Tibial Tuberosity Advancement

The Tibial Tuberosity Advancment (TTA) is an orthopedic surgery to repair the damage done by a torn Cranial Cruciate Ligament (CCL). The CCL works just like the ACL in the human knee. It prevents forward movement of the Femur (thigh bone) over the Tibia (shin). When torn your pet may show signs like limping or standing with a "toe touch" appearance like a tired horse.

To correct this problem the surgeon will adjust the angle of the Patellar Tendon. The patellar tendon is attached to the Femur, stretches across the Patella (knee cap), then attaches to the Tibia below. During surgery the Tibial Tuberosity is moved forward to change the angle of the tendon. The surgeon then uses a cage, fork, and plate to maintain the angle. The hardware is made from titanium and designed to stay in the body permanently.

Recovery is fairly straightforward. Most pets will be bearing some weight by the time of the suture removal. After about 2 weeks the pet may go on walks with a SHORT leash. No running, jumping, or playing. Usually recover is compleated by the end of 8 weeks.
