Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patient is undergoing a revision total knee arthroplasty where in the opinion of the investigator, the patient's existing tibial component excludes the tibial tubercle as a valid intraosseous injection site.
  • Patient is able to understand the study design and intervention and gives informed consent to participate in the study.
  • Age > 18 years.

Who cannot join

  • Contraindication to receiving vancomycin, cefepime, ancef, or other standard of care pre-operative antibiotic (allergy, medical issue, etc).
  • Patient received or is scheduled to receive intravenous Vancomycin within 7 days prior to their planned revision procedure.
  • Any hardware, condition, or anatomic status that prevents the medial malleolus from being a viable intraosseous injection site.
  • Refusal to participate
  • Any condition, in the opinion of the primary investigator, that deems the participant unsuitable for participation in the research study.

About this study

Official title: Intraosseous (IO) Vancomycin Into the Medial Malleolus vs Intravenous (IV) Administration in Revision Total Knee Arthroplasty (TKA)

Purpose of this study is to compare the efficacy of intravenous and intraosseous antibiotic administration techniques during revision total knee arthroplasty

Being tested
Intraosseous Vancomycin

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Intraosseous VancomycinDrug

    IO vancomycin is administered via an intraosseous cannulation device (Arrow EZ-IO; Teleflex, Morrisville, NC) in the OR after sterile prep of the leg and draping has occurred prior to skin incision (500mg in approximately 100mL NS). Injection will take place into the medial malleolus (within a pre-specified region) immediately prior to incision.

Study groupRoleWhat they receive
Intraosseous (IO) VancomycinExperimentalIO vancomycin is administered via an intraosseous cannulation device (Arrow EZ-IO; Teleflex, Morrisville, NC) in the operating room after sterile preparation of the leg and draping has occurred prior to skin incision (500mg in approximately 100mL NS). Injection will take place into the medial malleolus (within a pre-specified region) immediately prior to incision.
Receives: Drug: Intraosseous Vancomycin
Intravenous (IV) VancomycinNo interventionPatients will receive the Houston Methodist Hospital orthopedic surgery standard of care pre-operative antibiotic regimen for revision total knee arthroplasty patients. This includes IV antibiotics (typically ancef or cefepime and vancomycin) will be started in the pre-operative period approximately 1 hour prior to incision (vancomycin dose weight based at approximately 15mg/kg [12,13] generally 1000-1750mg in 500mL NS).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Level of Vancomycin

    The study team will assess the level of vancomycin in the distal femur, proximal tibia, and systemic samples between the intravenous and intraosseous administration groups.

    Measured: During the surgery

Questions about this trial

What is this clinical trial studying?

A study testing Intraosseous Vancomycin in people with Revision Total Knee Arthroplasty, run by The Methodist Hospital Research Institute.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 20 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Level of Vancomycin (time frame: During the surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2026.
