Cranial Cruciate Disease in Dogs
Rupture of the cranial cruciate ligament in the hind leg is the most common orthopaedic condition we see in dogs. Seen more commonly in larger breed dogs such as Labradors and Rottweilers, we also see this injury in dogs down to 5-10kg and even cats occasionally.
There are two cruciate ligaments in stifle (knee) joint and they form a cross and counteract forward and backward movement between the tibia and the femur. In most cases it is the cranial cruciate ligament that tears and this often results in a tear in the medial meniscus inside the joint as well. While a lot of the time the injury occurs when your pet is exercising , sometimes it can occur just jumping out of the car or going down steps.
