Multiparametric Comparison of Two TTA-Based Surgical Techniques in Dogs with Cranial Cruciate Ligament Tears

Simple Summary The rupture of the cranial cruciate ligament is one of the most common causes of hindlimb lameness in dogs. In this study, we compared two different tibial tuberosity advancement (TTA)-based surgical techniques to treat this condition. No significant differences were found when both procedures were analyzed using different assessment parameters.Abstract Tearing of the cranial cruciate ligament causes hindlimb lameness in dogs. Different surgical procedures have been proposed to treat this condition. In this study, two different TTA-based techniques and implants were compared. A total of 30 dogs were separated into two groups according to the technique and implant used (Porous TTA (R) or Model Xgen (R)). The aim of the study was to assess whether one of these techniques has better functional recovery of the joint, better bone consolidation after the osteotomy procedure and fewer osteoarthritic changes. We compared both groups up to 3 months after surgery. No significant differences were found in any of the assessed parameters. Thus, both procedures were found to be equally effective and safe.
