Overview
The late-stage forms of degenerative osteoarthritis (OA) are very debilitating and less affordable to therapy. The main objective is to identify early onset symptoms of hand OA patients through imaging techniques (such as ultrasound and MRI). Our primary endpoint is to specify patients with high risk of radiological profression (X-ray).
