We offer surgery to repair cruciate ligament injuries. Our doctors will discuss the best approach for your pet. The cruciate ligament can get injured due to trauma, most frequently a twisting injury or ligament degradation. This typically occurs when your pet is exercising or abruptly shifts its direction. Some animals are prone to ligament injury because their ligaments are weak. Depending on the severity and weight of the animal, a cruciate rupture can be repaired using a variety of methods.
