We reviewed 194 revision arthroplasties of the hip and knee performed over a ten-year period. The results of intraoperative Gram staining were available in 169 (87%). Thirty-two were found to be infected (11 hips and 21 knees) and 137 had no evidence of infection. Intraoperative Gram staining was negative in all 169 cases. The method therefore had a sensitivity of 0% for detecting infection. We conclude that the absence of organisms on intraoperative Gram staining during revision arthroplasty does not confirm the absence of infection.
我们回顾了在十年期间进行的194例髋膝关节翻修置换术。169例（87%）有术中革兰氏染色结果。发现32例感染（11例髋关节和21例膝关节），137例无感染迹象。169例术中革兰氏染色均为阴性。因此，该方法检测感染的灵敏度为0%。我们得出结论，翻修置换术中术中革兰氏染色未发现微生物并不能排除感染。
