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.
