CRP and infection: Although a single abnormality in inflammation parameters, such as the erythrocyte sedimentation rate (ESR) or the C-reactive protein (CRP) value, has been reported to increase the likelihood of both infection or reoperation following revision arthroplasty [13], an elevation of the CRP values could also be attributed to other causes like cardiovascular, gastrointestinal, urologic or respiratory problems or even unknown causes [14].
