Resumo
Background: The most common conditions that compromise the stifle joint in dogs are medial patellar luxation (MPL) and cranial cruciate ligament (CCL) rupture. Surgical procedures are usually indicated for the treatment of these diseases. One ordinarytechnique for the treatment of MPL is the tibial tuberosity transposition, and one prominent technique for CCL rupture is the tibialtuberosity advancement. These techniques can be associated in one surgical procedure called tibial tuberosity transposition andadvancement (TTTA) for the simultaneous treatment of both stifle diseases. The aim of this study is to report the surgical treatmentof a dog with MPL and CCL rupture affecting the same joint by the TTTA technique with the use of a TTA-Maquet cage-only.Case: A 3-year-old Pitbull dog weighing 39 kg was attended at Veterinary Hospital with a history of marked lameness in theleft pelvic limb. The orthopedic examination showed positive results for cranial drawer motion and tibial compression tests,and a complete CCL rupture was diagnosed. The presence of patellar luxation was evaluated by manual pressure on the patella, and grade 3 of MPL was diagnosed. Both conditions were affecting the same stifle joint. In addition, survey radiographsof the affected joint were performed. Surgical treatment was indicated by the TTTA technique. Radiographic measurementswere taken to calculate the cranial tibial tuberosity advancement by the tibial plateau and the common tangent methods, and atitanium TTA-Maquet cage-only of 10.5 x 20.0 mm was selected. Linear osteotomy was performed on the tibial tuberosity withthe aid of an oscillating saw, based on the Maquet hole technique. The tibial tuberosity was carefully displaced cranially and thecage was inserted at the site of osteotomy. The cage ears were molded on the tibial surface and fixed with 2.4 mm self-tappingcortical screws...(AU)
