We report prosthetic knee arthritis in a 55-year-old diabetic man due to Granulicatella adiacens, a micro-organism present in the oral flora, usually described in endocarditis but rarely in prosthesis joint infection. This patient had undergone a dental extraction without antibiotic prophylaxis one month before, and an aseptic loosening of the prosthesis had been diagnosed previously. If antimicrobial prophylaxis against infective endocarditis for dental procedures is well established, such an approach is still controversial for joint prosthesis and should be considered in some conditions.
我们报告了一例 55 岁糖尿病男性因口腔菌群中的颗粒链菌（Granulicatella adiacens）引起的人工膝关节关节炎，这种微生物通常与心内膜炎有关，但很少与假体关节感染有关。该患者在一个月前进行了一次未经抗生素预防的牙科拔牙手术，此前曾诊断出假体关节无菌性松动。如果针对牙科手术的感染性心内膜炎的抗菌预防已经得到很好的确立，那么这种方法对于关节假体仍然存在争议，并且应该在某些情况下进行考虑。
