Key Takeaways

• Canine ACL tears can occur when the ligament connecting the thigh bone to the shin bone in a dog’s knee joint is stretched or torn.
• Breeds like Labrador Retrievers, Rottweilers, Bichon Frises, and Newfoundlands are more susceptible to ACL tears due to their size, weight, activity level, and genetic predisposition.
• Symptoms of canine ACL tears include limping, difficulty walking or bearing weight on the affected leg, swelling around the knee joint, and decreased activity level.
• Diagnostic tests such as physical examinations, manipulation tests, x – rays, advanced imaging (MRI or CT scans), and arthroscopy are used to diagnose ACL tears in dogs.
• Treatment options for canine ACL tears include surgical procedures like TPLO or TTA surgery and non-surgical options such as rest, rehabilitation exercises, weight management, and medications.

Understanding Canine ACL Tears

Canine ACL tears occur when the ligament connecting the thigh bone to the shin bone in a dog’s knee joint is stretched or completely torn.

What is a Torn ACL in Dogs?

A torn ACL in dogs, also known as a cranial cruciate ligament (CCL) tear, is an injury to the knee joint that disrupts your pet’s mobility. It occurs when the anterior cruciate ligament has significant damage or breakage within the dog’s knee, leading to partial or full joint instability.

This condition doesn’t discriminate and can affect any breed, age, or dog size but is particularly prevalent among larger breeds with specific genetic predispositions. Like human ACL injuries, these can significantly impede a dog’s ability to walk and play normally without necessary treatment and care.

Causes of Canine ACL Tears

Determining the root of canine ACL tears requires understanding a number of factors. Breeds predisposed to this injury, like Labradors and German Shepherds, often suffer from genetic issues related to knee joint stability.

The cranial cruciate ligament (CCL), equivalent to the human’s anterior cruciate ligament (ACL), can be overstressed with excessive activity or obesity.

Additionally, age plays a role in ACL tear susceptibility in dogs. As your furry friend ages, their ligaments weaken naturally, which increases injury risk. Some even have congenital deformities that can make an ACL tear more likely.

Also worth noting are environmental triggers such as slippery floors or sudden changes in direction during high-speed activities, which put great strain on the dog’s knee joint.

Breeds Most Susceptible to ACL Tears

While any dog can suffer an ACL tear, certain breeds are more prone to this injury due to their size, weight, activity level, and genetic predisposition. Here’s a look at a few of these breeds:

Breed	Reason
Labrador Retrievers	These dogs are highly active and often overweight, putting extra stress on their joints.
Rottweilers	This small breed often suffers ACL tears due to high activity levels and jumping behaviour.
Bichon Frises	This small breed often suffers ACL tears due to high activity levels and jumping behavior.
Newfoundlands	The size and weight of Newfoundlands make them prone to joint and ligament injuries, including ACL tears.

Recognizing the Symptoms of Canine ACL Tears

Canine ACL tears can be identified through various symptoms, including limping, difficulty walking or bearing weight on the affected leg, swelling around the knee joint, and a noticeable decrease in activity level.

Signs and Indicators of ACL Tears

ACL tears in dogs can cause significant pain and discomfort, making it crucial for dog owners to recognize the signs and indicators of this injury. Here are the key signs that may indicate an ACL tear in your canine companion:

1. Limping: One of the most common signs of an ACL tear is limping, particularly a sudden onset or worsening limp. You may notice your dog favouring one leg or holding it up altogether.
2. Lameness: If your dog is experiencing lameness, meaning they cannot put weight on the affected leg, it could be a sign of an ACL tear.
3. Swelling: Swelling around the knee joint can occur following an ACL tear. It may be subtle at first but can become more pronounced over time.
4. Difficulty with stairs or jumping: Dogs with torn ACLs often struggle with activities that require them to use their hind legs extensively, such as climbing stairs or jumping onto furniture.
5. Reluctance to bear weight: If your dog seems hesitant to put weight on their injured leg or avoids using it altogether, it could indicate an ACL tear.
6. Decreased activity level: Dogs with ACL tears may become less active or reluctant to engage in their usual physical activities due to pain and discomfort.
7. Noticeable pain response: Your dog may exhibit pain when you touch or manipulate their injured leg. They may yelp, whine, or pull away from you when you attempt to examine the area.
8. Joint instability: In some cases, you may notice that your dog’s knee joint appears unstable or unsafe when they try to walk or stand.

