About this study

Official title: Intraoperative Arthroscopic Near-infrared Fluorescence Imaging of the Vascular Perfusion of the Meniscus in Patients Treated With Meniscal Repair

This trial is an explorative single center, single-arm study to assess whether vascularization of the meniscus can be visualized intraoperatively using arthroscopic near-infrared (NIR) fluorescence using ICG during standard of care meniscal repair treatment.

Read the detailed description

The meniscal healing process is based on two fundamental principles: a solid primary fixation, and a well-functioning biological process of cicatrization, where the presence of vascularization is thought to play a major role. Intra-operative near infrared fluorescence angiography using Indocyanine Green (ICG) is a widely used method for operative assessment of vascularization. Fluorescence guided detection of the vascularity surrounding a meniscal tear could be of great value to predict meniscal healing after repair.

This pilot study will explore the technical feasibility of intraoperative near-infrared fluorescence angiography of the meniscus in patients undergoing arthroscopic meniscal repair. Technical challenges for NIR fluorescence arthroscopy are the visibility of the vascular perfusion in microvessels in the dense meniscus, motion artifacts encountered with arthroscopy and wash in of ICG using a fluid irrigation system.

The included patients will be subdivided in four equal subgroups in order to evaluate alteration of NIR fluorescence signal during arthroscopy in combination with a tourniquet and/or irrigation pump system.

What is being measured

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

  1. NIR fluorescence of the meniscus

    Detection of fluorescence in the meniscus (yes/no), determined intra-operatively during the arthroscopy procedure using NIR fluorescence imaging and ICG.

    Measured: Fluorescence imaging will be performed from 0-10 minutes after injection of ICG

Secondary outcomes (5)
  1. T start

    Time between injection of ICG and initial detection of the fluorescence signal in the meniscus (T start).

    Measured: Fluorescence imaging will be performed from 0-10 minutes after injection of ICG

  2. I max

    Maximum fluorescence intensity (Imax) in the meniscus. Fluorescence intensity will be measured in arbitrary units as a mean of three different region of interests.

    Measured: Fluorescence imaging will be performed from 0-10 minutes after injection of ICG

  3. T max

    Time to maximum intensity of the fluorescence signal

    Measured: 0-10 minutes

  4. Baseline and End fluorescence intensity

    Baseline fluorescence intensity of the meniscus and the end fluorescence intensity in the meniscus

    Measured: Fluorescence imaging will be performed from 0-10 minutes after injection of ICG

  5. The ration between the maximum fluorescence intensity in the meniscus and the background fluorecence intensity.

    The fluorescence intensity is measured in arbitrary units as a mean of three region of interests.

    Measured: Fluorescence imaging will be performed from 0-10 minutes after injection of ICG

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.

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?

What does the primary outcome measure?

NIR fluorescence of the meniscus (time frame: Fluorescence imaging will be performed from 0-10 minutes after injection of ICG). 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 NCT05420974, 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?
