About this study

The purpose of this study is to use better magnetic resonance imaging (MRI) techniques to examine the knee and the bony and soft tissue changes so as to better predict the progression of osteoarthritis and acute knee injuries.

Read the detailed description

The study will examine the pathophysiology of bone marrow changes, relationship between trabecular bone and cartilage changes; and evaluate T1p relaxation methods and its' relating to cartilage loss. The protocol is geared towards sequences utilizing 3 Tesla magnetic resonance imaging (MRI) that will enable the measures of cartilage volume and T2. Measures cartilage volume and T2 are more established MR methods for studying osteoarthritis (OA).

All OA and Anterior cruciate ligament (ACL) subjects will undergo MR imaging of the knee joint at 3 Tesla at baseline,, and three annual follow up time points. Regions of interest will include the total tibial and femoral cartilage, and sub-division such as the medial and lateral compartments of the tibial and femoral cartilage to account for localized disease activity and progression.

Bone marrow edema size, MR spectroscopy based marrow fat/water content, and trabecular bone microarchitecture underlying the edema will be measured in the OA and ACL groups to determine whether there is any distinction between these measures in OA and in traumatic ACL injury, cross-sectionally and longitudinally, and their relation to cartilage loss and OA progression.

Questions about this trial

What is this clinical trial studying?

An observational study of Osteoarthritis, Knee, 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 6 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 12 Dec 2013. 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?

Pathophysiology of bone marrow changes, relationship between trabecular bone and cartilage changes (time frame: Baseline, 1 year, 2 year, 3 year). 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 12 Dec 2013.
