Further study details as provided by Department of Veterans Affairs:

Primary Outcome Measures:
  • Knee MR cartilage wear, Gait knee adduction moment, COMP value in blood. [ Time Frame: baseline or first and only visit. ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples Without DNA

One tube of blood identified with a unique number.

Enrollment: 177
Study Start Date: March 2009
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)

Detailed Description:

The tests will be done at the VA and Stanford and are not dangerous or painful. They are designed to help us learn more about the relationship of excess weight on cartilage degradation by testing a biomarker in blood. Gait testing involves walking in a lab that is about 20 meters long about 20 times. MR involves lying in a tube for less than 1 hour.
