What Is a Lateral Suture?
A lateral suture, also called extracapsular repair or lateral fabellar suture, stabilizes your dog’s knee after a torn CCL (also referred to as a crucial cruciate ligament or ACL) by placing a strong synthetic suture outside the joint. This suture mimics the function of the torn ligament and prevents the abnormal forward sliding that causes pain and instability.
The procedure works by providing immediate stabilization while scar tissue forms over the following 8-12 weeks. Once that scar tissue matures, it provides long-term support for the knee joint.

Regular rechecks are scheduled throughout the recovery to ensure a good outcome.
Frequently Asked Questions
Is lateral suture cheaper than TPLO?
Yes, lateral suture costs less because it doesn’t require bone cutting or metal implants. However, cost alone shouldn’t drive the decision. Choosing lateral suture to save money when your dog isn’t a good candidate can lead to failure and a second surgery, which costs more in the long run. The surgeon will help you understand which procedure gives your dog the best outcome.
What is the best CCL surgery for small dogs?
This varies case to case. The surgeon will assess your specific dog’s weight, activity level, and lifestyle to recommend the best option.
How long before my dog can walk after lateral suture surgery?
Your dog will walk on short, controlled leash walks starting the day after surgery—but only for bathroom breaks. Over the following 8 weeks, you’ll gradually increase walk duration as the knee heals and scar tissue forms. Most dogs return to normal walking and activity by 3-4 months. The timeline depends on following the rehab protocol carefully.
What happens if the suture fails?
Modern suture materials are very strong, and failure is uncommon in appropriate candidates
Will my dog need surgery on the other knee too?
About 30% of dogs who tear one CCL will eventually tear the other. There’s no way to prevent it, but the good news is you’ll already know what to expect.
What if I can’t afford either procedure?
CCL tears don’t heal on their own. Without surgery, most dogs develop chronic pain, and progressive lameness. We offer CareCredit financing with payment plans. Many pet insurance plans cover CCL repairs if the injury isn’t pre-existing. We’ll work with you to find a solution that gets your dog the treatment they need.
