About this study

Official title: Tranexamic Acid in Revision Total Joint Arthroplasty: A Prospective Randomized Controlled Trial

To determine the optimal dosing regimen and route of administration of tranexamic acid (TXA) [single dose intravenous (IV), double dose intravenous, intravenous + topical, and oral repeated dosing] to minimize post-operative blood loss and transfusion requirements following revision total knee arthroplasty (RTKA).

Read the detailed description

Study Design: Prospective randomized control study

Scientific Background/Intro: Total hip or knee arthroplasty is associated with the risk of moderate to significant blood loss. Approximately one-third of patients undergoing total joint replacement surgery require one to three units of blood postoperatively. Tranexamic acid is a synthetic antifibrinolytic agent that has been successfully used orally, intravenously, and topically to control bleeding after total joint replacement. The use of TXA has been shown to significantly reduce the need for blood products during total joint replacement.1-3

Many studies have explored the use of various TXA regimens following primary TKA. Tanaka et al. demonstrated both that pre-operative administration of TXA was superior to intra-operative administration and that a double dose regimen is superior to a single dose regimen.4 Maniar et al. further supported the idea that pre-operative TXA administration is superior, and the addition of higher doses of TXA improved efficacy without an increase in thromboembolic complications.5 More recently, Lin et al. demonstrated that combining a pre-operative IV dose of TXA with an intra-articular dose after arthrotomy closure was superior to an intra-articular dose alone.6 Also, in an unpublished randomized control trial that we recently completed, we found oral TXA to provide equivalent blood control at a lower cost than IV TXA.

It is well known that revision joint arthroplasty cases are more complex than primary joint replacements. Revision total knee arthroplasty is associated with a greater risk of blood loss and increased transfusion rates compared to primary TKA.7 Despite the vast body of literature investigating TXA following primary TKA, only three retrospective studies have been published on the use of TXA after revision TKA.8-10 All three studies have shown that IV TXA decreased both the rate of transfusions and the amount of blood transfused when compared to controls.8-10

Although the TXA formulations used in primary TKA have been shown to be effective in the retrospective studies, the amount of blood loss and risk of transfusion still remains significantly higher than during primary TKA. By performing the first randomized control trial on the use of TXA following revision TKA, we believe it will help change practice patterns by providing evidence that the same TXA formulations used in primary TKA are inadequate for revision TKA. Additionally, we will be exploring new combinations of TXA administration to answer some questions brought up by previous studies in regards to the optimal TXA regimen.

What participants receive

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

  • Revision Total Knee Arthroplasty (TKA)Procedure or surgery

    Femoral component exchange, tibial component exchange, both component exchange, explant of both components and placement of antibiotic cement spacer, or a second stage re-implantation procedure. Given the variability in blood loss between types of revision TKA, randomization will be done to ensure equivalent numbers of each type of revision TKA between the treatment groups.

  • Revision Total Hip Arthroplasty (THA)Procedure or surgery

    Femoral component exchange, acetabulum component exchange, both component exchange, explant of both components and placement of antibiotic cement spacer, or a second stage re-implantation procedure. Given the variability in blood loss between types of revision THA, randomization will be done to ensure equivalent numbers of each type of revision THA between the treatment groups.

What is being measured

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

  1. Post-operative reduction in Hemoglobin

    Pre-operative hemoglobin minus the lowest post-operative hemoglobin prior to any transfusion

    Measured: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery

  2. Post-operative reduction in Hematocrit

    Pre-operative hematocrit minus the lowest post-operative hematocrit prior to any transfusion

    Measured: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery

  3. Calculated blood loss

    Based on predicted blood volume and hemoglobin balance

    Measured: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery

  4. Number of units transfused

    per patient

    Measured: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery

  5. Number of Patients Transfused

    Measured: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery

Secondary outcomes (4)
  1. Cost-comparison

    Cost differences resulted from differences in the blood transfusion rate, length of hospital stay, and management of complications as well as from the cost of the TXA itself

    Measured: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery

  2. Deep Vein Thrombosis, Pulmonary Embolus, Cerebrovascular accident or Transient ischemic attack

    Measured: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery

  3. Return to the OR within 30 days; Re-admission within 30 days; Periprosthetic fracture within 30 days

    Measured: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery

  4. Superficial infection or Deep infection, defined as Synovial White Blood Cell (WBC) count > 4200 WBC/ml or Synovial WBC > 3000 WBC/ml & C-Reactive Protein (CRP) > 10 mg/dl & Erythrocyte Sedimentation Rate (ESR) > 30 mm/hr ;

    Measured: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery

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 1 inclusion and 1 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: finished, as of the sponsor's last update on 22 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Post-operative reduction in Hemoglobin (time frame: Post-operative and before discharge from hospital (inpatient), < 30 days from surgery). The study lists 5 primary outcomes in all. 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 22 Apr 2021.
