About this study

Official title: Profiling of Abnormal Knee Joint Loading to Reduce Risk of Post-Traumatic Knee Osteoarthritis Following Anterior Cruciate Ligament Reconstruction

The purpose of this trial is to define knee joint pathomechanics (KJPM) in the first 2 years after ACL reconstruction (ACLR) and relate these KJPM with changes in articular cartilage morphology and quality.

Read the detailed description

This research project is a longitudinal prospective study. The investigators aim to define the KJPM longitudinally in the first 2 years following ACLR. The investigators relate these KJPM, combined with the cumulative mechanical exposure, to changes in articular cartilage/joint surface morphology and quality. To investigate the loading pattern on the knee joint, daily activities like walking, running and climbing stairs will be performed by the participants.

The overall goal of this research project is to investigate whether KJPM are related with early cartilage degeneration. This is a first major step towards reducing the risk for post-ACLR onset of Post-Traumatic Knee Osteoarthritis (PTOA).

Two work packages (WP) can be separated, that each have a separate aim:

WP1: The first aim of this WP (WP1.A) is to profile longitudinal changes in knee contact forces (KCFs) and knee contact pressure (KCP) distribution of the articular cartilage in the first 2 years following ACLR. Second, in WP1.B, the investigators will identify multivariate proxies of KCFs (and KCP) to improve clinical translation (for example by facilitating the development of prognostic tools for verifying KJPM in real life).

WP2: the second aim is to establish the relationship between KJPM at different time points following ACLR and (changes in) articular cartilage morphology and quality (WP2.A). Furthermore, the investigators will compare the biomechanical profile of "fast PTOA progressors" with "fast non-traumatic early osteoarthritis progressors" (WP2.B).

What is being measured

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

  1. Knee contact forces (KCF) will be measured using a 3D motion analysis system

    The goal is to profile longitudinal changes in KCFs of the articular cartilage.

    Using a 3D motion analysis system (Vicon, Oxford Metrics, UK), marker trajectories, ground reaction forces (AMTI, MA, USA) and muscle activations (Wireless EMG Cometa, Italy) will be measured. Subsequently a musculoskeletal modelling workflow in OpenSim will be used to calculate Knee contact forces (KCF) of the articular cartilage.

    Measured: 2 years

  2. Knee contact pressures (KCP) will be measured using a 3D motion analysis system

    Using a 3D motion analysis system (Vicon, Oxford Metrics, UK), marker trajectories, ground reaction forces (AMTI, MA, USA) and muscle activations (Wireless EMG Cometa, Italy) will be measured. Subsequently a musculoskeletal modelling workflow in OpenSim will be used to calculate Knee contact pressures (KCP) of the articular cartilage.

    Measured: 2 years

  3. The patient-specific cartilage thickness distribution.

    The cartilage thickness will be measured using the semi-automatic segmentation from the high-resolution images (3D-FSE) of the tibiofemoral cartilage.

    Measured: 2 years

  4. The patient-specific tibiofemoral cartilage quality.

    The cartilage quality will be examined using compositional measures such as T1rho, T1p and T2 relaxation time.

    Measured: 2 years

Individual data sharing
Yes: The full pseudonymized dataset will be made available in RDR (KU Leuven tool) and will be shared upon written request after approval of the PI, for clearly defined research purposes. Pseudonymized data and documentation will be available on request in RDR. Data sharing can only happen when it is not for commercial use or it doesn't reveal the identity of the participants. Data will always be pseudonimized.

Questions about this trial

What is this clinical trial studying?

An observational study of Anterior Cruciate Ligament Injuries and Post-Traumatic Osteoarthritis of Knee, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.

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 10 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: status not confirmed, as of the sponsor's last update on 11 Jan 2024. 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 Belgium. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Sabine Verschueren, PhD (0032 16 32 90 70, sabine.verschueren@kuleuven.be), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Knee contact forces (KCF) will be measured using a 3D motion analysis system (time frame: 2 years). The study lists 4 primary outcomes in all. 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 11 Jan 2024.
