The sternocostal joints, also known as sternochondral joints or costosternal articulations, are synovial plane joints of the costal cartilages of the true ribs with the sternum.{{Citation|last=Norris|first=Christopher M.|title=CHAPTER 14 - The thorax and thoracic spine|date=2011-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780702034732000186|work=Managing Sports Injuries (Fourth Edition)|pages=292–309|editor-last=Norris|editor-first=Christopher M.|place=Oxford|publisher=Churchill Livingstone|language=en|doi=10.1016/b978-0-7020-3473-2.00018-6|isbn=978-0-7020-3473-2|access-date=2020-11-23|url-access=subscription}} The only exception is the first rib, which has a synchondrosis joint since the cartilage is directly united with the sternum. The sternocostal joints are important for thoracic wall mobility.{{Citation|last1=Robicsek|first1=F.|title=SURGERY {{!}} Pectus Carinatum, Poland's Syndrome, Cleft Sternum, and Acquired Restrictive Thoracic Dystrophy|date=2006-01-01|url=http://www.sciencedirect.com/science/article/pii/B0123708796005238|encyclopedia=Encyclopedia of Respiratory Medicine|pages=159–171|editor-last=Laurent|editor-first=Geoffrey J.|place=Oxford|publisher=Academic Press|language=en|doi=10.1016/b0-12-370879-6/00523-8|isbn=978-0-12-370879-3|access-date=2020-11-23|last2=Fokin|first2=A.

The ligaments connecting them are:

• Articular capsules
• Intraarticular sternocostal ligament
• Radiate sternocostal ligaments
• Costoxiphoid ligaments
