We call this the everything guide to dog ACL injuries because what you are about to read, see, and links included represent years of actual experience with this issue times two and a variety of treatment modalities with eventual surgeries.
I know all too well about canine knee injuries: In the past two years, my dog has ruptured both ACLs (anterior cruciate ligaments) in his legs. After trying conservative management, including a custom orthotic knee brace, cold laser therapy, limited mobility aka rest, and anti-inflammmatories, surgery was still required: Times two.
My dog, Dexter, had ACL surgery utilizing extracapsular suture technique on his left leg in 2013 and on his right leg in 2014 . There is a high likelihood that if a dog tears an ACL, the other leg will be affected within one to years following. It sucks, I know.
If you’ve arrived at this article it is likely that your dog:
- Tore his or her ACL and you are looking for options other than surgery;
- You are curious and never heard of an ACL brace for dogs;
The ACL (aka CCL) is a ligament that is commonly damaged. In fact, the surgeon who performed the two surgeries on my dog says that more than half of his patients have this injury. In fact, some dogs are more prone to ACL injury than others. However, ANY dog at any age of any breed, lineage, or mutt can tear an ACL.
Living With an ACL Tear
If I had to do it all over again, I would still try the conservative approach first since on his first injury, as my dog’s first ACL tear was partial. I am glad I tried, but I now know that most partial ACL tears progress to full. A partial tear of the anterior cruciate ligament is a diagnosis a lot of dog parents receive. This means that the entire ligament is not torn and has not yet fully ruptured.
It is likely, but not certain, that the ligament will progress to a full tear. I have encountered dog moms and dads who tell me their dog lives comfortably with a partial tear of the ACL. Any joint that is compromised is prone to develop arthritis. Living with a partial tear does have limitations: At any time, it can progress to a full tear and then surgery is most likely required. Scar tissue can take the place of the damaged ligament, but it will come at a cost: Arthritis, pain, and/or limited mobility.
For Dogs Who Can’t Have Surgery
Not all dogs are surgical candidates for a variety of reasons: Cost of surgery, other health conditions, age and risk of anesthesia, etc. In addition, there are many types of ACL repairs. Smaller dogs tend to have an extracapsular repair done while bigger dogs with bigger bones may require TPLO surgery.
For dogs who are not undergoing surgery for one reason or another, stabilizing the knee is of utmost importance. ACL tears that are not treated at all are at very high risk for developing degenerative arthritis. Imagine the ligament is a rubber band. If you snap that rubber band in half, the knee can no longer keep stable.
Like humans, dogs routinely injure the anterior or Cranial Cruciate Ligament (CCL aka ACL) in their knees. Since the CCL prevents subluxation of the knee joint, maintaining its integrity is of primary concern. Since ligaments connect bones, when a tear in the ligament occurs, the stability is no longer there. A stable knee means a stable joint and scar tissue can then take the place of the tear. Ligaments cannot regenerate themselves, so scar tissue formation is crucial. Here’s a good piece from Colorado State University Veterinary Teaching Hospital about ACL tears and repairs.
Braces for Dogs
An ACL tear takes months to heal and many more months before dog parents should engage the dog in their normal activities so as to not have a recurrence or re-injury. During that time, you want scar tissue to form for the reasons noted above. In order for scar tissue to replace the torn area, the knee joint must be stable. Stability comes with: Rest or a stabilizing device, such as a brace.
Yes, they make braces for dogs. Not all products are created equal, and this holds true when it comes to products designed to create comfort and stabilize the knee when a dog has an ACL tear or rupture.
I discovered a small business within driving distance of my home called My Pet’s Brace. They provide orthotic devices for dogs that require bracing to support hip, stifle, hock and paw injuries in the hind legs and shoulder, elbow and carpal injuries in the front legs.
Much of their primary clientele in dogs deals with ligament ruptures and tears. After a thorough examination and assessing Dexter’s somewhat limpy gait, a stifle brace was recommended. The brace would be worn for 6 to 9 months during “active waking hours,” which for a then 4-year-old Cocker Spaniel is quite often. The brace cost $625 for a dog of Dexter’s size, which is a worthwhile investment. If surgery is necessary, ranges average between $1,800 and $2,500 (or more) – depending on where you live and nature of the operation required.
