The diagnostic accuracy of blood C-reactive protein and erythrocyte sedimentation rate in periprosthetic joint infections – A 10-year analysis of 1510 revision hip and knee arthroplasties from a single orthopaedic center

Our study indicates better sensitivity for CRP than ESR and similar specificity values for diagnosing chronic PJI. If results oscillate close to 10 mg/L for CRP and between 25 and 30 mm/h for ESR we propose to use different cut-off values depending on the demographic and/or clinical factors to increase diagnostic accuracy.
