Light-activated hydrogel might one day repair degraded cartilage in arthritic joints
A collaborative chemistry and orthopedics team has developed a technique that, if verified in animal and human tests, might one day be a therapy for osteoarthritis.
In osteoarthritis, joint cartilage loses some of its glycosaminoglycans, highly charged polysaccharides that enable the tissue to retain water, giving it load-bearing capacity and an ability to resist compression and wear. The result is joint pain, for which no direct treatment is currently available.
Now, chemist and biomedical engineer . . .
