Tibial Tuberosity Advancement (TTA & TTA-2)

website_squares.022

Surgical repair of cranial cruciate deficiency is one of the most common small animal orthopedic procedures, due not only to the high incidence of the problem, but also to the clinical success of recent surgical techniques.

KYON launched TTA for cranial cruciate deficiency in dogs in early 2004, following three years of clinical testing.  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, have developed  TTA to allow neutralization of cranial tibial thrust without compromising joint congruency. This technique was a major departure from conventional practice. Since 2004, KYON’s TTA procedure has been used in over 100,000 cases by more than 1,000 surgeons and has become an important addition to the canine cranial cruciate repair armamentarium. read publications on Tibial Tuberosity Advancement>>

TECHNICAL FEATURES:
• Sound biomechanical rationale
• Simplified surgical procedure
• Unique implants designed specifically for TTA
• Superb biocompatibility of titanium
• Broad range of sizes available
BIOLOGICAL BENEFITS:
• TTA neutralizes cranial tibial thrust in cranial cruciate deficient stifles.
• Stability is achieved without compromising joint congruency.
• TTA decreases internal joint reactions including retro-patellar pressure.
• TTA is less invasive than other geometry modifying techniques.
• TTA reduces morbidity and post-surgical complications while accelerating recovery.



The rapid acceptance of TTA has motivated several other companies to offer similar implants. KYON has neither collaborated with nor endorsed any of the competitors in the manufacture, promotion or sale of their TTA systems. KYON Veterinary Surgical Products is the only authorized distributor of KYON products in the United States.

The TTA-2 Innovation

website_squares_tta-2-2.021.021

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. TTA-2 implants are packaged sterile for surgical convenience. In vitro and in vivo studies have demonstrated that the saw guide and surgical planning for its use, combined with the use of the Fine Touch Osteotomy Spreader minimizes the risk of intraoperative or early postoperative fracture of the tuberosity.

With 2 years of clinical experience and over a decades’ experience in the basic mechanical and biological principles behind tibial tuberosity advancement as a geometry modifying procedure, TTA-2 was made commercially available in spring 2014. TTA-2 has the potential to reduce iatrogenic trauma, reduce the risk of infection, accelerate the incorporation of the implant into the bone and shorten the surgery time, thus providing surgeons and their patients with tangible benefits.
