Prosthethic Joint Infection (PJI) is a severe complication following joint replacement. Late PJI can occur years after implantation by hematogenous seeding of a microbial agent. is a coagulase-negative commensal of the human skin and rarely associated with opportunistic human infections. We report the rare case of a 70-year old Patient suffering from knee pain 18 years after primary Total Knee Arthroplasty. Microbiological sampling detected as causative agent. The patient was successfully treated with a two-stage implant exchange and antibiotic therapy using co-amoxicillin and rifampicin/cotrimoxazol. This case illustrates the ability of to cause late PJI and the importance of not letting coagulase-negative Staphylococci be routinely categorized as contaminants of microbiological samples.
人工关节感染（PJI）是关节置换术后的一种严重并发症。晚期PJI可在植入数年之后因微生物经血行播散而发生。[具体细菌名称未给出]是人类皮肤的一种凝固酶阴性共生菌，很少与人类机会性感染相关。我们报告了一例罕见病例，一名70岁患者在初次全膝关节置换术后18年出现膝关节疼痛。微生物学采样检测到[具体细菌名称未给出]为病原体。该患者通过两阶段植入物置换以及使用阿莫西林克拉维酸钾和利福平/复方新诺明进行抗生素治疗而成功治愈。该病例说明了[具体细菌名称未给出]导致晚期PJI的能力，以及不将凝固酶阴性葡萄球菌常规归类为微生物样本污染物的重要性。
