Overview of the tibial tuberosity advancement (TTA) procedure:

It has been widely accepted that a major factor causing the cranial cruciate ligament (CCL) to rupture is an abnormal force (shear force) which is a component of the total joint force generated through the stifle (knee) joint when the dog stands and walks. This abnormal force is due in large part to slope at the back of the tibial plateau.

The first method to dynamically eliminate the shear force was the tibial plateau leveling osteotomy (TPLO) designed by Dr. Barkley Slocum. This is accomplished by cutting the upper portion of the tibia and rotating the plateau until the slope is level to the ground surface. TPLO surgery has resulted in great success for stabilization of the stifle joint and restoration of limb function.
