Does My Dog Need Cruciate Surgery?

RottweilerInjuries to the cranial cruciate ligament are now the most common cause of hind leg lameness in our dogs. As veterinarians, we always want to do what’s best for our patients. It’s often tough to know what is best when there isn’t enough data and reliable information to make solid recommendations. The cool thing is that there are always new studies that help us make better, more educated decisions.

For those of you that don’t know, the cranial cruciate ligament is a ligament within the knee (stifle). This provides stability to the knee and typically becomes damaged over time from run, stop turn activity.

It causes chronic discomfort until it tears completely, where we see reluctance to use the leg to any significant degree. The best treatment for a torn ACL is surgery. This is an expensive procedure and it is important to know what the benefits of surgery are.

A recent study published in the Journal of the AVMA took a look at treatment of overweight dogs treated for this injury with surgery and non-surgical treatment in addition to weight loss, physical therapy and non-steroidal anti-inflammatory drugs.

Does My Dog Need Cruciate Surgery

Overweight dogs with CCLR treated via surgical and nonsurgical methods had better outcomes than dogs treated via nonsurgical methods alone. However, almost two-thirds of the dogs in the nonsurgical treatment group had a successful outcome at the 52-week evaluation time.  Source

This study was helpful in two ways. The first was that dogs with surgery benefit significantly from other treatments in addition to the procedure itself. Overweight dogs are much more likely to tear a ligament in the knee. With post op treatment including physical therapy, weight loss and pain medication, dogs showed more improvement than with surgery alone.

The second point was that even without surgery, 2/3 of the patients showed a satisfactory outcome within a year. They, however were not as likely to improve as dogs that had surgery.

If your dog has a torn cruciate ligament, surgery with ancillary treatment is the best option. If surgery is not an option due to financial concerns, then medical management can be quite helpful in a majority of dogs.

I hope this information helps you explore all your options if your dog has a torn cranial cruciate ligament :)

    My lab was diagnosed with torn ACLs in both knees. Only 5 months old. We decided to have TPLO. We waited until 9 months per the surgeon’s suggestion — he wanted more growing before cutting. The second was about 7 weeks ago. Both knees are healing very well, but it’s been difficult to keep a puppy entertained. He’s had months of lockdown if you include activity restriction pre-op. He’s feeling so much better, but he’s still on very restricted movement. getting grumpy. It’s becoming harder and harder to keep him amused, but the end is in sight and I can’t imagine having to make any other decision — we could afford it, but who wants to? Good luck to anyone. The first week is the worst! You’ll get through it and so will your dog.

    Dr. Smith, I’m wondering if prolotherapy was part of the ancillary treatment in this study. I have a young (1 y.o) boxer/pit mix (rescue) who the vet believes at some point broke (tore) both acl’s. Additionally, it appears the growth plates in his knees never fused properly. They are recommending surgery. While I’m concerned about the cost, I don’t know how we would get through almost a year of recovery (6 mo/per knee). Prolotherapy is a relatively non-invasive treatment that has shown promise for dogs and humans. I would appreciate your input/opinion if possible.
    Thank you! Kathleen

      We have a rescue lab/shepherd mix who had this surgery done and I am thrilled with the outcome thus far. Its only been two weeks. He was a brave boy and has been hard to hold him back anxious for physical therapy to start with some hydrotherapy.
