Cranial Cruciate Ligament (ACL) Injuries
A cranial cruciate ligament injury, similar to an ACL tear in humans, is one of the most common causes of hind leg lameness in dogs. At Vet For Pet Animal Hospital, we diagnose and treat these injuries to restore your dog’s mobility.
Book OnlineThe cranial cruciate ligament stabilizes the knee joint. When it tears, partially or completely, it causes instability, pain, and swelling in the knee, often leading to sudden lameness in an affected leg.
Signs of a Cruciate Ligament Injury
Watch for sudden lameness, especially after activity, reluctance to bear weight on a hind leg, swelling around the knee, and stiffness after rest. Some dogs show a gradual onset if the tear is partial rather than complete.
How We Diagnose Cruciate Injuries
Diagnosis typically involves a physical exam to check for joint instability, along with X-ray imaging through our in-house diagnostics to assess the joint and rule out other causes of lameness, such as hip dysplasia.
Treatment for Cruciate Ligament Injuries
Most dogs with a torn cruciate ligament benefit from surgical repair to restore joint stability, particularly for active or larger dogs. Following surgery, CTX laser therapy can help manage pain and support faster healing during recovery.
Recovery and Rehabilitation
Recovery from cruciate ligament surgery typically involves restricted activity, pain management, and a gradual return to normal movement over several weeks. Follow-up visits help us track healing progress and adjust the recovery plan as needed.

Cruciate Ligament Injury FAQs
What causes a cranial cruciate ligament tear?
Tears can result from sudden trauma, but they’re also often caused by gradual degeneration of the ligament over time, especially in certain breeds.
Does my dog need surgery for a torn ACL?
Most dogs, especially larger or more active ones, benefit from surgical repair to restore stability and prevent long-term joint damage.
How long is recovery after cruciate ligament surgery?
Recovery typically takes several weeks to a few months, with restricted activity and a gradual return to normal movement.
Can a partial tear heal without surgery?
Some partial tears may be managed conservatively in certain cases, but many progress to full tears without surgical stabilization.
Will my dog fully recover after treatment?
Most dogs regain good function after surgery and rehabilitation, though some may develop mild arthritis in the joint over time.
Are certain dog breeds more prone to cruciate injuries?
Yes, larger breeds and dogs that are overweight are at higher risk of cruciate ligament injuries.
