Due to the anatomy of a dog's leg, ACL injuries are very common for them. Today our Ventura vets explain the symptoms of ACL injuries in dogs as well as the surgeries that can be performed to treat these knee injuries.
ACL or CCL?
The anterior cruciate ligament is also known as the ACL. In people, it is a thin connective tissue in the middle of the knee.
This connective tissue in dogs is called the cranial cruciate ligament. Otherwise known as the CCL. It connects your pup's tibia to its femur. Although there are differences, the cranial cruciate ligament (CCL) is your dog's ACL.
One main difference between a person's ACL and your pup's CCL is that for dog's this ligament is always load bearing since your pet's knee is always bent when standing.
In dogs, CCL injuries tend to come on gradually, becoming progressively worse with activity until a tear occurs. ACL injuries in people are particularly common in athletes. These injuries tend to occur due to an acute trauma stemming from a sudden movement such as a jump or change of direction.
Signs of ACL Injuries in Dogs
The most common signs of a CCL injury in dogs are:
- Difficulty rising and jumping.
- Stiffness after rest or exercise.
- Hind leg lameness and limping.
Continued activity on a mildly injured leg will cause the injury to worsen and symptoms to become more pronounced.
Approximately 60% of dogs with a single CCL injury will go on to injure the other knee soon afterward. Dogs suffering from a single torn CCL will typically begin favoring the non-injured leg during activity which commonly leads to the injury of the second knee.
Treating Injuries of ACL in Dogs
When determining the best treatment for your dog's injury, your vet will take your dog's age, size and weight into consideration as well as your pup's lifestyle and energy level. If your pooch has been diagnosed with a cruciate injury, there are a number of treatment options available from knee braces to surgery.
Treatment Options
Knee Brace
Treating a CCL injury with a knee brace is a non-surgical option that may help to stabilize the knee joint in some dogs. The support provided by a knee brace gives the ligament time to scar over and repair itself. Treating CCL injuries through the use a knee brace may be successful in some dogs when combined with restricted activity.
Extracapsular Repair - Lateral Suture
This surgery involves replacing the torn cruciate ligament with an artificial ligament on the outside of the joint. This ACL surgery for dogs is typically recommended for small to medium sized breeds weighing less than 50lbs.
Tibial Plateau Leveling Osteotomy - TPLO
TPLO is a popular and very successful surgery that works to eliminate the need for the cranial cruciate ligament (CCL) by cutting and flattening the tibial plateau, then stabilizing it in a new position with a plate and screws.
Tibial Tuberosity Advancement - TTA
TTA surgery also eliminates the need for the CCL ligament by cutting the top of the tibia, moving it forward, and then stabilizing it in its new position with a stainless steel metal plate.
Recovery from ACL Surgery
Regardless of which treatment you decide is best for your dog, recovery from a dog ACL injury is a slow process. Expect your dog to require 16 weeks or longer to have complete healing and return to normal function. A year after surgery your dog will be running and jumping like their old self again.
To speed your pup's recovery from an ACL injury be sure to follow your vet's advice and never force your dog to do exercises if they resist. To avoid re-injury be sure to follow your vet's instructions closely and attend regular follow-up appointments so that your veterinarian can monitor your pet's recovery.
