Postoperative infection after anterior cruciate ligament reconstruction caused by Finegoldia magna: a case report / 中华骨科杂志

ABSTRACT

One case of knee infection after anterior cruciate ligament reconstruction caused by the gram-positive anaerobic bacterium Finegoldia magna was reported. The patient was admitted to hospital due to fever and knee joint swelling and pain after anterior cruciate ligament reconstruction. Through medical history, physical examination, imaging examination and next-generation sequencing, it was confirmed that the infection was caused by Finegoldia magna. Through literature review, 37 literatures on infectious diseases caused by Finegoldia magna was retrieved and analyzed, and the identification points of anaerobic bacteria, the application of second-generation sequencing technology and the treatment status of infection after anterior cruciate ligament reconstruction were reviewed. The incidence of infection after arthroscopic anterior cruciate ligament reconstruction is low, while anaerobic infection is even more rare and difficult to culture. The next-generation sequencing can be used to assist the diagnosis. On the basis of giving priority to the preservation of the reconstructed ligament, the combined use of arthroscopic debridement, irrigation and sensitive antibiotics is the main treatment method.