Incidentally, in the thousands of operations the orthopedic surgeon performs locally each year, I was the first person ever to have a dog try the custom brace. He even asked me to bring the brace in and show him, which he in turn, showed his colleagues.
Not All Braces Are Created Equal
I have since learned that not all braces are created equal. A custom brace is most effective because, like a custom brace for a person, it conforms to the exact specifications of your dog’s anatomy. Not all knees, legs or dogs are the size same and with the same structures. Two Cocker Spaniels, for example, side by side, still do not have the same anatomical measurements.
There are a variety of non-custom braces available, but none could guarantee the precise custom molding to my dog’s knee as that from a facility that makes them with your dog’s specifications in mind.
The folks at the orthotic center actually casted my dog’s leg and the brace was built from that. It is important to understand the process that goes into crafting a custom device for your dog versus purchasing one that is designed for most any dog to wear. I realize there are cheaper options available, but I wanted the security and peace of mind that my dog’s anatomy and healing would be best served by a device actually designed for him, with precision accuracy and a staff willing to help me before, during, and after…plus followup appointments.
Custom Knee Brace Step by Step
The four steps in the simple process of creating a custom device for your pet are: 1) taking a cast of the leg or other body part, 2) fabricating or building the device, 3) fitting the device on the dog and, 4) modifications and adjustments, if necessary. (Steps 3 and 4 are usually accomplished at the same time.)
It sounds more complicated than it actually is, so here’s a visual and video guide of what happens, and in our case, for a custom stifle joint for ACL stability:
You and your dog’s veterinarian discuss options and if it is determined that a leg brace would best serve your dog, find a brace business that actually can see and touch your dog for custom molding. If there is not a clinic near you to do this, many times a kit is sent to the veterinarian and they perform the casting, then return it for custom molding to the orthotic manufacturers.
We opted to drive to the facility for the process. After meeting with the folks at My Pet’s Brace, the process began. My biggest concerns were pain during the process and if my dog would adjust to the end product. There was no pain, the process was easy, and Dexter adjusted to the brace in about 60 seconds. It takes most dogs a day or so (or less) to adjust, so we were very fortunate.
The entire process took about five minutes to actually take an exact replica of Dexter’s stifle area. This is best left up to the experts, and the business we dealt with works with veterinarians all over the country. They send the kit to your vet’s office, your vet can do the casting and then send it back to them for custom creation. Spending the time necessary to take a good cast in the proper final alignment is critical in obtaining a well-fitting functional device.
Here are some images of the actual process that occurs once the client leaves and the casting begins:
From moulding to casting to sizing, many steps occur to make a custom orthotic stifle for a dog.
My dog wore the brace for 90 days, except for sleeping or while lounging around in the house. Though the brace did help to stabilize the knee, his light running with it on did more to put stress on the already fragile ACL and snap, one day it just gave out. Once the ACL fully ruptured, this meant bone on bone contact. You can read about the first ACL surgery with pictures and more here. At this point, surgery was required and we’ve outlined the entire process below.
In June of 2013, Dexter’s ACL in the other leg tore from a simple running movement at the park, just as the experts predict may happen. The same doctor, same surgery, and same recovery process ensued.
The costs vary from vet to vet, surgeon to surgeon, and city to city. Here’s a breakdown of some of the costs we incurred:
Custom orthotic brace for left stifle: $625
Six cold laser therapy treatments: $250
Extracapsular surgery with same-day release from veterinary hospital: $2,000
My dog’s love and devotion coupled with good health: Priceless.
I should note that we have had Veterinary Pet Insurance (now Nationwide) for about 20 years and we have had nothing but success with them on the Major Medical Plan with additional coverage. About 90 percent of all of the above was covered under our policy, which has a very reasonable cost per month.
Having an ACL injury can be tricky, for both the dog and the pet parent who must restrict activity without creating a withdrawn dog who has no clue why he or she is not allowed to run and pla. However, there are options available and the links below will guide you through. If your dog has suffered an ACL injury, let us know your experiences, too.
