The TTA procedure developed by Tepic and Montavon is designed to bring the tibial plateau to sit at 90 degrees to the straight patella ligament. This effectively neutralizes the shear forces within the stifle, under loading, making the stifle stable.
This is achieved by advancing the tibial tubercle and stabilizing the created defect using a titanium cage and plate. The cage is selected for both thickness and width.
The implants are secured using titanium screws. Titanium is very osteoconductive resulting in rapid healing. The use of stainless steel implants is not recommended.
