A dog can live comfortably with a torn CCL/ACL (cranial cruciate ligament) without surgery, but it requires strict "conservative management"—including 6–8 weeks of rest, weight loss, and bracing—and is generally only successful in small, older, or less active dogs. Large or active dogs typically require surgery to stabilize the knee, as a torn ligament causes instability, significant pain, and eventual arthritis.

What happens if you don't repair a torn ACL in a dog?

Your dog will begin favoring the non-injured leg. While the injured knee is becoming less and less used because of the partial tearing, additional pressure is put on the other knee. This is one reason why in 60% of cases, a cruciate ligament tear in one knee will later lead to an injury of the other knee.

What are the disadvantages of ACL surgery?

When performing reconstruction of the ACL, the major complications that can arise include missed concomitant injuries, tunnel malposition, patellar fracture, knee stiffness, and infection. We review the complications that can occur as a result of errors made before, during, and after surgery.

Can a fully torn ACL heal itself?

The short answer is no; a torn ACL cannot heal on its own because the ligament lacks the blood supply needed for regeneration. Unlike some tissues that have a high blood supply and can repair themselves, the ACL doesn't have the necessary resources to naturally reattach or heal itself once it is torn.

Is a torn ACL worse than a broken bone?

Broken Bones Heal Better Than Ligaments and Tendon

The short answer is because the bone has plenty of blood supply to it compared to ligament/tendon, which has very little and ligament/tendons are more complex to rebuild. Wounds generally heal more slowly if blood can't circulate properly.
