Infection complicating 794 primary and revision arthroscopies. Accuracy of actual prophylactic procedures against infection and results from a single orthopedic center in Poland

Abstract Introduction Septic arthritis after arthroscopy (SAAA) is a devasting complication which reported frequency varies about 0.04%–5.7%. The aim of the study to analyze SAAA at one orthopedic center, risk factors and accuracy actual prophylactic measures. Materials Methods A retrospective (level evidence: V) includes 794 (665 primary 129 revision) “clean” arthroscopies performed in years 2017–2018 with confirmed joint infection during 30 days operation without use non-resorbable implants up 1 year procedures implants. Demographic medical data potential were analyzed: patients age, sex, operated joint, type procedure, or revision drains, usage non-absorbable implant, time surgery, BMI, lapse from index diagnosis SAAA, length hospital stay, causative microorganisms. All operations by eight different but experienced surgeons, theatre vertical laminar flow capacity 50 air exchanges per hour. perioperative antibiotic prophylaxis consisted preoperative dose g cefazolin simple arthroscopies, was prolonged 24 hours 3 doses cases implantation implant (55.8% patients). Results From 4 have been infected: 2 knee arthrolysis, ACL reconstruction rotator cuff repair. There early, manifestation within days, late-onset SAAA. Infections occurred 0.5% all 0.47% alone. Patients age surgery not found significantly infected non-infected cases, whereas non-revision cases. Conclusions Primarily aseptic arthroscopic respect preventive measures low postoperative septic arthritis. increases operation, significantly.
