TTA Clinical Development

website_squares.029

Over the course of two years, starting in December 2001, some 150 clinical procedures were performed, mostly at the University of Zurich, to refine the surgical approach and the implant design.  Trial and error in the first year was followed by a more focused development phase in the second year.  Controlled clinical release of the TTA system was initiated in early 2004.

Clinical experience with several hundred cases during the first nine months of 2004, by 50 surgeons in the United States, Europe and Japan demonstrated reduced complexity and morbidity of the procedure in comparison to TPLO.

Early complication rates were manageable.  In most cases, complications were related to technical errors, such as incorrect placement of the implants and inaccurate location and/or orientation of the osteotomy.

By the end of 2004, TTA was fully released into clinical use.  By 2009, over 50,000 cases have been performed by more than 700 surgeons world wide.  While positive reports on the technique and short-term clinical outcomes are encouraging, the most important benefits and advantages of TTA are expected in long-term trouble-free performance.
