Evaluation of techniques for osteotomy tibial tuberosity advancement (TTA) and leveling tibial plateau osteotomy (TPLO) to cranial cruciate ligament deficience in dogs through locomotion kinetic analysis


Cranial cruciate ligament rupture is the major cause of lameness in dogs and can occur due to degenerative or traumatic causes. It can be associated with aging, abnormalities of conformation and immune-mediated arthropathies. It is a commonly observed disease in large breed dogs and its high prevalence made it one of the most studied diseases in veterinary orthopedics. Despite the wide variety of surgical techniques available, the ideal treatment for this orthopedic condition remains undetermined. Currently techniques have been developed to prevent abnormal movement of the stifle. Dynamic stability is achieved by changing the bone geometry by techniques like tibial plateau leveling osteotomy (TPLO) and osteotomy to advance the tibial tuberosity (TTA), currently being the most used surgeries. One of the main advantages of TPLO and TTA is the early weight-bearing in postoperative period,, which can be evaluated subjectively. But the locomotion kinetic analysis in pressure platform is a more objective measurement in the use of the limb during walking. The objective of this study is to compare the techniques of tibial tuberosity advancement (TTA) and tibial plateau leveling osteotomy (TPLO) in stabilizing dogs stifles with cranial cruciate ligament deficiency in one limb. Evaluation will be done with subjective and objective assessment via analysis in pressure platform (baropodometry). (AU)
