ESR and CRP are useful between stages of 2-stage revision for periprosthetic joint infection

چکیده
BACKGROUND Serum erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are important tests in the initial diagnosis of periprosthetic joint infection. Many surgeons also use these tests to determine if infection has resolved between stages of a 2-stage procedure, but little data exist regarding this practice. METHODS A retrospective review of our institutional total joint databases was conducted to determine sensitivity, specificity, and predictive values of elevated ESR and/or CRP to diagnose persistent infection between stages. RESULTS Among 16 knees and 5 hips, sensitivity was 50% for CRP, 75% for ESR, and 100% when combined. The negative predictive value of persistent infection was 100% when neither test was elevated. CONCLUSIONS Results of this study support the use of CRP and ESR as indicators of the resolution of periprosthetic joint infection between stages of 2-stage revision.

Purpose: To investigate whether surgery for PJI of the hip, the number of procedures and their duration contribute to risk of HO formation. Methods: 56 patients with hip PJI undergoing one-stage (10) or two-stage (46) exchange arthroplasty were matched to 112 patients undergoing revision arthroplasty for aseptic failure based on age, gender, body mass index (BMI), surgical approach (all direct...

متن کاملEfficacy of erythrocyte sedimentation rate and C-reactive protein level in determining periprosthetic hip infections.
The diagnosis of periprosthetic hip infections is often challenging. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level blood laboratory tests are commonly used to aid in the diagnosis. We studied the sensitivity, specificity, and false-negative rates of ESR and CRP level in a prospective group of patients who underwent revision total hip arthroplasty between 2000 and 2008....

BACKGROUND Diagnosis of a low-grade periprosthetic joint infection (PJI) prior to revision surgery can be challenging, despite paramount importance for further treatment. Arthroscopic biopsy of synovial and periprosthetic tissue with subsequent microbiological and histological examination can be beneficial but its specific diagnostic value has not been clearly defined. METHODS 20 consecutive ...
