Breast cancer survivors have known risk factors that might influence the results of total hip arthroplasty (THA) or total knee arthroplasty (TKA). This study evaluated clinical outcomes of patients with breast cancer history after primary THA and TKA. Our total joint registry identified patients with breast cancer history undergoing primary THA (n = 423) and TKA (n = 540). Patients were matched 1:1 based upon age, sex, BMI, procedure (hip or knee), and surgical year to non-breast cancer controls. Mortality, implant survival, and complications were assessed via Kaplan-Meier methods. Clinical outcomes were evaluated via Harris Hip Scores (HHSs) or Knee Society Scores (KSSs). Mean follow-up was six years (2 to 15).Aims
Methods
To investigate whether chronic kidney disease (CKD) is associated with the risk of all-cause revision or revision due to a periprosthetic joint infection (PJI) after primary hip or knee arthroplasty. This retrospective cohort study comprised 18,979 consecutive hip and knee arthroplasties from a single high-volume academic hospital. At a median of 5.6 years (interquartile range (IQR) 3.5 to 8.1), all deaths and revisions were counted. To overcome the competing risk of death, competing risk analysis using the cumulative incidence function (CIF) was applied to analyze the association between different stages of CKD and revisions. Confounding factors such as diabetes and BMI were considered using either a stratified CIF or the Fine and Gray model.Aims
Methods
The purpose of this study was to compare the
diagnostic accuracy for the detection of infection between the culture of
fluid obtained by sonication (SFC) and the culture of peri-implant
tissues (PITC) in patients with early and delayed implant failure,
and those with unsuspected and suspected septic failure. It was
hypothesised that SFC increases the diagnostic accuracy for infection
in delayed, but not early, implant failure, and in unsuspected septic
failure. The diagnostic accuracy for infection of all consecutive
implants (hardware or prostheses) that were removed for failure was
compared between SFC and PITC. This prospective study included 317
patients with a mean age of 62.7 years (9 to 97). The sensitivity
for detection of infection using SFC was higher than using PITC
in an overall comparison (89.9% Sonication is mainly recommended when there is implant failure
with no clear signs of infection and in patients with delayed implant
failure. In early failure, SFC is not superior to PITC for the diagnosis
of infection and, therefore, is not recommended as a routine diagnostic
test in these patients. Cite this article:
