Diagnosis of Deep Periprosthetic Infection of the Hip

Abstract

Periprosthetic infection (PJI) is one of the most frequent and devastating complications of total hip arthroplasty (THA). Early and accurate diagnosis of PJI allows timely initiation of treatment. Various diagnostic tools and algorithms for hip PJI diagnosis are described. The available serum (ESR, CRP, D-dimer, etc.) and synovial (alpha-defensin, leukocyte esterase, D-lactate) biomarkers are listed, as well as their combinations for the purpose of PJI verification. Combined serum and synovial tests can significantly improve the efficiency of PJI hip diagnosis.
