The cranial cruciate ligament (CCL) in dogs is similar to the ACL in humans; it is a tendon along the leg that can tear and lead to great injury if left untreated. Here, our Concord vets discuss TPLO surgery as a method of treating torn or injured CCL in dogs.
Tibial Plateau Leveling Osteotomy (TPLO) Surgery
Should your canine companion tear their cranial cruciate ligament, your vet will likely advise surgery to correct it. The surgery used to repair the cruciate ligament is called TPLO, short for Tibial Plateau Leveling Osteotomy. The surgery can help your dog get back to running and jumping like normal!
Unlike other surgeries, TPLO restores mobility to your dog's knee without relying on the damaged ligament for stability.
Tearing the CCL is Painful
If your dog has a torn cruciate ligament, pain arises from the knee's instability and a motion called 'tibial thrust'.
Tibial thrust is a sliding movement caused by the transmission of weight up a dog's shin bone (tibia) and across the knee, causing the shinbone to jump forward in relation to the dog's thigh bone. This forward "thrust" movement occurs because the top of a dog's tibia is sloped, and can not prevent unwanted movement.
Details of TPLO Surgery
TPLO surgery eliminates the need for the cranial cruciate ligament by reconfiguring your dog's knee.
To perform TPLO surgery, a surgeon makes a curved cut to the patient's tibia before rotating the tibial plateau (top section) to level the tibia and femur. Once the tibial plateau is in the desired position the TPLO surgery is completed by attaching a metal plate to stabilize the knee as it heals around the new configuration.
Recovering From TPLO - Dog Recuperation Times
Following TPLO surgery, dogs will be able to walk on the leg within 24 hours, and most will be bearing moderate amounts of weight on the leg within 2 weeks.
Recovering from TPLO surgery is a long process for dogs, but the recovery time for TPLO surgery is still much shorter than comparable surgeries, coming in at around 12-16 weeks. Expect your dog to return to full physical activity approximately 6 months after TPLO surgery.
What to Do if Your Dog Jumped After TPLO Surgery
Following your vet's post-operative instructions will help your dog to avoid re-injuring the leg while it's still healing. Your dog should not be permitted to run or jump after TPLO surgery until the knee has had time to heal. However, incidents might still occur. No one is perfect, and unfortunately, there's no way to explain to our dog friends what TPLO surgery is.
You'll want to contact your veterinarian if you notice any of the following symptoms:
- Loss of appetite
- Missing staples or stitches
- Signs of infection or inflammation at the incision site
- Diarrhea or vomiting
- Reluctance to put weight on recovering leg
- Sensitivity to pain medications
Your vet will be able to examine your pup for signs of complications and treat any issues before they become more severe.
