Results showed routine joint aspiration may not predict residual infection prior to reimplantation in patients undergoing two-stage exchange for periprosthetic joint infection.
“We concluded that reimplantation is not guided necessarily from aspiration and aspiration does not have that much value in ensuring a high success rate after reimplantation,” Emanuele Chisari, MD, of Rothman Orthopaedic Institute at Thomas Jefferson University, told Healio about results presented at the Musculoskeletal Infection Society Annual Meeting.
Chisari and colleagues retrospectively reviewed data for patients with PJI who underwent two-stage exchange between 2000 and 2019.
“PJI cases were defined based on 2018 [International Consensus Meeting] ICM criteria,” Chisari said. “Success rate was our primary endpoint and that was defined based on 2019 MSIS criteria for success after treatment of PJI.”
Researchers categorized 500 patients into three groups: patients who had both serum and synovial markers prior to reimplantation, patients who had serum markers but a dry tap at the time of aspiration and patients who did not undergo aspiration.
“A minimum 1-year follow-up after reimplantation was followed, and what we saw was no difference in success rate among the three groups,” Chisari said.
