Research Article: Can Platelets/Mean Platelet Volume Accurately Diagnose Periprosthetic Joint Infection? Revealing Their Actual Diagnostic Efficacy

Date Published: 2023-11-08

Abstract:
Periprosthetic joint infection (PJI) is a severe complication that can occur after total joint replacement (TJR). It often leads to pain, limited mobility, loosening of the prosthesis, prolonged antibiotic treatment, hospitalization, and the most severe outcomes of amputation or death. Due to the aging population and the increasing demand for TJR, the incidence of PJI is also increasing, causing a huge economic burden and mortality rate. Early and accurate diagnosis of PJI is of great significance for its subsequent treatment and prognosis. However, there is currently no independent or simple diagnostic gold standard for diagnosing PJI, so it is very important to find an index that can help clinicians effectively diagnose PJI. Bacterial infection around the prosthesis can lead to an immune response characterized by the recruitment and activation of neutrophils, and the infection can also activate the prothrombin activation pathway by releasing some procoagulant substances (such as tissue factor, thromboxane A,) Or by affecting the function of vascular endothelial cells to promote the aggregation of platelets and coagulation factors to form thrombus at the site of infection, these mechanisms may lead to the activation of the coagulation system and related inflammatory responses. These changes can be reflected in changes in the body’s blood parameters, so some key indicators for effectively predicting and diagnosing PJI can be obtained in a timely and accurate manner by means of routine blood tests.
