The cranial cruciate ligament, often called the ACL, helps keep the knee stable. A torn ACL is one of the most common causes of hind leg lameness in dogs. It can happen suddenly during play or develop slowly as the ligament weakens over time.
Without treatment, an unstable knee can lead to ongoing pain, damage to the cartilage and arthritis. ACL repair surgery stabilizes the knee so your dog can walk, run and play more comfortably.
Signs of a Torn ACL
A torn ACL can cause sudden lameness or a limp that comes and goes. Watch for:
- Limping or holding up a back leg
- Stiffness, especially after rest
- Trouble getting up, jumping or climbing stairs
- Sitting with one back leg stuck out to the side
- Swelling around the knee
- Less interest in walks or play
Your vet will examine the knee and may recommend X-rays to confirm the diagnosis and check the joint.
Surgery and Recovery
There's more than one way to repair a torn ACL. Your vet will recommend the best option based on your dog's size, age, activity level and overall health, and will explain what each choice involves.
Recovery takes time and patience. Most dogs need several weeks of restricted activity, with short leash walks and no running or jumping, followed by a gradual return to normal exercise. Pain medication, rechecks and home exercises help your dog heal as well as possible.
