If your dog is suffering from a torn ACL (CCL) our Santa Cruz County vets may recommend TPLO surgery to repair the injury and help to return your dog to an active lifestyle.
Why is my vet recommending TPLO surgery for my dog?
TPLO or Tibial Plateau Leveling Osteotomy surgery is often recommended for dogs suffering from a torn cranial cruciate ligament (CCL).
What is the CCL?
The cranial cruciate ligament is the ligament that connects your dogs tibia (the bone below the knee) to their femur (the bone above their knee). In humans this ligament is known as the ACL or anterior cruciate ligament.
Unlike humans, because a dog's hind legs are always bent, the CCL is always a load bearing ligament. When the CCL is injured, your dog's knee becomes unstable and painful.
Symptoms of a CCL Injury
Symptoms of a CCL injury in dogs can appear suddenly but typically develop gradually. The most common signs of an CCL injury are:
- Stiffness (most noticeable after rest, following exercise).
- Difficulty rising and jumping.
- Hind leg lameness and limping.
Continued activity on a mildly injured CCL will cause the injury to worsen and symptoms to become more pronounced.
Approximately 60% of dogs with an CCL injury in one leg will go on to injure the other knee soon afterwards.
TPLO - Tibial Plateau Leveling Osteotomy Surgery
Rather than replacing the CCL with an artificial ligament through an Extracapsular Repair, TPLO surgery eliminates the need for the CCL ligament altogether by reconfiguring the knee.
TPLO surgery involves making a curved cut in the tibia from the front to the back, then rotating the tibial plateau (top section of the tibia) backward until the angle between the tibia and femur are appropriately level. A metal plate is then used to stabilize the two sections of tibia in the desired positions while the bone heals in its new configuration.
Recovery from TPLO Surgery
Healing from TPLO surgery is typically very quick, many dogs will be walking on the leg within 24 hours of surgery, and most will be bearing moderate amounts of weight on the leg within 2 weeks.
That said, it is extremely important to severely limit your dog's activity for a minimum of 4 months following TPLO surgery. Following your vet's instructions is essential in order to avoid further injury to the leg while your dog is recovering from the surgery.
Your dog should be able to return to full physical activity, including running and jumping, approximately 6 months after surgery.
