About this study

Evaluation and comparison of histological analysis, 9,4 tesla MRI, Full-Field Optical Coherence Tomography (FFOCT) and ultrasound-based navigation system for cartilage degeneration analysis of patellofemoral joint.

Read the detailed description

Knee osteoarthritis (OA) is a common and debilitating chronic degenerative disease of the articular cartilage. Despite recent progress in the field of cartilage imaging, no routinely used clinical imaging modality has the ability to evaluate and monitor changes in cartilage degeneration. This observationnal, pilot, prospective, non randomized, uncontrolled, monocentric study aim to compare three of the most innovative imaging systems, namely the 9,4 Tesla MRI, the FFOCT (Full-Field Optical Coherence Tomography) and the ultrasound-based navigation system in order to image healthly to severely degraded human cartilage samples. All methods will be cross-correlated and compared with histological data considered as the gold standard.

Study groupRoleWhat they receive
Imaging measurementsAll subject of the study have a knee osteoarthritis (OA) and are going to have a knee prosthetic surgery with cartilage excision. Multimodal evaluation is conducted on ex vivo human cartilage samples (2 samples per patient are selected : healthy and severely degraded).

What is being measured

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

  1. Evaluation and comparison of histologic analysis, 9,4 Tesla MRI, FFOCT and ultrasound-based navigation system for cartilage lesions analysis of patellofemoral joint.

    Correlation between Osteoarthritis Research Society International (OARSI) grades performed for different modalities

    Measured: 6 months

Secondary outcomes (9)
  1. Evaluation of 9,4 Tesla MRI reconstructions in early osteoarthritis evaluation using visual qualitative information parameter obtained from the Average Pathlength Maps (APM).

    Correlation between MRI quantitative parameters and gold standard OARSI grade

    Measured: 6 months

  2. Evaluation of FFOCT reconstructions in early osteoarthritis evaluation using visual qualitative information parameter.

    Correlation between quantitative parameters from FFOCT and gold standard OARSI grade

    Measured: 6 months

  3. Evaluation of navigation ultrasound in early osteoarthritis evaluation using visual qualitative information parameter.

    Correlation between quantitative parameters from navigation ultrasound and gold standard OARSI grade

    Measured: 6 months

  4. Evaluation of of 9,4 Tesla MRI reconstruction in early osteoarthritis evaluation using visual quantitative information parameter obtained for the Average Pathlength Maps.

    Correlation between quantitative parameters from the Average Pathlength Maps and gold standard OARSI grade

    Measured: 6 months

  5. Evaluation of FFOCT reconstructions in early osteoarthritis evaluation using visual quantitative information parameter.

    Thickness average of cartilage

    Measured: 6 months

  6. Evaluation of FFOCT reconstructions in early osteoarthritis evaluation using visual quantitative information parameter.

    Roughness average of cartilage

    Measured: 6 months

  7. Evaluation of navigation ultrasound in early osteoarthritis evaluation using visual quantitative information parameter.

    Thickness average of cartilage

    Measured: 6 months

  8. Inter-observer robustness analysis of the OARSI classification

    Inter-observers Kappa coefficient

    Measured: 6 months

  9. Intra-observer robustness analysis of the OARSI classification

    Intra-observers Kappa coefficient

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Knee Osteoarthritis, run by University Hospital, Grenoble at 1 site in France.

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 2 inclusion and 1 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 11 Sep 2018. 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 France. 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?

Evaluation and comparison of histologic analysis, 9,4 Tesla MRI, FFOCT and ultrasound-based navigation system for cartilage lesions analysis of patellofemoral joint. (time frame: 6 months). 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 Sep 2018.
