occurred regarding operative-time-based outcomes. This study aimed to compare reinfection incidence with procedure time in DAIR procedures. In addition, this study aimed to introduce the novel Macbeth Protocol for the I&D portion of DAIR procedures and assess its efficacy.Methods:
Records of unilateral DAIR procedures for primary TJA PJI performed by arthroplasty surgeons from 2015-2022 were retrospectively reviewed for patient demographics, select medical history, body mass index (BMI), joint, microbiology, and follow-up data. In addition, a single surgeon's DAIR procedures (for primary and revision TJA) were reviewed and use of The Macbeth Protocol was noted.Results:
A total of 71 patients (mean age 64.00 ± 12.81 years) who underwent unilateral DAIR were included. Patients with reinfections following their DAIR procedure had significantly (p = 0.034) lower procedure times (93.72 ± 15.01 min) compared to those without reinfections (105.87 ± 21.91 min). Twenty-two patients underwent 28 DAIR procedures by the senior author, where 11 (39.3%) DAIR procedures utilized The Macbeth Protocol. The use of this protocol did not significantly affect reinfection rate (p = 0.364).Conclusion:
This study concluded that increased operative time led to less reinfections for DAIR procedures treating unilateral primary TJA PJIs. Additionally, this study introduced The Macbeth Protocol, which demonstrated promising potential as an I&D technique despite not showing statistical significance. Arthroplasty surgeons should not sacrifice patient outcomes determined by reinfection rate for decreased operative time. Level of Evidence III.Key words
