In dogs, the most common knee injury is a rupture or tear of the cranial cruciate ligament. Humans have a similar anatomical structure to the dog's knee, but the ligaments are called the anterior and posterior cruciate ligaments.
Canine Cranial Cruciate Ligament Diagram. Finding the Rupture. The ruptured cruciate ligament is the most common knee injury of dogs; in fact, chances are that any dog with sudden rear leg lameness has a ruptured anterior cruciate ligament rather than something else.
With CrCLD, ligament rupture is a result of subtle, slow degeneration that has been taking place over a few months or even years rather than the result of acute (sudden) trauma to an otherwise healthy ligament (which is very rare). This difference between people and dogs explains two important features of canine CrCLD:
Cranial Cruciate Ligament rupture (CCL) is one of the most common orthopedic injuries in dogs. This injury, similar to a torn ACL in humans, can come on suddenly or can appear gradually over a longer period. The cranial cruciate ligament helps the stifle (knee) function as a hinge joint.
The CCL in dogs is analogous to the ACL (anterior cruciate ligament) in people. This ligament connects the femur, the bone in the thigh, to the tibia, or shin bone, in the dog’s hind leg. It is located in the “knee” joint (called the stifle in dogs) and prevents the tibia from sliding forward.
A ruptured cranial cruciate ligament (CCL, sometimes called ACL) is the most common cause of hind limb lameness in dogs. If your dog ruptures their CCL, you want him or her back to normal activity level as soon as possible. Our team at Midwest Veterinary Specialists wants to help by offering.
The CCL has 3 main functions: (1) prevent cranial displacement of the tibia in relation to the femur (cranial drawer sign) (2) prevent hyperextension of the knee, and (3) prevent internal rotation of the tibia. Why does the CCL rupture? Unlike human athletes, rupture of the CCL in dogs is rarely the result of a traumatic injury.
This “traumatic” rupture can happen in dogs but is quite rare. Most commonly, CCLD is caused by a combination of many factors, including aging of the ligament (degeneration), obesity, poor physical condition, conformation, and breed.
If your dog is limping or has recently been diagnosed with a cranial cruciate ligament injury, you may be wondering about the cause and the treatment options. Read on to learn all about cranial cruciate ligament disease and what it means for your dog.
Cranial Cruciate Ligament Rupture. While the cranial cruciate ligament can rupture as a result of trauma, this is unusual. ... (Ruptured Cranial Cruciate Ligaments in Dogs) X-rays are an essential part of the investigations to confirm the findings from the physical examination and eliminate other possible causes of knee pain.
