Irrigation and Debridement Modular Exchange and Implant Retention for Acute Periprosthetic Infection After Total Knee Arthroplasty

摘要

The role of irrigation and debridement, modular exchange, and implant retention for the treatment of periprosthetic joint infection (PJI) after total knee arthroplasty (TKA) remains controversial. The proposed benefits of debridement, antibiotics, and implant retention, often referred to as DAIR, include reduced economic cost and morbidity of 2-stage reimplantation . The primary disadvantage of this approach is a higher rate of failure and infection recurrence . Furthermore, several authors have demonstrated inferior outcomes of 2-stage exchange revision arthroplasty after a failed attempt at limited debridement with implant retention .
