Breakthrough U.S. Research Regrows Bone and Cartilage, Offering Hope for Arthritis Patients

Breakthrough U.S. Research Regrows Bone and Cartilage, Offering Hope for Arthritis Patients A U.S. federal health agency has funded radical scientific breakthroughs that successfully regrew bone and cartilage in animals, with one team regenerating an entire knee joint. The advances signal a potential future where damaged joints can be restored rather than replaced [122148]. The research, backed by the Advanced Research Projects Agency for Health (ARPA-H), targets osteoarthritis, a painful disease that breaks down protective tissue in joints. Scientists across three projects used different biological techniques to stimulate the body’s own repair mechanisms, moving beyond the current standard of artificial implants or pain management [122148]. These regenerative therapies have shown enough promise that human clinical trials are now being planned. If successful, they could transform care for millions of people suffering from arthritis, offering a more permanent biological solution [122148]. Lab-Grown Knees?
