Brief Summary:
The objectives of this study are: to identify and develop techniques to minimize precision errors in magnetic resonance imaging (MRI) evaluation of knee cartilage, and to determine if results from newly-identified MRI techniques in measuring cartilage changes and structure can be reproduced.

Condition or disease Intervention/treatment
Osteoarthritis, Knee Other: Magnetic Resonance Imaging

Detailed Description:
The development of a disease modifying osteoarthritis drugs (DMOADs) is currently limited by the inability to detect and monitor early cartilage damage that would be amenable to treatment. There is growing interest within the pharmaceutical and research community to use Magnetic Resonance Imaging (MRI) to identify biochemical and structural changes in the cartilage extra cellular matrix that occur early in the disease process. Although these techniques have been validated in small studies at single sites, multi-center evaluation of accuracy and precision, needed to apply these techniques to clinical trials of DMOADs, has not been performed. To address this need, the primary objective for this protocol is to identify and develop techniques to minimize systematic errors that decrease precision of MRI evaluation of knee cartilage, and to assess the reproducibility of the newly identified MRI techniques in measuring the cartilage morphometry and structure. Successful completion of this project may establish a multi-center imaging network in Pennsylvania for MRI evaluation of potential disease modifying osteoarthritis drugs (DMOADs) therapy.

Group/Cohort Intervention/treatment
Control--Non-Osteoporotic Knee
Kellgren-Lawrence (KL) scale score of 0, Age: 18-35 years
 Other: Magnetic Resonance Imaging
Subjects will undergo 4 sequential MRI evaluations of the target knee within a 4 week period to calculate precision error (ICC) in determination of cartilage morphometry (cartilage volume, mean thickness, and surface area), cartilage collagen (regional cartilage T2), and cartilage proteoglycan (regional cartilage T1rho).
Other Names:
  • MRI
  • knee MRI
  • knee magnetic resonance imaging
Minimal Osteoarthritis, Knee
Kellgren-Lawrence (KL) scale score of 1 or 2, Age: Older than 18; no upper limit
 Other: Magnetic Resonance Imaging
Subjects will undergo 4 sequential MRI evaluations of the target knee within a 4 week period to calculate precision error (ICC) in determination of cartilage morphometry (cartilage volume, mean thickness, and surface area), cartilage collagen (regional cartilage T2), and cartilage proteoglycan (regional cartilage T1rho).
Other Names:
  • MRI
  • knee MRI
  • knee magnetic resonance imaging
Moderate Osteoarthritis, Knee
Kellgren-Lawrence (KL) scale score of 3, Age: Older than 18; no upper limit
 Other: Magnetic Resonance Imaging
Subjects will undergo 4 sequential MRI evaluations of the target knee within a 4 week period to calculate precision error (ICC) in determination of cartilage morphometry (cartilage volume, mean thickness, and surface area), cartilage collagen (regional cartilage T2), and cartilage proteoglycan (regional cartilage T1rho).

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
This multi-center trial comprises only facilities within Pennsylvania. Study participants for the normal cohorts will be recruited through print flyers. It is anticipated that the study participants with mild to moderate OA will be identified by the radiologists interpreting the knee x-rays.

  • Participant had no change of treatment occur within the last 6 months;
  • Participants have no plans of changing to a different treatment within the next 3 months;
  • Participant must provide a study-specific signed informed consent form.

Exclusion Criteria:

  • Patients with contraindication to 3T MRI: Claustrophobia, Implanted metal or medical device that is not approved for MRI scanning at 3T, pregnancy, inability to tolerate relative immobility for 1 hour;
  • Patients with prior knee surgery or trauma of the knee;
  • Patients with KL score of 4.
