Roughly 151 million people worldwide suffer from osteoarthritis, meaning that they experience chronic pain, reduced mobility and limited quality of life. Attempts to repair cartilage thus far have offered limited functionality and only temporary pain reduction. The usual course of action is therefore to replace the entire joint, rather than repair the damaged cartilage. A team of researchers from the EU and Australia is however working on a promising alternative in which 3D printing plays a key role.
