A cruciate ligament is a large ligament right in the middle of the knee - one of a pair.
What do the cruciate ligaments do?
There are two cruciate ligaments (anterior and posterior) and they are very important structures, connecting the thighbone (femur) and the shinbone (tibia) and stabilising the joint from frontwards and backwards forces.
|The word 'cruciate' means 'crossed', referring to the fact that the two cruciate ligaments cross over one another in the centre of the joint.||Here the bones are distracted so that you can see the attachments of both anterior and posterior cruciate ligament.||Demonstrating how the anterior cruciate ligament is tense when the knee is extended, and lax when it is flexed. The posterior cruciate does the opposite.|
