Table 1.
Basic characteristics of the group of patients reoperated due to PJI and controls (median; range).
Fig 1.
Flowchart showing the number of patients included and excluded as well as their distribution in the infected and non-infected groups.
THA = total hip arthroplasty, TKA = total knee arthroplasty, TJA = total joint arthroplasty, PJI = prosthetic joint infection, IL-6 = interleukin 6, MSIS = Musculoskeletal Infection Society.
Table 2.
Modes infection among the patients from the group of PJI.
Table 3.
Data for IL-6 and synovial analysis (median; range) for the group of patients reoperated due to PJI and controls.
Table 4.
List of the pathogens cultivated from the sites of prosthetic joint infection.
Fig 2.
The ROC plot of the serum IL-6 diagnostic test.
This ROC plot applies for both THA and TKA (a); THA (b); and TKA (c). ROC = receiver operating characteristic curve, THA = total hip arthroplasty, TKA = total knee arthroplasty, TJA = total joint arthroplasty.
Table 5.
Cross tabulation of the IL-6 test results by the distribution of the patients to the aseptic and infected groups according to the MSIS criteria.
Table 6.
Diagnostic characteristics of the serum IL-6 test in the patients with THA and/ or TKA.
Fig 3.
The ROC plot of the synovial IL-6 diagnostic test.
This ROC plot applies for both THA and TKA (a); THA (b); and TKA (c). ROC = receiver operating characteristic curve, THA = total hip arthroplasty, TKA = total knee arthroplasty, IL-6 = interleukin 6.
Table 7.
Diagnostic characteristics of serum IL-6 when combined with other tests in patients with THA and/or TKA under assumption that both the tests are positive.
