Research from National Health Insurance Service Ilsan Hospital Has Provided New Data on Arthroplasty (The Incidence Rate, Microbiological Etiology, and Results of Treatments of Prosthetic Joint Infection following Total Knee Arthroplasty): Surgery – Arthroplasty

2023 OCT 05 (NewsRx) -- By a News Reporter-Staff News Editor at NewsRx Medical Devices Daily -- Investigators publish new report on arthroplasty. According to news reporting out of Goyang, South Korea, by NewsRx editors, research stated, “Periprosthetic joint infection (PJI) remains among the most challenging and costly complications. PJI rates vary from 0.39% to 3.9% after total knee arthroplasty (TKA).”

Our news journalists obtained a quote from the research from National Health Insurance Service Ilsan Hospital: “This study aimed to identify the causative microorganisms involved and to report our experience of subsequent treatment of PJI following over 7000 TKAs performed over 19 years. A retrospective study was conducted on 4547 patients (7019 cases) from March 2000 to September 2019. The incidence rate of PJI was 0.5%. Gram-positive bacteria accounted for 88.8% (n = 16) of the 18 cases, and * * S. aureus* * was the most commonly isolated pathogen (n = 7, 38.8%). There were six cases of MSSA and one case of MRSA. * * Streptococcus* * species (n = 7, 38.8%) also showed the same pattern. The CoNS species (n = 2, 11.1%) and Gram-negative bacteria (n = 1, 5.5%) were also reported. * * Candida* * species were isolated from 1 patient (5.5%). Successful I&D and implant retention (DAIR procedures) was achieved at the final follow-up in 19 patients (82.6%). The incidence of causative microorganisms was different for each PJI onset type.”

According to the news reporters, the research concluded: “The overall infection rate of PJI was less than 1%. Although the success rate of DAIR procedures is lower than the two-stage exchange arthroplasty in this study, it is possible to achieve acceptable success rates if DAIR procedures are carefully selected considering the virulence of the microorganism, duration since symptom onset, and early-onset infection.”
