Torn Ligaments in Dogs' Legs

While ligament tears are common injuries in humans, ACL tears are common in dogs as well. ACL ligament tears are one of the most common causes of leg lameness in various canine breeds. It is important for dog owners to recognize the symptoms of ligament tears and understand their treatment options.

  1. Characteristics of a Ligament Tear

    • The ACL ligament in dogs sits between the tibia and the femur in the knee in order to prevent friction between bones. When the ACL tears, these bones have a free range of motion, which causes the femur and the tibia to rub together. This tear causes great pain for the dog and results in inflammation and lameness that can ultimately lead to arthritis. In older dogs, chronic ligament tearing is attributed degenerative aging, weight gain and genetics. An acute ligament tear occurs when a dog hyperextends its knee jumping or running.

    Symptoms

    • Common symptoms of ligament tears in dogs are decreased range of motion, exercise intolerance, stiffness, limping and a knee that is tight or hard to the touch. Many dogs will wince when their torn ligament is touched and will not place their entire weight on the affected area when sitting. While symptoms vary by breed and by individual, it is best to schedule an appointment with you vet as soon as your dog begins to show signs of a potential tear.

    Non-Surgical Treatments

    • Dogs diagnosed with an ACL ligament tear have many non-surgical options for recovery. The most important thing an injured dog can do is rest its leg. Although it is difficult, make sure that your dog is not engaging in any prolonged exercise or sudden movements. Additionally, your vet may prescribe an anti-inflammatory or pain medication for your dog. Smaller dogs have a better chance of making a complete recovery without any surgical intervention.

    Surgical Treatments

    • Depending on the severity of the ligament tear, your dog may require surgery. There are several types of ligament surgery. Talk to your vet about which surgery will best meet your dog's needs. Many dogs will be required to stay overnight for evaluation following surgery. Recovery time for a canine ligament surgery can range anywhere from six to 14 weeks. During the recovery period, it is imperative that your dog rest as much as possible. Exercise will gradually be added back into your dog's routine until it has made a full recovery and can walk without pain.
