What to Expect at the Vet

A torn cranial cruciate ligament (CCL, equivalent to the human ACL) is one of the most common orthopedic injuries in dogs. Without surgical repair, the knee joint becomes unstable, leading to chronic pain, arthritis, and meniscal damage. TPLO (tibial plateau leveling osteotomy) is the gold-standard surgical treatment, though lateral suture techniques are an option for smaller dogs.

This is classified as a moderate emergency. Seek care today.

Note: Up to 60% of dogs who tear one CCL will tear the other within 1-2 years. TPLO has the strongest outcomes for dogs over 30 lbs. Lateral suture is less expensive but may not hold up as well in large, active dogs. Post-operative physical therapy is standard practice.

Your veterinarian will perform an initial examination ($75-$150) followed by diagnostic tests ($250-$600) to determine the appropriate treatment approach. Treatment costs ($1,500-$4,000) vary based on the specific intervention needed. Hospitalization and monitoring ($675-$1,250) may be required.
