Monitoring of C-reactive protein level (CRP) and Erythrocyte sedimentation rate (ESR) after total hip and knee arthroplasty.

C-reactive protein (CRP) and Erythrocyte sedimentation rate (ESR) are the two most commonly serum biomarkers for the diagnosis of periprosthetic joint infections (PJI). We monitored CRP and ESR in 60 patients affected by osteoarthritis who underwent primary total hip or knee arthroplasty to verify their utility for an early diagnosis of periprosthetic hip and knee infections. In all but two patients, both CRP and ESR increased rapidly after surgery, reaching a peak value around the 3rd day postoperatively; CRP decreased rapidly in 20 days, reaching normal value one month after surgery, while ESR decreased slowly, reaching the normal value after three months. In two patients, CRP and ESR were still elevated six months after the surgical procedure and in both cases a diagnosis of PJI was made. Our study confirms that postoperative screening of CRP and ESR values are very useful in making an early diagnosis of this serious complication. Copyright 2020 Biolife Sas. www.biolifesas.org.
