TTA knee surgery is a cutting-edge orthopaedic procedure designed to address CCL injuries in dogs. The cranial cruciate ligament, analogous to the anterior cruciate ligament (ACL) in humans, plays a crucial role in stabilizing the knee joint. When this ligament becomes damaged or torn, it can result in lameness, pain, and decreased mobility in dogs. TTA surgery aims to correct this issue by altering the biomechanics of the knee joint, thereby reducing stress on the damaged ligament and promoting healing.
