Cruciate Ligament Repair: TTA Surgery

Mar 01 2022

What is the TTA surgery?

Tibial Tuberosity Advancement (TTA) is a popular surgical technique used to eliminate cranial tibial thrust in dogs suffering from Cruciate ligament rupture, or a torn ACL. TTA is one of two osteotomy procedures that aim to stabilize the stifle joint by changing its geometry. While not as technically demanding as the TPLO, the TTA requires advanced orthopedic equipment and proper case selection to minimize complications. If your pet needs orthopedic surgery, look no further than our veterinary clinic in Michigan for expert care and a successful TTA surgery recovery.

When it comes to TTA surgery for dogs, it's important to know that not all dogs are suitable candidates for the procedure. The Canton team takes a personalized approach to pet care, and our experienced veterinarians will evaluate your pet's condition to determine if TTA is the right choice for them. Dogs with a low patellar tendon insertion point, tibial plateau angle greater than 30 degrees, and/or angular limb deformities may not be good candidates for TTA. However, in some cases, TTA can be used to treat concurrent medial patellar luxation by adjusting the tension plate applied to the tuberosity. Our goal is to provide your pet with the best possible care and treatment plan for their unique needs. Contact us to schedule a consultation and learn more about TTA surgery for dogs.

General Information

a. Playing with other animals is not allowed during confinement. If there are other pets in your household, you will need to keep them separated. b. During confinement, your pet’s food intake needs to be reduced to help prevent weight gain. Most dogs will maintain their current weight if their food intake is cut in half. Water consumption should remain normal. c. The first two weeks following surgery you will need to monitor your pet’s incisions. Licking or chewing can cause infection or sutures to loosen. If you notice that your pet has started licking, you will need to take steps to discourage it from doing so. d. It takes a minimum of six to eight weeks for bones to heal. e. One of the most difficult aspects of confinement is that the animals will frequently feel better long before they are healed. At this point, your pet will start being more careless of the operated limb and is then more likely to be overactive and injure itself. Until the bone is healed, you must adhere strictly to the confinement guidelines and not allow your pet to do more. f. If your pet is jumping or bouncing in its confined area, it is being too active. Tranquilizers may be required to help alleviate your pet’s anxiety or control its activity. g. If at any time during your pet's recovery and healing it does anything that causes it to cry out or give a sharp yelp, contact your veterinarian. h. Following surgery your pet should always maintain its current level of function, or improve. If at any time during your pet’s recovery and healing it has a setback or decrease in function, contact your veterinarian. I. It is imperative that you inform your veterinarian at once if your pet does something that is potentially harmful to the surgery. If something has occurred that jeopardizes the outcome of surgery, it is usually less difficult to correct if it is caught right away, which leads to a better outcome for your pet. j. If your pet is too active during its confinement it may injure itself or slow healing which increases the amount of time your pet must be confined. k. Follow-up appointments are usually needed two weeks post-operatively to monitor incisions and healing. At eight weeks post-operatively radiographs are taken at which time your pet is started on a regulated activity regime. A final appointment at four months post-operatively is needed for additional radiographs and final instructions before returning your pet to normal activity.

Slocum® Rehabilitation Regime:

  • Once radiographs have confirmed bone healing, usually around eight weeks post-operatively, the rehabilitation regime is initiated.

  • During this period the patient's activities are gradually increased to build muscle, stretch scar tissue from surgery, and strengthen bone healing.  The degree of activity should progress with your pet remaining comfortable.  Since increasing duration, not intensity is the goal, explosive activities, such as running, jumping, or playing, are not allowed during the rehabilitation period.

  • Throughout the rehabilitation process, the dog is allowed to go as far as it is able while remaining comfortable.  To judge your pets’ comfort, watch the dog when it gets up following exercise and rest.  If invigorated and excited about more activity, the animal is comfortable.  If the dog gets up with stiffness and complaint, then the amount of activity should be reduced.

  • The first three to four weeks of rehabilitation are comprised of progressively longer walks with the animal on a short lead, in the heel position.  Begin with a five-minute walk, and see how the dog responds.  If the dog does well, continue at this distance for three to four days.  If your pet has remained comfortable during this time, double the distance of the walk.  Monitor the dog’s comfort and after three to four days, double the distance of the walk again.  Continue doubling the distance of the walk every few days as the dog’s comfort level permits.  If the animal appears to be uncomfortable with the increased distance, cut the length of the walk back to the last distance at which it was comfortable; go for another few days at the lesser distance, then try doubling it again.  

  • Your pet will benefit more from several short walks in one day rather than a single long walk, so instead of doubling the length of a walk, you can double the number of walks.  Rather than going from one 10-minute walk to one 20-minute walk, go for two 10-minute walks instead.  Your pet will still be getting twice the activity, but it will be split up throughout the day.  You can continue doubling the distance or number of walks as your schedule and your pet's comfort allow.  If your pet likes the water, you may substitute a swim for a walk at any time, allowing the swim for the same length of time as the walk you are replacing.  Your dog should not, however, be allowed to launch itself into the water, but rather be encouraged to swim after it is already belly deep.

  •  During the fourth through the sixth week of rehabilitation, the walks are continued with your dog on a long lead, such as a 10–15-foot leash or a flexible lead.  You will need to cut back the length of the walks you are currently going, as the longer lead allows the dog the freedom to trot back and forth, increasing its usage of the leg.  Usually, we recommend that you quarter the distance you are currently going on the short lead walks.  Once you know where your pet's comfort level is, you will double the amount of activity every few days.  As distances are more difficult to judge at this point, it is important to monitor the dog's comfort level closely during this stage of rehabilitation.

  • During the seventh through the ninth week of rehabilitation, your pet is allowed very mild activity off-lead.  You will continue with the long lead walks and you will start letting your pet have time off lead in the yard, under your supervision.  The area should have no other animals or distractions around.  The off-lead activity should occur after your pet has had a walk to get some energy out of its system.  Start with five minutes off lead following a walk.  As with the walks, double the time your pet is spending off lead in the yard every few days as long as your pet's comfort level permits.  The dog should remain under the voice control of the owner at all times.  No jumping, chasing a ball, frisbee, or playing with other animals is permitted.  Avoid any activities where the dog's full concentration is thrown into the activity without regard for its body.

  • A final checkup at the end of the rehabilitation process is needed before full activity may be resumed.
