The Center for Osteoarthritis Research is a major center for research into the causes and treatment of osteoarthritis. Researchers from Tufts MC's Division of Rheumatology have been national leaders in the development of guidelines for treatment of knee osteoarthritis, in developing innovative ways to measure and assess damage to the knee, and in evaluating methods to treat osteoarthritis.
We helped design, develop, and implement the Osteoarthritis Initiative, a large cohort study of people with and at risk for knee OA in order to better understand risk factors for this very common condition. Over 250 papers have been published using the data generated from this important study. The data is open to use by other researchers free of charge.
The Osteoarthritis Center currently receives funding for several projects that use data from the Osteoarthritis Initiative including:
Peri-articular Bone Density as a Biomarker for Early Knee Osteoarthritis: We are testing if a knee bone-density scan is a good biomarker for early knee osteoarthritis. If we are able to show this, it could help in the development of an effective disease-modifying treatment for this condition.
Constitutional and Metabolic Factors Associated with the Development of Hand Osteoarthritis: We are evaluating the roles of structural and metabolic characteristics in the development of radiographic, symptomatic, and erosive hand osteoarthritis.
Rapid Quantitative Composite MRI Measurement of Knee Osteoarthritis Structural Progression: This project is aimed at developing and validating a knee osteoarthritis severity outcome measure that can be used with knee magnetic resonance images.
Characterization of Rapidly Progressive Knee Osteoarthritis: We are testing if rapidly progressive knee osteoarthritis, a poorly understood kind of arthritis, can be related to or described by: (i) anatomical features associated with injuries and abnormal loading, (ii) biochemical factors, (iii) certain types of instigating pathology, and (iv) distinct pathological processes.
Development of A Semi-automated Knee OA Cartilage Damage Index: We are developing a rapid cartilage measuring method that can be used for studies of knee osteoarthritis like the Osteoarthritis Initiative to quickly and effectively measure the amount of cartilage in the compartments of the knee.
Our clinical trials, supported by the National Institutes of Health, have included evaluations of whether vitamin D supplementation affects the progression of knee osteoarthritis, and whether repeated steroid injections into the knee can help treat the disease. We also work with industry partners to help test new drugs for the treatment of OA and other diseases.
