Tibial Tuberosity Advancement (TTA) is a surgical procedure used to treat cranial cruciate
ligament (CCL) injuries in dogs. The surgery involves cutting the tibial tuberosity, the front part
of the tibia bone, and advancing it forward. This realignment changes the angle of the patellar
tendon, stabilizing the knee joint without relying on the damaged ligament.
During the procedure, a specialized implant or cage is placed to hold the tibial
tuberosity in its new position, allowing the bone to heal in its corrected alignment. This helps
prevent further joint instability and reduces the risk of arthritis development.
