Raven the Black Lab-mix is about 1-and-a-half years old. Unfortunately, she recently tore the cranial cruciate ligament of her right hind leg. Cranial cruciate ligament disease is caused by a number of factors, including genetics, breed, and obesity. A dog with cranial cruciate ligament disease is predisposed to a ruptured ligament. This type of injury is more commonly seen among larger breed dogs of one to two years of age.
When a cruciate ligament is partially or completely ruptured, the dog will experience lameness on the affected leg and may hold it off the ground. Some may also experience pain and swelling.
Treatment for a torn cruciate ligament requires surgery and there are several options from which to choose, depending on the dog’s individual situation and the veterinarian’s recommendation. Raven had TPLO (tibial plateau leveling osteotomy) surgery to repair her torn ligament. TPLO involves stabilizing the joint with plates and screws and often has a very positive prognosis.
