Canine cruciate ligament injury
Rupture of the canine cranial cruciate ligament (CCL) is the most common orthopaedic problem seen in veterinary practice. The CCL in dogs is a band of tough fibrous tissue that attaches the femur to the tibia, thereby preventing the knee joint from over-extending or rotating. Trauma to this ligament in dogs is usually caused by the slow degeneration over time, which can trigger a cascade of events resulting in knee pain and lameness.
Tibial tuberosity advancement
One routine surgical procedure for CCL repair is tibial tuberosity advancement (TTA), involving a cut being created in the tibia to allow a change in geometry in such a way that the CCL is no longer necessary to maintain stability.
