KYON TTA & TTA-2 Course
Boston, Massachusetts

Since the invention of TTA by KYON founder, Slobodan Tepic, the procedure has been evolving. Unlike TPLO, a procedure strongly patented and closely curated during its early clinical development, TTA and the implants and instruments required to perform the procedure were not patented.

The result has been a significant variation in the quality and thoroughness of TTA instruction and, therein, surgical application. Several of the companies copying TTA offered abbreviated courses with little or no attention to planning and soft tissues. If you learned TTA at another training event, from a colleague, or online, it is highly likely that your TTAs are less than ideal.

As the inventor of TTA, we have a unique insight and commitment to, not only the device, but also the procedure. KYON has supported over 20 in vitro tests, several publications, and many posters and presentations. Our emphasis on preoperative planning and surgical execution is like no other TTA course. Our exceptional faculty of TTA instructors have contributed enormously to the refinement of the technique, conquering of challenging patients and understanding of clinical outcomes.

In early 2004, following three years of clinical testing, KYON launched the original Tibial Tuberosity Advancement (TTA) procedure for cranial cruciate deficiency in dogs. Slobodan Tepic, Dr. Sci., Dipl. Ing., and Prof. Pierre M. Montavon, Head of Small Animal Surgery at the School of Veterinary Medicine, University of Zurich, invented and developed TTA to allow neutralization of cranial tibial thrust without compromising joint congruency. At the time, this technique was a major departure from conventional practice. KYON’s TTA procedure has been performed in >100,000 procedures by more than 1,000 surgeons.

Throughout the last decade of clinical experience, KYON continued to refine and improve TTA preoperative planning, surgical technique, implants and instruments. In 2012, KYON in collaboration with Dr. Joop Hopmans began in vitro testing and, soon after, safety and efficacy testing to explore the next step in the TTA evolution, TTA-2*. TTA-2 consists of an incomplete osteotomy, performed with a novel hinged saw guide and a new cage, designed to transfer shear and compression forces. The simplified surgical technique preserves the periosteum on the medial aspect of the tibial tuberosity, eliminates stress risers created by the plate, fork, and screws, shortens the surgery time, and reduces the implant inventory. *patent pending
