About this study

Adductor canal catheters are being used to provide continuous postoperative analgesia after total knee arthroplasty surgery (TKA). There is much debate about where is the best position of continuous adductor canal block in patients undergoing TKA. Therefore, the investigators aim to compare the postoperative pain at three different level of continuous adductor canal block. Ninety six patients scheduled for total knee arthroplasty will be randomly divided into the three groups. In group 1, the adductor canal catheter is inserted at femoral triangle apex (the proximal end of the adductor canal). In group 2, the adductor canal catheter is inserted femur length/15*2 cm above the location where the nerve block performed in group 1. In group 3, the adductor canal catheter is inserted femur length/15cm below the location where the nerve block performed in group 1.

What is being measured

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

  1. Pain : Visual Analogue Scale (VAS) for pain

    The visual analog scale(VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" (0) and "worst pain." (10). The ends are defined as the extreme limits of the parameter to be measured(symptom,pain,health) orientated from the left(0, worst) to the right(10, best).

    Measured: Baseline (Before surgery)

  2. Pain : Visual Analogue Scale (VAS) for pain

    The visual analog scale(VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" (0) and "worst pain." (10). The ends are defined as the extreme limits of the parameter to be measured(symptom,pain,health) orientated from the left(0, worst) to the right(10, best).

    Measured: postoperative day 1

  3. Pain : Visual Analogue Scale (VAS) for pain

    The visual analog scale(VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" (0) and "worst pain." (10). The ends are defined as the extreme limits of the parameter to be measured(symptom,pain,health) orientated from the left(0, worst) to the right(10, best).

    Measured: postoperative day 2

Secondary outcomes (3)
  1. muscle strength

    Quadriceps strength of both legs was assessed by placing the dynamometer on the anterior of the ankle, between the malleoli.

    Measured: Baseline (Before surgery)

  2. muscle strength

    Quadriceps strength of both legs was assessed by placing the dynamometer on the anterior of the ankle, between the malleoli.

    Measured: postoperative day 1

  3. muscle strength

    Quadriceps strength of both legs was assessed by placing the dynamometer on the anterior of the ankle, between the malleoli.

    Measured: postoperative day 2

Questions about this trial

What is this clinical trial studying?

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 3 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 15 Oct 2021. 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 South Korea. 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.

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?

Pain : Visual Analogue Scale (VAS) for pain (time frame: Baseline (Before surgery)). The study lists 3 primary outcomes in all. 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 NCT04206150, which also lists 3 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 15 Oct 2021.
