Hipfl C, et al. - A total of 97 subjects were analyzed to study the microbiological findings on the spacer rods and the treatment outcome among chronically infected total knee arthroplasty (TKA) cases. Researchers recorded 3 reinfections caused by the same organism, 9 reinfections caused by a different organism, 9 cases requiring interim spacer exchange whereas 1 subject died in the early postoperative course. They found sonication cultures of the spacer rods positive in 2% of people with none of them failed. In candidates who sustained reinfection, they observed significantly worse host and limb status. Two individuals were given chronic antibiotic suppression whereas all patients had a TKA in place at the latest follow-up.
