There are three canine ACL repair options:
1. External Capsular Repair
This was the original repair technique and essentially involves placing bands of very strong suture material around the stifle to stabilize the knee joint. This can be a good option for canine ACL repairs in smaller or less active dogs.
2. Tibial Tuberosity Advancement Surgery (TTA)
This procedure involves cutting the front part of the top of the tibia (the bone between the stifle and the tarsus, or ankle joint). The fragment is rotated slightly forward and upward, then held in place with a metal plate and screws. This surgery changes the forces acting on the stifle and recruits the large, powerful quadriceps muscles to keep the tibia in its normal position during standing. The TTA procedure is considered by many veterinary orthopedic surgeons to be one of the best methods for repairing a torn ACL in dogs.
3. Tibial Plateau Leveling Osteotomy (TPLO)
This technique involves cutting the back part of the top of the tibia. The fragment is rotated slightly backward and downward, then held in place with a metal plate and screws. This surgery creates a flat surface, as opposed to a sloped surface, for the femur (thigh bone) to sit on, so it does not slip backwards on the tibia during standing.
Our Expertise in Veterinary Orthopedics
Dr. Hess has performed hundreds of successful extra-capsular repairs during his career. After being trained by one of the top veterinary orthopedic surgeons in Canada, he is proud to also offer Tibial Tuberosity Advancement Surgery (TTA) for our patients.
Dr. Hess and the team at Acton Veterinary Clinic have performed many surgeries for cranial cruciate ligament repair with the TTA procedure, all with very successful outcomes. After a diagnosis of CCL rupture, Dr. Hess will be happy to discuss your dog's individual case and recommend the procedure best suited for your dog. Our goal is to return function of the injured leg to as close to normal as possible.
