There are two cruciate ligaments.
The posterior cruciate ligament is responsible for the knee being able to lock into position when fully extended. It prevents forces pushing the tibia posterior to the femur.
The anterior cruciate ligament prevents movement in the opposite direction, i.e. gives a limit to how much we can flex our knee. It is most commonly injured.

How do the articulating bones of the elbow prevent hyper-extension of this joint?
The articulating bones of the elbow joint, including the humerus, radius, and ulna, have specific bony structures and ligaments that limit the range of movement to prevent hyperextension. The olecranon process of the ulna fits into the olecranon fossa of the humerus, creating a bony block to limit extension. Additionally, the ulnar collateral ligament on the inner side of the elbow provides stability and restricts excessive outward movement, helping to prevent hyperextension.
