How does the TTA procedure work?
Research shows that if the angle between the patellar tendon and the tibial plateau could be reduced to a perpendicular (90 degree) angle, then weight-bearing strain would be redistributed so that the joint would be stabilized and the CCL would not be needed. The TTA involves an osteotomy (a cut made in bone) in the non-weight bearing portion of the tibia, just behind the tibial tuberosity. The tibial tuberosity is advanced to align the patellar tendon perpendicular (90 degrees) to the tibial plateau slope. This new alignment eliminates the need for a CCL and results in a stable joint. The advanced tibial tuberosity is secured using titanium implants. A bone graft is packed in the open area of the osteotomy to speed up healing which takes about 8 weeks.
Does my pet have to spend the night in the hospital?
In most cases , we like to keep the patient one night.
Will this procedure have a negative affect on the opposite leg?
No. TTA repair of CCL tears has no negative affect on the opposite leg. In fact, early TTA repair and subsequent early return to function in the affected leg may decrease the stress on the unaffected leg.
Will the opposite knee have the same problem?
Forty percent of all dogs with CCL rupture on one side will develop the same problem on the opposite side sometime in the future. The most effective ways to decrease this percentage are early surgical repair of the first leg to allow for even weight distribution and weight loss in overweight dogs.
Is TTA only for large dogs?
No. Small breed dogs also have an excellent outcome following TTA.
Is the postoperative period more difficult following TTA than following other techniques?
Absolutely not. Because the TTA involves an osteotomy in a non-weight bearing portion of the bone, patients are very comfortable and recover more quickly that with all older techniques including TPLO. Most patients are weight bearing in 1-2 days.
Will my pet have pain after the TTA surgery?
Some post operative discomfort is unavoidable and all patients vary in their response to surgery. All dogs undergoing TTA at Serra Veterinary Hospital Inc. will be started on a carefully implemented pain management plan before, during and after surgery. This protocol includes CRI (continuous infusion) of intravenous pain medications (including Morphine) during their overnight stay, as well as a pain patch and oral pain medications to take at home. Most clients feel their pet’s discomfort level is minimal.
How long does it take for the leg to heal?
The osteotomy takes 6-8 weeks to heal. During this time your pet can have a reasonable amount of short leash controlled activity.
What kind of follow-up can we expect?
We will schedule recheck visits at 2, 4 and 8 weeks. At the 2 weeks visit sutures will be removed. At the 8 week visit radiographs will be taken to evaluate bone healing.
How much does this surgery cost?
Our fee for the TTA procedure range from $2800.00-$3000.00. This cost is a bit more than the traditional extra capsular procedure but similar to the TPLO procedure. While this surgery is technically more sophisticated than older procedures and uses expensive titanium implants, we are attempting to make it as affordable as possible so that pet owner won’t have to settle for a less successful alternative procedure.
