Osteoarthritis, a common joint disorder affecting millions worldwide, has traditionally had no cure. However, new breakthroughs in regenerative medicine offer hope. Researchers at the University of Colorado Boulder, funded by a $33.5 million grant from ARPA-H, are working on an experimental treatment that could reverse osteoarthritis damage with a single injection. Instead of prosthetic joints or invasive surgeries, the approach harnesses the body's natural regenerative capabilities. The treatment involves an injection of an approved drug that helps stimulate the body's repair processes by targeting the affected joint. The injection uses a controlled particle system that slowly releases the drug, promoting tissue repair over several months. For more advanced osteoarthritis cases, a separate method uses biomaterials to create a scaffold within the joint, attracting cells to regenerate damaged cartilage and bone. Early animal studies have shown promising results, with joints returning to
