Osteoarthritis Initiative (OAI): A Knee Health Study
This trial is active, not recruiting.
|Conditions||osteoarthritis, knee osteoarthritis|
|Sponsor||National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS)|
|Start date||February 2004|
|End date||October 2015|
|Trial size||5000 participants|
|Trial identifier||NCT00080171, NIAMS-109|
Knee osteoarthritis (OA) is the most common cause of disability in adults. The "Osteoarthritis Initiative (OAI): A Knee Health Study" is a nationwide research study that will help researchers gather more information about the physical changes that occur prior to the onset of arthritis symptoms or before OA gets worse. The purpose of this study is to examine people who have knee OA or are at high risk for knee OA; information will be used to better understand how to prevent and treat knee OA.

|Official title||Osteoarthritis Initiative (OAI): A Knee Health Study|
|Description||Knee OA causes more health problems and medical expenses that any other form of arthritis. Symptoms of OA can range from stiffness and mild pain to severe joint pain and even disability. Previous research has shown that certain factors, such as knee pain, prior knee injury or knee surgery, OA of the hand, or obesity, may lead to knee OA. The OAI is a multicenter, observational study of knee OA that will collect information on potential biomarkers for OA and trends in OA onset and progression. The OAI will recruit and follow participants who have knee OA or are at high risk for developing knee OA for an eight-year period at one of four clinical centers. Blood and urine collection, magnetic resonance imaging (MRI), and X-rays will be completed at each of four annual follow-up visits. A questionnaire and physical examination at screening will assess for risk factors for the development and progression of knee OA. Levels of knee pain and physical disability will be assessed at study start and at each of the follow-up visits by questionnaire and examination.|
