3D printing may help treat osteoarthritis

In a Journal of Orthopaedic Research study, scientists used 3D printing to repair bone in the joints of mini-pigs, an advance that may help to treat osteoarthritis in humans. Specifically, the investigators used 3D printing with a needle-array to generate articular cartilage and subchondral bone using constructs composed of mesenchymal stem cells derived from fat…
