If you fall or sustain a blow to the chest, you can fracture or dislocate the costal cartilage that attaches your ribs to your breastbone. Learn about symptoms, treatment, and recovery.

Scientists say they've identified a new type of cartilage — one that was actually discovered in the 19th century, forgotten, rediscovered and then forgotten again.

Researchers at TU Wien have developed a new way to grow cartilage from stem cells and guide it into basically any shape required. The breakthrough could lead to better ways to patch up injuries.
