A shot that reverses osteoarthritis
University of Colorado Boulder researchers built two therapies in two years: an injectable that delivers an FDA-approved drug into a joint in sustained bursts, and a biomaterial repair kit that recruits the body's own cells to patch cartilage and bone defects. In animals the injection returned arthritic joints to a healthy state within four to eight weeks, and the patches produced what the team called full regeneration. The arc will run as these move from animal and human-cell testing toward people, aiming to fill the current gap between pain management and joint replacement.
