Weight-Bearing Magnetic Resonance Imaging (MRI) for Analysis of Knee Osteoarthritis (OA)
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:
- whether the different x-ray and MRI techniques will give the same or different information about the knee joint and
- 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.

설명
Inclusion Criteria:
- Female
- 40 years and older
- Subjects who are willing and able to comply with x-ray and MRI procedures
- Evidence of a personally signed and dated consent document
Additional inclusion for normal controls:
- Infrequent knee pain, aching, or stiffness during the past year or infrequent use of medication for treatment of knee pain during the past year
- No evidence of OA on either knee (i.e. K-L grade = 0 diagnosed by knee radiography)
Additional inclusion for OA patients:
- Pain, aching, or stiffness on most days of a month during the past year; or use of medication for treatment of knee pain on most days of a month during the past year
- Kellgren-Lawrence Grade 2 or 3 of the study knee obtained on a Standard knee radiograph (with either the same or less severe OA, or no OA in the contralateral knee)
Exclusion Criteria:
- Subject is unable to undergo MRI because of contraindication
- 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

Normal Subjects
Female subjects scoring Kellgren & Lawrence grade 0.
|
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.
