TPLO vs Other ACL Surgery Options for Dogs: Which Is Best?

TPLO is generally considered the most reliable surgical option for dogs of all sizes with a torn cranial cruciate ligament, offering stronger long-term joint stability than techniques like lateral suture. Comparing TPLO vs other ACL surgery options for dogs can feel overwhelming when you’re already worried about your limping companion, so our team at Brinker Veterinary Hospital breaks down exactly how these procedures differ and which dogs tend to benefit most from each.

 

 

TPLO vs Lateral Suture

Lateral suture, sometimes called extracapsular repair, is one of the oldest techniques used to stabilize a CCL-deficient knee, and it remains a reasonable option for some dogs, even as TPLO has become the more commonly recommended choice for many cases. Many veterinary surgeons performed lateral suture for decades before TPLO became widely available, and it’s still taught and practiced today, particularly for smaller patients.

How the Two Procedures Differ

Lateral suture works by placing a strong suture outside the joint to mimic the function of the torn ligament, while TPLO changes the angle of the tibia so the joint no longer depends on that ligament at all. This fundamental difference explains much of the gap in outcomes between TPLO vs lateral suture.

• Lateral suture is typically considered for smaller dogs, generally under about 20 pounds
• TPLO tends to provide more consistent, long-lasting stability in dogs
• Lateral suture is usually a less invasive, shorter procedure with a lower upfront cost, but TPLO generally shows a much lower rate of repair failure in dogs of all sizes

For small, lower-activity dogs, lateral suture can be considered. However, the TPLO vs lateral suture comparison usually favors TPLO for long-term joint function in dogs of all sizes and activity levels.

Choosing the Right Surgery

There’s no single answer to the question of which ACL surgery is “best” for every dog. The right choice depends on your dog’s size, lifestyle, the severity of the ligament tear, and your veterinarian’s clinical judgment after a thorough exam and diagnostic imaging. Rather than searching for a universal winner among TPLO and lateral suture, the more useful question is which procedure best fits your individual dog’s anatomy, activity level, and your family’s goals for their recovery.

• Ask your veterinarian why they’re recommending a specific procedure for your dog’s case
• Discuss expected recovery timelines and long-term outcomes for each option
• Consider your dog’s age, activity level, and future goals, whether that’s hiking, agility, or simply comfortable daily walks
• Factor in cost differences alongside long-term value, not just the upfront price
