Similar to our results, synovial fluid cultures have a low sensitivity for the diagnosis of TB-PJIs, and in most previous cases, patients were diagnosed based on periprosthetic tissue cultures.[9] In addition, the growth of TB in cultures often takes a few weeks, with an average of 23.7 days.[10] Results of laboratory tests can either be within normal reference ranges or show increased inflammatory indicators such as the ESR and CRP concentration. Here, CRP is linked to tuberculosis.
