TTA Surgery for Cruciate Ligament Rupture

Cruciate ligament ruptures are common orthopedic injuries in dogs that may require surgery to repair. Here, our Los Angeles vets discuss cruciate ligament ruptures in dogs, and how TTA surgery can repair the injury.

Cruciate Ligament Ruptures in Dogs

The CCL is a connective tissue that connects and stabilizes the lower leg to the upper leg in the knee. It connects the tibia to the femur above and, if torn, causes partial or complete joint instability, pain, and immobility.CCL ruptures are caused by a torn cranial cruciate ligament (CCL) in the stifle (knee) of a dog, which is equivalent to the ACL in humans.

Signs of a Cruciate Ligament Rupture in Dogs

When it comes to cranial cruciate ligament tears in dogs, 80% of cases are chronic onset ruptures caused by degeneration and usually occur as a result of aging. This is most common in dogs aged five to seven.

Acute onset ruptures are most commonly seen in pups four years or younger. These tears are caused by injuries a dog will sustain just running around living their daily lives.

Symptoms of a cranial cruciate ligament rupture 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.

TTA Surgery for Dogs

When a dog's cruciate ligament ruptures, the knee loses the necessary stability to perform normally. This instability causes the shin bone to move forward, giving your dog the impression that it will not lock in place, causing him to limp.

When a dog undergoes TTA surgery (Tibial Tuberosity Advancement) it changes the shape of the knee allowing the muscles to help with the stabilization of the knee itself 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.

If you're concerned about the cost of TTA surgery for dogs, speak with your vet directly. They should be able to provide you with an accurate estimate.

Recovery After TTA Surgery

Healing from TTA surgery is generally rapid.
  • 24 Hours Post Op: Approximately 50% of dogs that have undergone this surgical procedure will be walking by this time.
  • At 2 weeks: Most of the dogs will be able to bear moderate to complete amounts of weight on the leg.
  • By 10 weeks: The majority of the dogs will no longer be walking with a limp.
  • At 4 months: Most dogs will be playing as usual with the only limitations being high-stress activities.
  • Within 6 months: Most dogs will be back to enjoying most activities as they had been before injury and surgery.

Pain management and rehabilitation therapy are essential during the healing process for your dog. Your dog's veterinarian will collaborate with you both to make sure that your dog has a thorough recovery care plan in place before the TTA surgery.
