A 54-year-old immunocompetent man presented to the office with severe right knee pain and swelling 27 days after knee arthroscopy. Additional diagnostics identified a monomicrobial infection of the right knee joint by the bacterium Leclercia adecarboxylata, which was later confirmed by repeated aspiration of the joint and culture of the aspirated fluid.
This case report details a postoperative monomicrobial infection with L. adecarboxylata after a knee arthroscopy in an immunocompetent host. Although infection by this bacterium is rare, this case demonstrates the possibility of L. adecarboxylata infection in the knee joint after orthopaedic surgery.
一名 54 岁免疫功能正常的男性在膝关节镜检查后 27 天因严重右膝疼痛和肿胀就诊。进一步的诊断发现右膝关节呈单一致病菌感染，病原菌为阿克曼氏菌属的莱克氏醋酸杆菌，这一结果通过重复关节抽吸和抽吸液培养得到了证实。
本病例报告详细描述了免疫功能正常的宿主膝关节镜术后发生的莱克氏醋酸杆菌单一致病菌感染。尽管此类细菌感染较为罕见，但本病例提示了莱克氏醋酸杆菌在骨科手术后感染膝关节的可能性。
