In this article, our Fort Oglethorpe veterinarians discuss the topic of cruciate ligament ruptures in dogs and explain how TTA surgery can effectively address this injury.
Cruciate Ligament Ruptures in Dogs
The CCL, also known as the cranial cruciate ligament, is an important tissue in a dog's knee. It connects and stabilizes the upper leg to the lower leg by joining the femur and tibia. When the CCL gets torn, it can cause the dog to experience pain, immobility, and partial or complete joint instability. In dogs, a CCL rupture refers to a torn cranial cruciate ligament in the knee, which is similar to the ACL (anterior cruciate ligament) in humans.
Signs of a Cruciate Ligament Rupture in Dogs
When it comes to dogs and their cranial cruciate ligament tears, about 80% of cases are chronic onset ruptures caused by degeneration, which often happen as dogs age. This is commonly observed in dogs between the ages of five and seven.
On the other hand, acute onset ruptures are more frequently seen in four-year-old or younger puppies. These tears occur due to injuries that dogs may sustain while going about their daily activities and play.
Some symptoms that may indicate a cranial cruciate ligament rupture 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.
Treating a Cruciate Rupture With TTA Surgery
When a dog's cruciate ligament is torn, it affects the knee's stability, causing movement problems. The shin bone moves forward, making the dog feel like the knee won't stay in place, leading to limping.
TTA surgery alters the knee's shape, allowing the muscles to assist in stabilizing the knee during movement. This gives the dog a sense of stability, even though the ligament itself is still damaged.
However, it's important to note that there are risks associated with this major surgical procedure. It will only be recommended when it's the best option for your dog's cruciate injury.
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.
During your dog's recovery, it is essential to focus on pain management and rehabilitation therapy. Your dog's veterinarian will collaborate with you to establish a comprehensive care plan to ensure a successful healing process before the TTA surgery.