Diagnostic Tests for ACL Tears

Diagnosing a canine ACL tear requires a thorough examination and specialized diagnostic tests. Here are the crucial difficulties that veterinarians use to determine if your dog has an ACL tear:

1. Physical Examination: The veterinarian will assess your dog’s gait, range of motion, and joint stability. They will look for signs of lameness, pain, and swelling in the affected knee.
2. Manipulation Tests: The veterinarian may perform a cranial drawer test or tibial compression test to evaluate the stability of the knee joint. These tests involve applying pressure or manipulating the leg to detect abnormal ligament movement or laxity.
3. X-rays: X-rays can help identify any bone abnormalities or degenerative changes in the knee joint. While X-rays cannot directly visualize soft tissue injuries like ACL tears, they can rule out other possible causes of lameness.
4. Joint Aspiration: In some cases, the veterinarian may recommend a joint aspiration to collect synovial fluid from the affected knee for analysis. This can help rule out other joint diseases and infections.
5. Advanced Imaging: MRI (Magnetic Resonance Imaging) or CT (Computed Tomography) scans provide detailed images of soft tissues, including ligaments and tendons. These imaging techniques are more accurate in diagnosing ACL tears compared to X-rays.
6. Arthroscopy: Arthroscopy is a minimally invasive procedure that involves inserting a small camera into the knee joint through tiny incisions. It allows direct visualization of the ligaments and can confirm an ACL tear while evaluating other potential joint pathologies.

Treatment Options for Canine ACL Tears

When treating canine ACL tears, there are two main options: surgical and non-surgical.

Surgical Options for ACL Tears

When it comes to treating ACL tears in dogs, surgery is often the recommended course of action. Here are the surgical options available for dogs with ACL tears:

1. Tibial Plateau Leveling Osteotomy (TPLO): TPLO is a common surgical procedure involving reshaping the tibia bone to change the knee joint’s angle. This reduces stress on the torn ligament and stabilizes the knee.
2. Tibial Tuberosity Advancement (TTA): TTA is another surgical technique that alters the dynamics of the knee joint, similar to TPLO. It involves cutting and repositioning the tibial tuberosity to correct ACL instability.
3. Extracapsular Repair: This surgical option involves replacing or reinforcing the torn ligament with a synthetic material outside the knee joint capsule. This provides stability and facilitates healing.
4. Tightrope Technique: The tightrope technique uses a strong suture material to create stability between bones in the knee joint, mimicking the function of the injured ligament.
5. Lateral Suture Technique: The traditional or “fishing line” technique entails placing a non-absorbable suture around specific structures within the knee joint to stabilize it.
6. Arthroscopy-Assisted Techniques: Arthroscopy is a minimally invasive surgical approach for diagnosing and treating various orthopedic conditions, including ACL tears in dogs. Surgeons can use arthroscopy to inspect and clean up debris within the joint during ACL repair surgeries.
7. Combination Procedures: In some cases, multiple surgical techniques may be combined to achieve optimal results based on an individual dog’s needs and condition.

Non-Surgical Treatment for ACL Tears

Non-surgical treatment options are available for dogs with ACL tears and can be effective in certain cases. These treatments focus on managing the symptoms and promoting healing without invasive procedures. Here are some non-surgical treatment options for canine ACL tears:

1. Rest: Rest is crucial for allowing the injured ligament to heal. Restricted activity and limited exercise help reduce stress on the knee joint, allowing it to recover.
2. Rehabilitation exercises: Controlled exercise and physical therapy can help improve strength and stability in the affected leg. This includes specific exercises that target muscle groups surrounding the knee joint.
3. Weight management: Maintaining a healthy weight is essential to alleviate strain on the knee joint. Extra weight puts additional pressure on the ligaments and can hinder healing.
4. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed by a veterinarian to manage pain and inflammation associated with ACL tears. These medications can help improve comfort during recovery.
5. Assistive devices: Using braces or orthopedic supports can provide additional stability to the affected leg, reducing strain on the injured ligament.
6. Physical therapy modalities: Techniques such as cold therapy (cryotherapy), heat therapy, ultrasound, laser therapy, and electrical stimulation may help reduce pain, decrease swelling, and promote healing.
7. Alternative therapies: Some dog owners opt for complementary treatments like acupuncture or chiropractic care to manage pain and support overall wellness during recovery.

Rehabilitation and Recovery

After a canine ACL tear, rehabilitation and recovery are crucial for your furry friend’s overall well-being. The goal of rehabilitation is to restore strength and function to the injured knee joint, allowing your dog to regain mobility and enjoy an active lifestyle.

Rehabilitation typically starts with controlled exercises and gentle range-of-motion activities, gradually progressing to more challenging movements as your dog’s condition improves. Physical therapy techniques such as hydrotherapy (water-based exercises), therapeutic ultrasound, and laser therapy may accelerate healing and reduce inflammation.

Alongside exercise, pain management plays a vital role in the recovery process. Your veterinarian may prescribe pain medications or recommend non-pharmaceutical alternatives like cold compresses or heat therapy to alleviate discomfort.

In addition to professional treatment, consistency at home is key. Following your vet’s guidance regarding activity restrictions, medication administration, warm-ups before exercise sessions, and other home care instructions will greatly aid in your dog’s successful recovery.
