The cranial cruciate ligament is thought to be able to resist a force equivalent to four times the weight of the dog before it ruptures, but often the ligament is weakened by arthritis that is present in the joint.
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.
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 size of the anterior cruciate ligament is often the most reported difference. Studies look at the length, cross-sectional area, and volume of ACLs. Researchers use cadavers, and in vivo placement to study these factors, and most studies confirm that women have smaller anterior cruciate ligaments.
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.
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 ]
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.
[2] [13] More than a 2.7 mm increase between sides indicates a fibular collateral ligament tear, while greater than 4.0 mm indicates with a grade III posterolateral knee injury. [20] Posterior stress radiographs taken with the patient kneeling show the amount of posterior tibial translation in both knees and are helpful to diagnose PCL ...
