Bioinks hybrid 3D-printed help repair knee cartilage
It is good news for people who have suffered joint damage due to sport or age.
The human knee is prone to injury and wear out as we age. This often leads to the need for surgery. Researchers have developed hybrid bioinks which can be used to print 3D structures that replace damaged cartilage.
The meniscus is a rubbery cartilage cushion that prevents the upper and lower legs from rubbing together. The meniscus is susceptible to injury from sports, but it can also wear down with age. If the damage is severe, the only option is to remove some of the meniscus.
Researchers at the Wake Forest Institute for Regenerative Medicine have demonstrated a new 3D bioprinting method that can create both cartilage and supporting structures. The team used the Integrated Tissue and Organ Printing System, which was used in previous studies to print complex tissue such as bone, muscle and even ears.
