Tibial Tuberosity Advancement (TTA)

Tibial Tuberosity Advancement (TTA) is an advanced orthopedic procedure used to treat cranial cruciate ligament (CCL) injuries in dogs. The cranial cruciate ligament is a critical stabilizing structure in the knee (stifle) joint, and when it ruptures or degenerates, it causes pain, instability, and progressive arthritis.

Rather than replacing the damaged ligament, TTA works by altering the biomechanics of the knee. During the procedure, the tibial tuberosity (the front portion of the shinbone where the patellar tendon attaches) is carefully advanced forward and stabilized with specialized implants. This change neutralizes the abnormal forces within the joint, restoring functional stability during weight-bearing.

TTA surgery is commonly recommended for active dogs and medium-to-large breeds, and it allows for reliable stabilization while preserving normal joint motion. The procedure is designed to reduce pain, improve limb function, and slow the progression of arthritis.

Most dogs begin weight-bearing shortly after surgery, with a structured rehabilitation and recovery period over several weeks. With proper post-operative care, pain management, and gradual return to activity, the majority of patients regain excellent limb function and return to a comfortable, active lifestyle.
