About this study

Official title: Adductor Canal Block and Functional Recovery After Total Knee Arthroplasty. A Double-Blind, Randomized Controlled Trial

This study aims to compare the functional recovery of patients undergoing Total Knee Arthroplasty based on the administration of an adductor canal block during their anesthesia treatment

Read the detailed description

The period after total knee replacement (TKR) surgery is known to be painful for the first 24 hours, lasting up to 3 days in many cases. Successful management of pain after TKR is regarded as necessary to early recovery, rehabilitation and timely discharge. Severe pain following major joint arthroplasty can hinder early rehabilitation, may result in prolonged hospitalization and is a strong predictor of persistent pain beyond 3 months. Adequate analgesia following TKR is paramount to early recovery, rehabilitation and timely discharge. Therefore early postoperative analgesic and rehabilitation goals are intricately related.

Until now, different methods of pain treatment have been used, including intravenous narcotic pain medication, continuous femoral nerve block (numbing medication to a nerve in the thigh) and epidural analgesia (identical to the numbing method for childbirth). These are all effective methods but each is limited by side effects. In recent years, research has focused on administering local anesthetic further down in the leg, trying to minimize quadriceps muscle weakness while giving adequate pain relief after surgery. Local Infiltration Analgesia (LIA) and Adductor Canal Block (ACB) are examples of new farther sites of administration.

The purpose of this study is to determine which combination of analgesic interventions is the most effective treatment for pain and improvement in functional outcome for TKR.

What is being measured

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

  1. Timed Up and Go test

    TUG test reflects the time it takes a subject to stand up from a standard height armchair, walk 3 meters, walk back to the chair and sit down. It intends to assess a patient's global mobility as well as balance and risk of falling.

    Measured: 2-3 days post srugery

Secondary outcomes (10)
  1. Pain outcome - NRS

    1. Pain scores assessed with an 11 point verbal numeric rating scale (NRS) where 0 is "no pain" and 10 is "the worst pain imaginable", both at rest and during active physiotherapy (measured daily for 3 days post-operatively) .

    Measured: 2-3 days post surgery

  2. Analgesic outcomes - Cumulative systemic opioid consumption

    Cumulative systemic opioid consumption measured as oral morphine mg equivalents (daily for 3 days post-operatively).

    Measured: 2-3 days post surgery

  3. Analgesic outcomes - Proportion of patients who required "rescue" intravenous patient controlled analgesia

    Proportion of patients who required "rescue" intravenous patient controlled analgesia (iv PCA) anytime in the post-operative period.

    Measured: 2-3 days post surgery

  4. Analgesic outcomes - Incidence of opioid-related side effects

    Incidence of opioid-related side effects

    Measured: 2-3 days post surgery

  5. Secondary short-term physical and performance-based functional outcome measures - Proportion of patients achieving knee flexion range of motion (ROM) of 90 degrees

    Proportion of patients achieving knee flexion range of motion (ROM) of 90 degrees (measured daily for 3 days post-operatively)

    Measured: 2-3 days post surgery

  6. Secondary short-term physical and performance-based functional outcome measures - Distance walked

    Distance walked

    Measured: 2-3 days post surgery

  7. Secondary short-term physical and performance-based functional outcome measures - Hospital length of stay

    Hospital length of stay

    Measured: 2-3 days post surgery

  8. Secondary short-term physical and performance-based functional outcome measures - Discharge destination

    Discharge destination (home or rehabilitation facility)

    Measured: 2-3 days post surgery

  9. Medium-term self-reported functional outcome measures - WOMAC

    Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) measured at baseline and at 3 months post-operatively

    Measured: baseline and 2-3 days post surgery

  10. Medium-term self-reported functional outcome measures - LEFS

    Lower extremity functional scale (LEFS) measured at baseline and at 3 months post-operatively.

    Measured: baseline and 2-3 days post surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Adductor Canal Block, Adductor Canal Block with Morphine and Local Infiltration in people with Total Knee Arthroplasty, run by University Health Network, Toronto at 1 site in Canada.

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 5 inclusion and 6 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 24 Nov 2017. 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 Canada. 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 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?

Timed Up and Go test (time frame: 2-3 days post srugery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02411149, which also lists 4 linked publications.

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 24 Nov 2017.
