Scientists in China have developed a hydrogel that may be able to treat osteoarthritis and slow down disease progression. The hydrogel restores cartilage lubrication, preventing the progression of early osteoarthritis. It is comprised of tiny hollow spheres made of a biomaterial derived from natural protein and a synthetic polymer, the combination of which creates a favorable environment for cell growth and hydration. The treatment is able to precisely target small areas of inflammation. The hydrogel has shown promise in rat studies, outperforming traditional treatments in terms of reducing friction and improving joint lubrication.

Scientists at Northwestern University have invented a goo that could open the door to regenerating human knee cartilage. The goo mimics the chemical structure of cartilage. Animal subjects who had their joints treated with the biomaterial grew new cartilage within six months. If the goo works in humans, it could benefit people who need knee replacement surgeries, athletes who experience ACL tears, and people who suffer from degenerative diseases like arthritis.
