Tibial Tuberosity Advancement: Principles and Operation Technique of TTA Rapid

Tibial Tuberosity Advancement: principles and operation technique of TTA rapid

The first question that should arise is: “Why do we advance the tibial crest?” The answer to this question generates a staged process of explanations.
• The quadriceps is the strongest muscle in the body.
• The ultimate goal is to bring the patellar ligament perpendicular to the tibial plateau when the stifle is held in a standing angle of 135°.
• The patellar ligament is normally about 100° to the tibial plateau when the stifle is held in a standing angle of 135°. • When the stifle is gradually flexed, the angel between the patellar ligament and the tibial plateau gradually decreases
• During stance, the cranial cruciate ligament is maximally loaded. However, when the stifle is flexed gradually, the tension in the cranial cruciate ligament decreases. At a certain angle of flexion during stance, the tension of the cranial cruciate ligament shifts towards the caudal cruciate ligament: this is when the patellar ligament is 90° to the tibial plateau.
