Title: Comparison of Tibial Tubersosity Advancement to Tibial Plateau Leveling Osteotomy for Cranial Cruciate Insufficiency in Dogs
Annual Direct Cost: $5,500
Project Period: 07/01/2011-06/30/2013

DESCRIPTION (provided by applicant): Rupture of the cranial cruciate ligament (CCL) is a common cause of hindlimb lameness and osteoarthritis (OA) in dogs, reliably leading to chronic pain and disability if left untreated. The cost of medical and surgical management of this disease has been estimated to be over $1 billion annually. Although several surgical techniques have been described, not one of them has consistently resulted in reestablishment of normal joint function. The three surgical procedures most commonly performed are the extracapsular reconstruction (ECR), tibial plateau leveling osteotomy (TPLO) and tibial tuberosity advancement (TTA). This last technique has not yet been evaluated in a rigorous head-to-head comparison versus the other surgical techniques. It is of utmost importance to compare this procedure to the others available, especially the TPLO. 

The objective of the present study is to compare the forceplate gait analysis before and after TTA to TPLO and ECR and to determine if there is an objective difference in the short and long-term outcomes of these three surgical techniques and how this outcome compares to normal dogs.
