Brief Summary:
The primary objective of this study is to assess the diagnostic efficacy of the quantitative electrochemical LE biosensor for periprosthetic joint infection (PJI). The secondary objective of this study is to assess the utility of d-lactase as adjunct biomarker to LE in making a diagnosis of PJI.

Group/Cohort Intervention/treatment
Subjects undergoing revision joint surgery Diagnostic Test: leukocyte esterase electrochemical assay
A sample of blood drawn for routine standard of care laboratory assessments will be used to also test the new electrochemical assay. This is a validation study and the results of the electrochemical assay will not be used to treat patients

Primary Outcome Measures :
  1. Receiver Operating Curve (ROC) analysis [ Time Frame: 20 minutes ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
This will be a prospective study with consecutive revision joint surgery patients determined to be in one of three groups: 1) patients undergoing revision joint replacement for presumed aseptic loosening, 2) patients undergoing irrigation and debridement with implant retention, and 3) patients undergoing two stage revision for infection. We will also recruit a small number of patients undergoing primary joint replacement (Jefferson hospital only).

Inclusion Criteria:

1: consecutive patients undergoing at least one of the following procedures: presumed aseptic revision arthroplasty, irrigation and debridement, radical resection for periprosthetic joint infection

Exclusion Criteria:

  1. known active gout flare
  2. existing corrosion or metallosis
  3. inflammatory arthritis
  4. preexisting diagnosis of infection in the same joint
  5. patients undergoing second-stage procedure for infection.
