Cranial cruciate ligament rupture is the most common orthopedic injury in dogs, causing acute pain and progressive joint deterioration that requires surgical intervention for optimal welfare outcomes.
Cruciate ligament rupture causes acute, severe pain that makes normal weight-bearing impossible. Dogs with this injury experience immediate lameness and ongoing joint instability that worsens with each step. Without surgical stabilization, the knee joint deteriorates progressively through chronic inflammation and arthritic change — converting an acute injury into a chronic pain condition. Surgical repair with appropriate rehabilitation restores function and prevents this deterioration, making it both the welfare-positive and the long-term cost-effective choice in most cases. Post-operative pain management and rehabilitation are as important as the surgery itself for achieving good welfare outcomes.
