Trial summary

The purpose of the study is to use different x-ray and magnetic resonance (MR) imaging techniques to take pictures of the knee. There are two specific purposes to the study: 1. whether the different x-ray and MRI techniques will give the same or different information about the knee joint and 2. Read more about this study

About this study

Official title: Weight-Bearing MRI for Analysis of Knee OA

The purpose of the study is to use different x-ray and magnetic resonance (MR) imaging techniques to take pictures of the knee. There are two specific purposes to the study:

  1. whether the different x-ray and MRI techniques will give the same or different information about the knee joint and
  2. which part of the knee joint will show the biggest change using the different x-ray and MRI techniques. The study is not designed to test a hypothesis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • X-ray; magnetic resonance imagingRadiation

    Knee x-rays: acquired in both a standard or weight-bearing position and in non-weight-bearing position to measure joint space width and look at signs of osteoarthritis.

    3 Tesla MRI: magnetic resonance imaging of the study knee during weight-bearing conditions and traditional non-loaded condition all acquired with the same sequences.

Study groups in NCT00665548
Study groupRoleWhat they receive
Normal SubjectsFemale subjects scoring Kellgren \& Lawrence grade 0.
Receives: Radiation: X-ray; magnetic resonance imaging
OA SubjectsFemale subjects with Kellgren \& Lawrence score of 2 or 3.
Receives: Radiation: X-ray; magnetic resonance imaging

What is being measured

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

  1. Determine which joint components demonstrate the greatest changes between weight-bearing and non weight-bearing protocols.

    Measured: at time of scan

Secondary outcomes (1)
  1. Determine if additional information gained from weight-bearing images can explain the difference in joint space width (JSW) between weight-bearing x-ray and traditional non-weight bearing MRI.

    Measured: at time of scan

Questions about this trial

What is this clinical trial studying?

An observational study of Osteoarthritis, run by University of California, San Francisco at 1 site in United States.

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 5 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 17 Apr 2009. 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 United States. 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?

Determine which joint components demonstrate the greatest changes between weight-bearing and non weight-bearing protocols. (time frame: at time of scan). 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 17 Apr 2009.
