Serious disregard for infection control practices at a New Jersey outpatient clinic left dozens of patients with septic arthritis, many who required surgery to drain infected joints. Two staff physicians and 2 medical assistants had treated the patients for osteoarthritic knee pain with intra-articular injections of a glucocorticoid or a hyaluronic acid-based product.

Earlier this year the New Jersey Department of Health identified 41 cases of septic arthritis among 250 patients treated at the clinic during the first week of March. Cultures of their synovial fluid or knee tissue revealed the presence of at least 12 types of bacteria. The organisms included Streptococcus mitis, Streptococcus oralis, Abiotrophia defectiva, Staphylococcus aureus, Actinomyces odontolyticus, and others that commonly are found in oral flora.

新泽西州一家门诊诊所严重忽视了感染控制措施，导致数十名感染性关节炎的患者离开医院，其中许多人需要进行手术以引流感染的关节。两名工作医生和两名医疗助理通过关节内注射糖皮质激素或透明质酸产品治疗了骨关节炎性膝关节疼痛。

今年早些时候，新泽西州卫生署在三月的第一周在诊所接受治疗的250名患者中鉴定出41例感染性关节炎。滑液或膝盖组织的培养物表明存在至少12种细菌。生物体包括缓症链球菌，口腔链球菌，Abiotrophia defectiva，金黄色葡萄球菌，放线菌odontolyticus，和其他人通常在口腔菌群中发现。
