Biospecimen Retention: Samples Without DNA

Synovial fluid and tissue blood serum muscle biopsy

Estimated Enrollment:	88
Study Start Date:	April 2001
Study Completion Date:	May 2009
Primary Completion Date:	May 2009 (Final data collection date for primary outcome measure)

Groups/Cohorts
1 Participants with symptomatic knee osteoarthritis
2 Participants without symptomatic knee osteoarthritis, age-matched as controls

Detailed Description:

Through this study, we hope to learn about the natural history of knee osteoarthritis and the disability that arises from it. We hope to better understand why people with knee osteoarthritis develop difficulty with mobility (e.g. walking, standing) in hopes of finding a cure.

This study requires 1 four-hour visit to Harbor Hospital. The visit involves a physical exam, a DEXA bone density scan, blood and urine testing, knee x-rays, strength testing and a surface electromyography (EMG). Samples of muscle, joint fluid and joint tissue will be collected during your planned surgery.

Participation in this study is entirely voluntary.
