cruciate ligament

1. The ligament of the ankle passing transversely across the dorsum of the foot that holds tendons of the anterior muscle group in place.
2. A cross-shaped ligament of the atlas consisting of the transverse ligament and superior and inferior bands, the former passing upward and attaching to the margin of the foramen magnum, the latter passing downward and attaching to the body of the atlas.
3. Either of two ligaments of the knee, the anterior (from the posterior femur to the anterior tibia), and the posterior (from the anterior femur to posterior tibia). They provide rotary stability for the knee and prevent displacement of the tibia. Synonym: cruciform ligament See: anterior cruciate ligament


A torn cruciate ligament causes instability and pain in the knee. The type of instability depends on which cruciate ligament is damaged.


Arthroscopic surgery is usually necessary to repair torn cruciate ligaments. Sometimes open surgery, or arthrotomy, is necessary for particularly complex repairs.
