3D printed tissues may keep athletes in action

Bioscientists are moving closer to 3D-printed artificial tissues to help heal bone and cartilage typically damaged in sports-related injuries to knees, ankles and elbows.

Scientists at Rice University and the University of Maryland reported their first success at engineering scaffolds that replicate the physical characteristics of osteochondral tissue – basically, hard bone beneath a compressible layer of cartilage that appears as the smooth surface on the ends of long bones.
