These ligaments attach the femur (thigh bone) with the tibia (shinbone), the long bones to a higher place and below the knee articulation (which is known as the stifle joint in quadruped/four-footed animals).

4 chief ligaments agree the knee joint together and go along information technology stable:

Anterior medial and lateral collateral ligaments run down the inside and outside of the knee.

Causes

A cruciate ligament rupture can occur due to a traumatic outcome that results in a severe twisting or pivoting of the knee articulation or slow degeneration of the articulation due to age. When the ligament ruptures, the unabridged joint becomes unstable, and the leg bones tin easily motility out of place. Information technology is quite common for damage to occur to other parts of the joint, such every bit the meniscus at the same time as a cruciate rupture.

Ruptures may be partial or full (complete). A partial rupture means only one of the two cruciate ligaments has been torn. A full rupture occurs when both the cranial and posterior cruciate ligaments tear.

There is a higher incidence of cruciate ligament ruptures in cats who are overweight.

Symptoms

Cats with a ruptured cruciate ligament most normally present with rear limb lameness. The cat may also hold the affected limb off the ground. Symptoms tin be sudden onset if an injury or trauma is the cause or slowly progress over some time.
