Figure 2.

Timeline of the patient’s recalcitrant MRSA PJI of knee and hip. Red steps indicate continued infection, while green steps indicate resolution of infection as seen with no clinical symptoms and sterile deep tissue bacteriological cultures. The figure shows it was not until bacteriophage therapy was used that cure of infection occurred. IA refers to intraarticular administration. DAIR refers to debridement and implant retention surgery. MSIS refers to musculoskeletal infection society. The MSIS criteria for PJI diagnosis are well documented elsewhere [2].
