Biomaterial improves knee cartilage repair
from Johns Hopkins University via Laboratory Equipment
In a small study, researchers reported increased healthy tissue growth after surgical repair of damaged cartilage if they put a hydrogel scaffolding into the wound to support and nourish the healing process. The squishy hydrogel material was implanted in 15 patients during standard microfracture surgery, in which tiny holes are punched in a bone near the injured cartilage. The holes stimulate patients' own specialized stem cells to emerge from bone marrow and grow new cartilage atop the bone.
