ABSTRACT
BACKGROUND/METHODS:
We retrospectively reviewed 89 patients with acute prosthetic joint infection treated with debridement, antibiotics, and implant retention (DAIR) or 2-DAIR. Patients had <3 weeks of symptoms and met Musculoskeletal Infection Society criteria for infection. Sixty-three patients were treated with DAIR, whereas 26 patients were managed using a 2-DAIR protocol where patients underwent initial debridement, antibiotic bead placement, and subsequent return to the operating room at an average of 16.3 days for repeat debridement and modular component exchange. Patients received a 6-week course of intravenous antibiotics and 3 months of oral antibiotics for suppression. Demographics, comorbidities, implant retention rates, and complications were compared between the groups. The McPherson host type and infection type classification system were used to categorize patients in both the DAIR and 2-DAIR groups. Regression analysis was performed to control postoperative vs acute hematogenous infection, procedure, and comorbidities. The McPherson host types and infection types were not different between DAIR and 2-DAIR patients, P = .728 and P = .061, respectively.RESULTS:
There was no difference in the overall implant retention rate between DAIR and 2-DAIR (63.49% vs 69.23%, P = .605). The average days to reinfection was significantly longer for the 2-DAIR cohort compared with DAIR (271.3 vs 165.3, P = .024) in patients who failed treatment. However, when controlling for infection, microorganism, index procedure, and comorbidities, there was no difference in days to reinfection (P = .679). There were no differences in complications, 90-day readmission, or revision rates between the groups.CONCLUSIONS:
A staged debridement for acute prosthetic joint infection did not improve the rates of infection control. Randomized trials are needed to define indications and potential benefits of 2-DAIR.Palabras clave
