About this study

Official title: Two-arm, Double-blind Randomized Study Comparing Exparel and Exparel Plus an Adductor Canal Block in Total Knee Arthroplasty

Patients will be randomized (like the flip of a coin) to receive Exparel and a nerve block, standard of care for this procedure, or Exparel alone for pain management after surgery. They will also be asked to complete questionnaires before surgery, during their stay at the hospital after surgery, then at 3 months, 6 months and 12 months after surgery to assess pain and/or function levels, as well as the amount of pain medicine patients have used after surgery. Patients' leg strength will be measured immediately after surgery and again at 3, 6 and 12 months after surgery.

Being tested
Liposomal bupivacaine, Ropivacaine, Epinephrine, Clonidine, Saline
Medical subject headings
Osteoarthritis, Knee

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Liposomal bupivacaine, Ropivacaine and Epinephrine in people with Knee Osteoarthritis, run by The Hawkins Foundation at 1 site in United States.

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 4 inclusion and 8 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The record says: withdrawn, as of the sponsor's last update on 14 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. Some participants in this study may receive a placebo. 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The study was withdrawn before enrolling participants, so there are no results.

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?

Pain as assessed by Visual Analog Scale (VAS) (time frame: 12 Months). 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 14 Jan 2016.
