About this trial

This study aims to improve how doctors diagnose infections in patients with broken bones around joint replacements. Currently, there are no clear guidelines to help determine when an infection is present, making treatment decisions difficult. By studying how often infections are found through lab tests and identifying factors that predict infection, the investigators hope to create better ways to diagnose and care for these patients.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Adult patients (>18 years old) with periprosthetic fractures around primary or revision hip or knee arthroplasty

Patients requiring operative management for these fractures (fixation or revision arthroplasty)

Patients presenting to the University of Chicago Medical Center during two (2) year period (October 2025 to October 2027)

Disqualifiers

Patients undergoing non-operative management for periprosthetic fractures

Any documented or reported history of past prosthetic joint infection of the involved joint

Sinus tract at the time of presentation at the involved joint

Trial population

This population would include all consenting patients older than 18 years who present to the University of Chicago Medical Center with periprosthetic hip or knee fractures and will require operative management of the fracture or infection.

Treatments tested in this trial

  • Not applicable- observational study

    Other intervention

    The investigators are only looking to see the rate of positivity of the cultures as well as what the organisms that are found in the cultures are.
