TTA Procedure

Tibial Turbercle Advancement

Devised by Slobodan Tepic (Kyon, Zurich) and Professor Pierre Montavon (University of Zurich), Tibial Turbercle Advancement (TTA) is a biomechanically tested and proven surgical procedure for treatment of dogs with cranial cruciate ligament injuries with well over 90,000 dogs treated worldwide since 2004.

TTA neutralises tibial thrust reducing instability and decreases femoro-tibial stresses and retro-patellar pressure reducing joint pain and articular cartilage damage.

Mark was one of the first veterinary orthopaedic surgeons in the United Kingdom to adopt the TTA procedure at the end of 2004 and has introduced the updates in technique as they have developed.

Low complication rates:

Internal audit of 100 consecutive TTA surgeries at Ossicle 2011-2012.

  • 8% late meniscal cartilage tears.
  • 1% incidence of post surgical fractures and implant failure.
  • less than 1% post operative infection rate

In 2009 Ossicle provided 13 patients that had undergone one-sided TTA surgery for completely independent assessment of their outcomes by the School of Clinical Veterinary Science and the Centre for Comparative and Clinical Anatomy at the University of Bristol. The results of the study eventually published in 2012 in the Veterinary Surgery journal.

‘Eleven to 20 months after unilateral TTA, dogs had very high subjective owner VAS scores for limb use and owner satisfaction and near symmetrical MTP vertical forces, all indicating an excellent return to normal limb use by standard force plate variables.’
