Due to selective breeding, the tibial plateau slope has become sloped too far backwards so there is a constant stress on the Cranial cruciate ligament. Over time this leads to a degenerative rupture. When it ruptures, the joint becomes unstable which causes pain and can lead to chronic progressive arthritis in the stifle if untreated.
Diagnosis: History, palpation, observation and proper radiography is important in properly assessing the patient. The key in diagnosing a rupture of the cruciate ligament is the demonstration of an abnormal gait in the dog. Abnormal knee motion is typically observed and diagnosis of a rupture can be made by performing the drawer sign test. [7] [9]
The cranial cruciate ligament (CrCL) stabilizes the dog knee much like the anterior cruciate ligament (ACL) does in humans. There are several modalities currently being used in the treatment of cranial cruciate ligament (CrCL) deficiency, which is a common and costly problem in dogs and sometimes cats.
An anterior cruciate ligament injury occurs when the anterior cruciate ligament (ACL) is either stretched, partially torn, or completely torn. [1] The most common injury is a complete tear. [ 1 ] Symptoms include pain, an audible cracking sound during injury, instability of the knee, and joint swelling . [ 1 ]
Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). [2] As with any injury, an understanding of the anatomy and functional interactions of the posterolateral corner is important to diagnosing and treating the injury.
The triple tibial osteotomy is a surgical procedure used to treat dogs that have completely or partially ruptured the cranial cruciate ligament in one or both of their stifles. [1] The cranial cruciate ligament connects the femur with the tibia , which functions to stabilise the canine stifle joint from the forces put on it during exercise and ...
Injuries to the legs: joint injury; ruptured tendons; ligament injury; broken legs. Internal injuries, especially to the lungs [2] Studies done of cats that have fallen from two to 32 stories, and are still alive when brought to a veterinarian clinic, show that the overall survival rate is 90 percent of those treated.

The cranial cruciate also resists over-extension and inward rotation, and is the most commonly damaged stifle ligament in dogs. "Cushioning" of the joint is provided by two C-shaped pieces of cartilage called menisci which sit between the medial and lateral condyles of the distal femur and the tibial plateau.
