Official Title Weight-Bearing MRI for Analysis of Knee OA
Brief 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. 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.
Detailed Description Not Provided
Study Type Observational
Study Design Observational Model: Case-Control
Time Perspective: Cross-Sectional
Target Follow-Up Duration Not Provided
Biospecimen Not Provided
Sampling Method Non-Probability Sample
Study Population Female, 40 years and older, community sample
Condition Osteoarthritis
Intervention Radiation: X-ray; magnetic resonance imaging

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/Cohorts
  • Normal Subjects
    Female subjects scoring Kellgren & Lawrence grade 0.
    Intervention: Radiation: X-ray; magnetic resonance imaging
  • OA Subjects
    Female subjects with Kellgren & Lawrence score of 2 or 3.
    Intervention: Radiation: X-ray; magnetic resonance imaging
Publications * Not Provided

*   Includes publications given by the data provider as well as publications identified by ClinicalTrials.gov Identifier (NCT Number) in Medline.
