If your dog suddenly starts limping or refuses to put weight on one of their hind legs, it could be a sign of a cranial cruciate ligament (CCL) injury. Similar to the ACL in humans, the CCL plays a crucial role in stabilizing a dog’s knee joint. At PetNest Animal Hospital, we frequently treat CCL injuries and want to help pet owners understand what they are, how they happen, and how your dog can heal.
What Is the CCL in Dogs?
The cranial cruciate ligament is a key stabilizing structure inside a dog’s stifle (knee) joint. It connects the femur (thigh bone) to the tibia (shin bone), preventing forward movement and rotation of the knee joint. When the CCL is torn or ruptured, it leads to joint instability, pain, and difficulty walking.
Why Do CCL Injuries Happen?
Ligament tears in humans often occur from sudden trauma. While this can also be true for canines, CCL injuries in dogs are also the result of gradual degeneration. Over time, the ligament weakens until it partially or fully tears. Common risk factors include:
- Age and Breed: Older dogs and certain breeds (like Retreivers, Rottweilers, and Bichon Frise) are most commonly affected.
- Excess Weight: Overweight dogs place more strain on their joints.
- High Activity Levels: Sudden turns, jumps, or slips can trigger a rupture.
- Genetics: Some dogs are predisposed to ligament weakening.
Signs Your Dog May Have a CCL Injury
Canines may have a ruptured cranial cruciate ligament if they are showing:
- Sudden lameness in one leg
- Difficulty rising or jumping
- Swelling around the knee
- Limping that worsens with activity
- Sitting with one leg stretched out to the side
If your dog shows these signs, contact your veterinarian. The vet will perform an orthopedic exam and may recommend X-rays to assess joint damage and rule out other causes.
How Dogs Recover from a CCL Injury
CCL injury treatment depends on the severity of the injury, your dog’s size and age, and their overall health. Options include:
Surgical Treatment (Recommended for Most Dogs)
CCL repair surgery is often the best way to restore stability and long-term function, especially in active dogs. There are a few different methods of surgical repair. Your canine’s surgeon will discuss the option that fits your pet’s specific injury.
Non-Surgical Management
If your canine has surgical risks, your veterinarian may suggest other methods to treat a CCL injury. The treatment plan may include a combination of pain and anti-inflammatory medications, weight management, joint supplements, and physical therapy
Rehabilitation and Recovery
Regardless of the treatment path, CCL recovery requires patience and commitment. Post-op or conservative care will likely involve controlled exercise and physical therapy. Your canine will require follow-up exams to monitor their progress over the course of weeks or even months.
