TPLO Surgery for Dogs: What Every Pet Owner Should Know

If your dog suddenly started limping after playing in the yard, refusing to put weight on a back leg, or yelped during a seemingly normal run, there’s a good chance your veterinarian has mentioned a torn CCL — and possibly TPLO surgery. It’s one of the most common orthopedic injuries in dogs, and the terminology can feel overwhelming when you’re already worried about your pet.

Here’s what you need to know.

What Is a CCL Tear in Dogs?

The cranial cruciate ligament (CCL) is the canine equivalent of the ACL in humans. It stabilizes the knee joint (called the stifle in dogs) and prevents the tibia from sliding forward relative to the femur. When it tears — either partially or fully — the joint becomes unstable, causing pain, lameness, and eventually arthritis if left untreated.

CCL tears are the most common orthopedic injury treated by veterinary surgeons in dogs. They can happen suddenly during play or exercise, or they can develop gradually over time due to degeneration — especially in larger or more active breeds.

What Is TPLO Surgery?

TPLO stands for Tibial Plateau Leveling Osteotomy. Rather than replacing the torn ligament the way a human ACL repair might, TPLO takes a different and highly effective approach: the surgeon reshapes the top of the tibia (the tibial plateau) so that the joint can function stably without relying on the damaged ligament at all.

A curved cut is made in the bone, the tibial plateau is rotated to the correct angle, and a bone plate is secured to hold everything in position as it heals. Over time, the bone fuses and the joint becomes stable again — without the original ligament.

Why TPLO Instead of Other Options?

There are several surgical approaches to treating CCL tears in dogs. TPLO has become the gold standard for most medium to large-breed dogs because it:

• Restores long-term joint stability more reliably than older techniques
• Reduces the risk of progressive arthritis compared to non-surgical management
• Typically results in faster return to function than alternative repairs
• Has a well-established track record with high success rates

Your AVS surgeon will evaluate your dog’s size, age, activity level, and the degree of ligament damage to determine whether TPLO or another approach is the best fit.

What Does TPLO Recovery Look Like?

Recovery from TPLO surgery is gradual and structured. Most dogs follow a timeline similar to this:

• Weeks 1–2: Strict rest, pain management, and wound care. Your dog should be confined and on leash for all outdoor activity.
• Weeks 3–6: Controlled leash walks begin. Physical therapy may be recommended.
• Weeks 6–12: Gradual return to normal activity, guided by follow-up exams and X-rays.
• Months 4–6: Most dogs are back to full activity, including running and play.

Your AVS surgeon will provide detailed written discharge instructions and schedule follow-up appointments to track healing. Compliance with rest and activity restrictions during recovery is the single most important factor in a successful outcome.

Does My Dog Need TPLO Surgery?

Not every dog with a CCL injury requires surgery — very small dogs (under 15 lbs) sometimes manage well with conservative treatment. But for the vast majority of dogs, especially medium and large breeds, surgery is strongly recommended to restore quality of life and prevent long-term joint deterioration.

If your primary veterinarian has recommended a surgical consult, the next step is meeting with a board-certified veterinary surgeon at AVS. We’ll review your dog’s records, perform a full orthopedic exam, and give you a clear, honest recommendation for the best path forward.
