NCT00665548

  Purpose

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.

Condition Intervention
Osteoarthritis
Radiation: X-ray; magnetic resonance imaging

Further study details as provided by University of California, San Francisco:

Primary Outcome Measures:
  • Determine which joint components demonstrate the greatest changes between weight-bearing and non weight-bearing protocols. [ Time Frame: at time of scan ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • 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. [ Time Frame: at time of scan ] [ Designated as safety issue: No ]

Estimated Enrollment: 33

Groups/Cohorts Assigned Interventions
Normal Subjects
Female subjects scoring Kellgren & Lawrence grade 0.
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.

OA Subjects
Female subjects with Kellgren & Lawrence score of 2 or 3.
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.

  • Women at risk of pregnancy
  • Weight greater than 250 lbs
  • History of surgery in the study knee
  • History of other diseases involving the study knee joint including inflammatory joint diseases, crystalline disease, and infection of the study knee
