CCL Injuries
Cranial Cruciate Ligament injury is the most common cause of hind limb lameness in dogs.
About the CCL
The cranial cruciate ligament (CCL) in dogs, is the equivalent of the anterior cruciate ligament (ACL) in humans. Unlike humans, the most common cause of CCL injury in dogs is due to degeneration of the ligament over time. This may be due to age, obesity, genetics, breed, activity level, and bone conformation.
Clinical Signs
of CCL Injury
- Difficulty Getting Up
- Trouble Jumping Into The Car
- Decreased Activity Level
- Limping on The Affected Leg
- Hindlimb Stiffness
- Muscle Loss
- Decreased Range of Motion of the Knee
- A Popping Noise
- Swelling on the Inside of the Knee
- Unwillingness to Play
- Positive Sit Test
Tests & Diagnosis
Diagnosis is made based on physical exam findings by a veterinarian. Sedation may be needed for a complete assessment. Though the CCL is not visible on x-rays, radiographs confirm secondary changes and can help rule out other joint injuries. Radiographs are also necessary for osteotomy surgical repair planning (see TPLO surgery).
Nonsurgical Management
All aspects of conservative therapy are important tenants of care in pets with CCL injury. Each aspect of non-surgical methods are recommended for each pet with CCL injury whether or not surgery is performed.
The decision to pursue surgery is best decided by you and your veterinarian and should take in account patient size, activity, concurrent medical conditions and quality of life.
- Weight Management
- Exercise Modification
- Joint Supplements
- Pain Management
Treatment Options
Surgery is the treatment of choice to provide stability in the joint. Studies have shown that surgical repair for CCL injuries leads to full function in the leg faster than other conservative methods. The decision to pursue surgery is best decided by you and your veterinarian.
