Dog ACL (Cruciate) Repair and Surgery in Kitchener

We see many dogs limping after playing at the local dog parks around Kitchener. Often, a torn ACL is the reason. This is one of the leading causes of back leg limping we treat at Kingsdale Animal Hospital. Let's look at what this injury means for your dog and how we fix it.

What is Cranial Cruciate Ligament Disease?

The ACL (CCL) acts like a stabilizing band inside your dog's knee joint. When it tears, the knee becomes unstable. This instability causes a lack of function, pain and leads to arthritis. Although the final tear is acute, most dogs do not tear this ligament suddenly. It slowly degenerates over time.

Because of this slow wear and tear, dogs with one torn CCL have a high chance of tearing the other one later. Genetics, weight, and breed play a big role as well.

TPLO

Tibial Plateau Levelling Osteotomy

TPLO is the most successful procedure we perform for large or highly active dogs. Instead of replacing the torn ligament, this surgery changes how the knee mechanically works.

We make a curved cut at the top of the shin bone, called the tibia. We then rotate that bone segment to level the joint angle. We secure the bone in its new position with a custom metal plate and screws.

Levelling the bone stops the shin from sliding forward when your dog puts weight on the leg. The knee becomes completely stable during walking without needing a cruciate ligament at all. Clinical studies show dogs return to walking and trotting normally within 6 to 12 months.

Best for: Large breed dogs and highly active dogs of any size

* A board-certified veterinary surgeon travels to our Kitchener hospital to perform TPLO procedures.

Alternative option

Lateral Suture

Extracapsular Repair

We typically consider lateral suture stabilization for dogs weighing under 25 kg. Weight is just one factor. Your dog's activity level is actually the most important detail. Calmer dogs do much better with this procedure than dogs with high energy.

In this surgery, we do not cut any bones. We place two heavy, strong synthetic sutures outside the knee joint. These thick sutures mimic the job of the torn CCL. It holds the knee tight while your dog's body builds up thick fibrous or scar tissue around the joint.

Once that scar tissue forms, it provides long-term stability. We tend to avoid this surgery for highly active dogs. A high-energy dog can easily stretch or break the suture before the stabilizing scar tissue has time to develop.

Best for: Dogs under 25 kg with a calm temperament

What to Expect During the Recovery Period

A complete recovery takes several months of careful management. How well you handle the recovery period directly affects your dog's long-term comfort.

🏠

Strict Rest

Your dog should be confined to a small area to stop them from running or jumping.

🧊

Cold Therapy

Applying ice packs or a cold compression unit to the knee reduces swelling right after surgery.

Common Questions About Dog ACL Surgery

How do I know if my dog has a torn ACL?
The most common sign is sudden limping or holding up a back leg, especially after playing or exercise. Some dogs will sit with the affected leg extended to the side. If your dog is limping for more than a day or two, it's worth getting it checked.
How much does dog ACL surgery cost in Kitchener?
The cost depends on which procedure your dog needs and their size. We provide a detailed estimate after examining your dog so there are no surprises. Call us at (519) 896-0532 to book a consultation.
How long does recovery take after ACL surgery?
Most dogs begin bearing weight on the leg within a few weeks. Full recovery, including a return to normal activity, typically takes 3 to 6 months depending on the procedure and your dog's size and activity level.
Can a dog's ACL heal without surgery?
Very small dogs (under 10 lbs) can sometimes manage with strict rest and anti-inflammatory medication. For most dogs, the joint continues to deteriorate without surgical stabilization, leading to chronic pain and arthritis.
Which surgery is better, TPLO or lateral suture?
It depends on your dog. TPLO is the gold standard for large or active dogs and has the highest long-term success rate. Lateral suture works well for smaller, calmer dogs. Your vet will recommend the best option after examining your dog.
Does pet insurance cover ACL surgery?
Many pet insurance plans cover ACL surgery as long as the policy was in place before the injury occurred. Check with your insurance provider for details on your specific plan.
