TTA Surgery for Cruciate Ligament Ruptures in Dogs

Cruciate ligament ruptures are a common orthopedic injury in dogs that may require surgery to repair. Our vets discuss cruciate injuries in dogs and how surgeries like TTA (Tibial Tuberosity Advancement) can help them recover and feel good again.

Dogs & Cranial Cruciate Ligament (CCL) Ruptures

The CCL is a connective tissue in the knee that connects and stabilizes the lower leg to the upper leg. It joins a dog’s tibia to the femur above, and when torn, it results in partial or complete joint instability, pain, and immobility. CCL ruptures are the result of a torn cranial cruciate ligament (CCL) in a dog's stifle (knee), which is equivalent to the ACL in humans. 

What are the symptoms of a cruciate ligament rupture in dogs?

When it comes to torn cranial cruciate ligaments in dogs, 80% of cases are chronic-onset ruptures caused by degeneration, which usually occur due to aging. This is most commonly seen in dogs aged five to seven.

Acute onset ruptures are most commonly seen in dogs four years or younger. These tears are caused by injuries sustained while running around and living their daily lives.

Symptoms of a torn cranial cruciate ligament may include:

  • Crepitus (crackling noise of bones rubbing against each other)
  • Decreased range of motion
  • Hind leg extension while sitting
  • Pain when the joint is touched
  • Lack of motivation to exercise
  • Irritability
  • Restricted mobility
  • Stiffness after exercising
  • Swelling/Inflammation
  • Thick/firm feel of the joint
  • Weight shifted to one side of the body while standing
  • "Pop" sound when walking

If you notice any of the listed symptoms above, contact your vet and schedule an examination for your pup.

What is TTA surgery and how does it work?

When a dog experiences a cruciate ligament rupture, the knee loses the necessary stability to perform as expected. This instability causes the shin bone to move forward in such a way that your dog feels as though it will not lock in place, and your dog will most likely limp to avoid this.

When a dog undergoes TTA surgery, it changes the shape of the knee, allowing the muscles to help stabilize the knee while in use. Your dog will then feel as though the knee has been stabilized even though the ligament itself is still technically damaged.

There is a risk of complication with a surgical procedure of this magnitude, and as such, it will only be performed when it is the best option for the cruciate injury that your dog has sustained.

What is the cost of a TTA surgery for a dog?

The cost of TTA surgery for dogs can vary based on factors like the dog's size and the severity of the condition. Consulting with a veterinarian will provide an accurate estimate tailored to your dog's specific needs.

Recovery After TTA Surgery for Cruciate Injuries in Dogs

Dogs generally recover quickly from TTA surgery .

  • 24 Hours Post Op: Approximately 50% of dogs that have undergone this surgical procedure will be walking by this time.
  • At two weeks, Most dogs can bear moderate to complete amounts of weight on the leg.
  • By ten weeks, The majority of the dogs will no longer be walking with a limp.
  • At four months, Most dogs will be playing as usual, with the only limitations being high-stress activities.
  • Within six months: Most dogs will be back to enjoying most activities as they had been before injury and surgery.

Throughout recovery, pain management and rehabilitation therapy will be crucial to your dog's healing. Your dog's vet will work with you both to ensure that a complete recovery care plan is set in place prior to the TTA surgery.
