In one Journal of Orthopedic Research study, scientists have used 3D printing to repair the bones of mini-pig joints, a breakthrough that could help treat osteoarthritis in humans.
Specifically, the researchers used 3D printing with a network of needles to generate articular cartilage and subchondral bone using constructs composed of mesenchymal stem cells derived from adipose tissue.
Printed constructs were implanted into osteochondral defects created in the knees of six mini-pigs. Computed tomography and magnetic resonance imaging tests revealed significant repair of defects 3 and 6 months after implantation.
