بررسی تاثیر شستشوی تعدیل شده در بروز عفونت مفصل زانو پس از آرتروپلاستی کامل زانو

Background and purpose: Despite its effectiveness as a therapeutic intervention, Total Knee Arthroplasty (TKA) is sometimes followed by joint infection as a serious postoperative complication. That is why this study aimed to investigate the effect of modified irrigation on the frequency of knee joint infection following TKA. Methods: In this descriptive, cross-sectional study, ۱۲۰۱ patients undergoing TKA in private medical centers in Ardabil were investigated. For the selection of the patients to be included in the study, census sampling method was used. The information about each of the patients including their age, sex, education level, underlying diseases with or without infection, the type of infection, and laboratory test results (including WBC, hemoglobin, ESR, creatinine, blood sugar, platelet count, urea, and PMN) was obtained via checking their medical records, asking their treating doctor, and getting information from the patients themselves. The obtained data were analyzed using SPSS Software. Findings: Out of the total number of patients, ۵۸۶ (۴۸.۸%) were female and ۶۱۵ (۵۱.۲%) were male. The mean age of the patients was ۶۴.۸±۶.۱ years. Acute or chronic deep infections were not observed in any of the patients following the surgery. In ۲ of the patients, late hematogenous infection in the respiratory and urinary systems was detected. Non-purulent wound drainage was observed to be released from the surgical site in ۱۱ patients. Also, lack of full closure of wound was observed in ۴ of the patients under investigation. Fistula, however, was not observed in any of the patients. Conclusion: As the result of using modified irrigation method after TKA, no occurrences of joint infection (acute or chronic) or fistula were observed. This method was only found to be associated with late hematogenous infection and other non-infectious complications such as non-purulent wound drainage and lack of full closure of wounds.
