Tibial tuberosity advancement (TTA) is an orthopedic procedure to repair deficient cranial cruciate ligaments in dogs. It has also been used in cats. This procedure was developed by Dr. Slobodan Tepic and Professor Pierre Montavon at the School of Veterinary Medicine, University of Zurich, in Zurich, Switzerland beginning in the late 1990s.
The pivot-shift test [1] is one of the three major tests for assessing anterior cruciate injury or laxity, the other two being the anterior drawer and Lachman test. However, unlike the other two, it tests for instability, an important determinant as to how the knee will function. [ 1 ]
Dog's titanium TPLO implant [1]. TPLO, or tibial-plateau-leveling osteotomy, is a surgery performed on dogs to stabilize the stifle joint after ruptures of the cranial cruciate ligament (analogous to the anterior cruciate ligament [ACL] in humans, and sometimes colloquially called the same).
The pivot-shift test involves flexing the knee while holding onto the ankle and slightly rotating the tibia inwards. [28] In the anterior drawer test, the examiner flexes the knees to 90 degrees, sits on the person's feet, and gently pulls the tibia towards themself. [29] The Lachman test is performed by placing one hand on the person's thigh ...
The triple tibial osteotomy is a surgical procedure used to treat dogs that have completely or partially ruptured the cranial cruciate ligament in one or both of their stifles. [1] The cranial cruciate ligament connects the femur with the tibia , which functions to stabilise the canine stifle joint from the forces put on it during exercise and ...
It can be associated with damage to the anterior cruciate ligament. [1] Patellar luxation is a common condition in dogs, particularly small and miniature breeds. [2] The condition usually becomes evident between the ages of 4 and 6 months. It can occur in cats, as well, especially domestic short-haired cats. [3]
The cranial cruciate also resists over-extension and inward rotation, and is the most commonly damaged stifle ligament in dogs. "Cushioning" of the joint is provided by two C-shaped pieces of cartilage called menisci which sit between the medial and lateral condyles of the distal femur and the tibial plateau.
The cranial cruciate ligament (CrCL) stabilizes the dog knee much like the anterior cruciate ligament (ACL) does in humans. There are several modalities currently being used in the treatment of cranial cruciate ligament (CrCL) deficiency, which is a common and costly problem in dogs and sometimes cats.
