The authors reviewed data on 122 DAIRs performed over a 16-year period. Overall, 67 percent of DAIRs were of primary arthroplasties, and 60 percent were performed within 6 weeks of the index arthroplasty. They found that infection eradication was achieved in 104 cases (85 percent) using a single or multiple DAIR approach, and 10-year implant survivorship was 77 percent. In 32 cases, more than one DAIR was required. "Early PJI and exchanging modular components at DAIR were independent factors for a four-fold increased infection eradication and improved long-term implant survival," the authors write. They also caution that DAIR is associated with increased morbidity, and a risk of further surgery and instability. Learn more...
