TPLO surgery costs $3,000-$6,000 per knee - 50% of dogs tear the other too. The cranial cruciate ligament (CCL, dog's ACL) is one of the most common orthopedic injuries, causing sudden limping, an unstable joint, and progressive arthritis without surgical repair.

What Is a Cruciate Ligament Tear
The cranial cruciate ligament stabilizes the knee joint. In dogs, it typically degenerates gradually rather than tearing from a single traumatic event. Obesity, genetics, poor conformation, and repetitive stress contribute. Partial tears become complete tears over time. About 50% of dogs tear the other knee eventually.

Symptoms

What to Watch For
Sudden limping on a hind leg. Sitting with the leg stuck out to the side. Stiffness after rest. Knee swelling. Clicking when walking. Hesitating to jump, run, or climb stairs. Your dog shifts weight to the front legs. Can be sudden or gradual onset.

Diagnosis

$200-$500
Orthopedic exam ($75-$150) with drawer and tibial thrust tests for knee instability. X-rays ($150-$300) assess arthritis and rule out other causes. Tense or painful dogs may need sedation for the evaluation. MRI is rarely needed. Average $200-$500.

Treatment

$3,000-$6,000/knee
TPLO (tibial plateau leveling osteotomy) is the gold standard at $3,000-$6,000. TTA (tibial tuberosity advancement) has similar cost and outcomes. Lateral suture ($1,500-$3,000) works well for small dogs. Conservative management with rest, bracing, and pain meds ($500-$1,500) suits small dogs or when surgery isn't feasible. Average $3,000-$6,000 per knee.

Total Cost

$3,000-$12,000+
One knee is $3,000-$6,000. If both knees tear (50% chance), double it. Add ongoing arthritis management. $3,000-$12,000+ total.

Certain Breeds

Higher Risk
Labrador Retrievers, Rottweilers, Golden Retrievers, and German Shepherds top the list. Large, active breeds are most susceptible.

Recovery

8-16 Weeks
Strict rest for 8 weeks. Gradual return to activity over 8-16 weeks. Physical therapy improves outcomes a lot.

Prevention
Keep your dog at a healthy weight. Avoid sudden stops and sharp turns on slippery surfaces. Regular exercise strengthens the muscles. Weight management is key.

Insurance Traps

CCL tears are the most common expensive orthopedic claim. Insurance matters here.

Coverage Basics

Coverage
Most accident/illness policies cover cruciate surgery if you enroll before the limping starts. CCL tears are classified as injury or degenerative condition - this distinction affects coverage. Most comprehensive plans cover both.

The Bilateral Clause

Bilateral
Critical fine print: if your dog tears one cruciate before enrollment, some insurers exclude both knees as pre-existing. They assume underlying degeneration affects both. Check your policy's bilateral condition clause carefully.

Cost vs Deductible

Deductible
At $3,000-$6,000 per knee, TPLO is where insurance delivers the most value. Bilateral tears cost $6,000-$12,000. With 80% reimbursement, insurance saves $4,800-$9,600 on bilateral cases.

Orthopedic Waiting Period

Waiting period
Many policies have a 6-month orthopedic waiting period. Some insurers waive it with a clean vet exam. CCL tears happen at any age, so this waiting period matters less than it does for puppy conditions, but don't delay enrollment.

Common Questions

Real answers about costs, treatment, and insurance coverage.

What does a cruciate tear look like in a dog?
Sudden lameness on one hind leg, refusing weight or toe-touching. Partial tears cause intermittent limping, worse after exercise. Knee swelling. Your dog sits with the leg stuck out sideways. Stiffness after rest. Partial tears are easy to miss until they become complete.
How much does TPLO surgery cost?
$3,000-$6,000 per knee, including pre-op bloodwork, anesthesia, surgery, and hospitalization. Board-certified surgeons and location affect price. Add physical therapy ($500-$1,500) for optimal recovery. Both knees: $6,000-$12,000 total.
Can a dog heal from a cruciate tear without surgery?
Small dogs (under 30 lbs) may recover with strict rest, NSAIDs, physical therapy, and a knee brace, but success rates are lower and arthritis progresses faster. Dogs over 30 lbs have better outcomes with surgery. Without treatment, the knee stays unstable and meniscus damage often follows.
Will my dog tear the other cruciate ligament?
About 50% of dogs tear the other cruciate eventually - some studies show 60% within 1-2 years. The underlying degenerative process affects both knees. Healthy weight and controlled exercise reduce risk. Plan financially for possible bilateral surgery.
What is the recovery time after TPLO surgery?
Strict rest and leash walks for 2 weeks. Controlled walks increase over weeks 2-8. Physical therapy starts at 2-4 weeks. No running or jumping for 8-12 weeks. Most dogs use the leg well by 6 weeks, fully recovered by 12-16 weeks. X-rays at 8 weeks confirm bone healing.
What's the difference between TPLO and lateral suture surgery?
TPLO cuts and rotates the tibia to change knee geometry, so the knee no longer depends on the ligament. Lateral suture uses a synthetic ligament outside the joint. TPLO is the gold standard for medium to large dogs. Lateral suture works well for small dogs (under 30 lbs) and costs less ($1,500-$3,000). Your surgeon will recommend one based on your dog's size and activity.
Is my dog too old for cruciate surgery?
Age alone isn't disqualifying. Dogs 10-12+ can have successful TPLO if healthy - pre-op bloodwork and cardiac evaluation assess anesthesia risk. An older dog in pain from an unstable knee benefits a lot from surgery. Conservative management suits very old or medically compromised dogs.
Does pet insurance cover cruciate ligament surgery?
Most comprehensive policies cover cruciate surgery if you enrolled before limping. Watch for bilateral clauses - if one knee tears before enrollment, the other may be excluded. The 6-month orthopedic waiting period is a factor. At $3,000-$6,000 per knee, insurance delivers the most value.

Then came the shock. August 2026, I'm sitting on a bench outside a veterinary clinic in Brno. After his first epileptic seizure. Alf, healthy until recently, has just been diagnosed with a tumor in his belly and one in his head. I look at my own realvetcost.com, and it's one of the three most common conditions in Boxers.

I don't want to see the prognosis, but it's clear. How did it end?
