Torn CCL (ACL) in Dogs
A torn cranial cruciate ligament, often referred to as a dog's ACL, is one of the most common orthopedic injuries we see at Animal Surgical Care of PA. Understanding the signs and treatment options can help you get your dog back on their feet faster and more comfortably.
The cranial cruciate ligament stabilizes the knee joint, and when it tears, dogs typically show sudden or gradual hind-limb lameness, difficulty rising, and reluctance to bear weight on the affected leg. Larger, more active breeds are especially prone to this injury, though any dog can be affected, and some develop partial tears that worsen over time if left untreated.
Diagnosis begins with a physical exam to check for joint instability, often followed by radiographs to confirm the extent of ligament damage and rule out other conditions. Left untreated, an unstable knee accelerates cartilage wear and leads to progressive arthritis, so early evaluation matters.
Treatment typically involves surgical stabilization, and our team offers several proven approaches through our cruciate surgery program, including TPLO, extracapsular repair, and TTA, chosen based on your dog's size and activity level. For partial tears, a modified technique such as PPLO may also be appropriate.
If your dog is limping or favoring a hind leg, contact Animal Surgical Care of PA at (484) 886-8612 to schedule a diagnostic evaluation and discuss the treatment plan that fits your dog's needs.
Torn CCL (ACL) in Dogs FAQs
What are the signs of a torn CCL in dogs?
Signs include limping, stiffness after rest, reluctance to bear weight on a hind leg, and visible swelling around the knee.
Can a torn CCL heal without surgery?
Most dogs, especially larger breeds, do not regain full stability or comfort without surgical repair, and delaying treatment often leads to worsening arthritis.
What surgical options are available for a torn CCL?
Options include TPLO, extracapsular repair, TTA, and PPLO for partial tears, chosen based on your dog's individual needs.
How is a CCL tear diagnosed?
A physical exam checking for joint instability, along with radiographs, confirms the diagnosis and extent of damage.
Is a CCL tear the same in both knees?
Not necessarily. Dogs with one torn CCL have an increased risk of tearing the other knee's ligament over time, so both legs are monitored.
How long does recovery take after CCL surgery?
Most dogs recover within 8 to 12 weeks with rest and a gradual return to activity guided by our surgical team.
