About this study

Official title: Impact of Liposomal Bupivacaine Injected for Adductor Canal Block on Recovery Profile and Block Characteristics Following Total Knee Arthroplasty.

Study will evaluate the effect of liposomal bupivacaine versus standard bupivacaine on physical therapy measures and pain scores as well as opiate consumption.

Read the detailed description

Total knee arthroplasty (TKA) can be associated with a large amount of postoperative pain. This pain can oftentimes be severe enough to limit participation in physical therapy and ultimately delay discharge resulting in increased cost. Several strategies have been developed in an effort to decrease postoperative pain following TKA while maintaining lower extremity strength and maximizing participation in physical therapy. Recently, adductor canal blockade has gained popularity as it is reported to provide analgesia to the anterior knee without resulting in significant quadriceps muscle weakness. One downside of single shot peripheral blockade is the duration of analgesia can oftentimes be short lived. The advent of depot local anesthetics has made this an attractive option, especially in busy practices where placing peri-neural catheters may not be practical or cost effective. This study aims to carefully evaluate this relationship using a physical therapy evaluation method that relies on both motor strength and pain control. In addition, we hope to carefully evaluate motor strength using a novel method of strength measurement in an effort to further evaluate the impact of depot local anesthetic injection into the adductor canal on physical therapy and analgesia.

What participants receive

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

  • Peripheral Nerve BlockadeDrug

    Each study arm will receive their respective formulation of local anesthetic, either standard bupivacaine or liposomal bupivacaine upon randomization

  • 10 meter walk test on post-operative day 1Behavioural

    Patient asked to walk 10 meters at comfortable pace on post-operative day one when deemed safe to do so by the physical therapist

  • In person and over the phone questionnaireOther

    Presuming the patient has left the hospital each patient will be called on post-operative day 2, 3 to assess nausea, opioid consumption, satisfaction with anesthesia technique, nausea and vomiting as well as pain scores

  • Force transduction of quadriceps strengthDevice

    Patient will be asked to flex quadriceps at maximal ability and a transducer (Kiio device) will record a force value pre operatively and on post operative day 1

What is being measured

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

  1. 10 Meter Walk Test

    Time to comfortably walk 10 meters as deemed safe by physical therapy

    Measured: 24 hours

Secondary outcomes (4)
  1. Pain Scores

    Visual Analog Scores on a scale of 1-10, where 1 is pain free and 10 is the most pain.

    Measured: Day 0, Day 1, Day 2, Day 3

  2. Opioid Consumption in Morphine Equivalents

    Total opioid consumption will be measured in all patients over the course of 3 days and converted to oral morphine equivalents so that it can be statistically compared.

    Measured: Day 0 (OR), Day 0 (PACU), Day 1, Day 2, Day 3

  3. Number of Participants Who Experienced Nausea

    Post operative nausea and vomiting as documented in the PACU and volunteered in an over the phone interview

    Measured: Day 0, Day 1, Day 2, Day 3

  4. Quadriceps Strength

    Quadriceps Strength is measured in pounds of force using the kiio device, reported as the highest value of 3 collected.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Peripheral Nerve Blockade, 10 meter walk test on post-operative day 1 and In person and over the phone questionnaire in people with Pain, run by University of Wisconsin, Madison 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 6 inclusion and 12 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: stopped early, as of the sponsor's last update on 25 Jun 2019. 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. 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?

Yes. Results are posted in the registry (first posted 25 Jun 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

10 Meter Walk Test (time frame: 24 hours). 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 25 Jun 2019.
