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 lameness, joint instability, 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 lameness or limping on a hind leg. Leg extended to the side when sitting. Stiffness after rest. Knee swelling. Clicking when walking. Reluctance to jump, run, or climb stairs. Weight shifts to front legs. Can be sudden or gradual onset.
Diagnosis $200-$500
Treatment $3,000-$6,000/knee
TPLO (tibial plateau leveling osteotomy) is 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. Plus 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 significantly improves outcomes.
Prevention
Maintain healthy weight. Avoid sudden stops and sharp turns on slippery surfaces. Regular exercise to strengthen 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 enrolled before limping. 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 delivers maximum insurance 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 period is less problematic than 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. Dog sits with leg extended 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, eliminating cruciate dependence. Lateral suture uses a synthetic ligament outside the joint. TPLO is gold standard for medium to large dogs. Lateral suture works well for small dogs (under 30 lbs) and costs less ($1,500-$3,000). Surgeon recommends based on 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 significantly 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 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 maximum value.
My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
