Cruciate Ligament Rupture or Tear in Dogs and Cats

ACL injuries are becoming increasingly common

One of the biggest growing epidemics in small animal veterinary medicine today is the increasing diagnosis of ACL injuries, also known as anterior cruciate ligament rupture in dogs or meniscal damage of the stifles (knees) of dogs and in cats. When I graduated from veterinary school in 1991, ACL injuries were a rare diagnosis, usually only occurring in certain large breed dogs such as Rottweilers. However, today this diagnosis is rampant across all breeds and ages, costing animal guardians thousands of dollars in surgical fees to address this increasing epidemic.

While there is increasing research as to the role genetics plays in this disease, other evidence also points to an autoimmune destruction of the tissues that stabilize the stifle (or knee) joint of dogs, which means that these dogs’ own immune systems are reacting against their own tissues and bodies. While most animal guardians and even some vets feel ACL issues are traumatic in origin, genetic, hormonal (i.e low thyroid) and/or autoimmune/immune mediated causes are now considered more likely.

Again, actions like paying attention to healthy diets and avoidance of pet obesity, appropriate nutritional supplementation, as well as avoiding over vaccinating and overmedicating pets with pesticides all seem like prudent ideas in helping lessen the likelihood of illnesses like this, which in many cases are immune-mediated in response to these stressors in my opinion. While many veterinary surgeons feel early and aggressive surgical therapy with various surgical techniques offers the best options, with animals diagnosed with partial tears, often holistic therapies like physical therapy, prolotherapy, acupuncture, Chinese herbs and homeopathy can often help avoid these expensive procedures in my opinion.

As the stability of many joint diseases originate with nervous system dysfunction of the spine, chiropractic evaluation and treatment can be helpful as well. In fact, I find it quite ironic that animal guardians pay thousands of dollars to have these expensive surgeries performed on their pets (sometimes on either stifles or knees) but most surgeons acknowledge that even with surgery, these pets will develop degenerative joint disease in the future.

Using joint supplements such as glucosamine/chondroitin products like Super Joint Enhancer, fatty acids such as Super Omega 3, as well as antioxidants such as Proanthozone can all work together in helping strengthen the ligaments of the stifles. All natural white willow bark from taacan also help as natural anti-inflammatories. If necessary, veterinarians can prescribe nonsteroidal anti-inflammatory drugs such as Rimadyl, Metacam or Previcox to ease inflammation. However, it is important if your pet is on nutritional supplements, to make sure that your veterinarian is aware of what you are giving, as on occasion too many supplements and/or interactions with prescribed veterinary drugs can occur.

With time, patience and exploration of these various other modalities, many pets with at least partially torn cruciate or meniscal injuries of their stifles may be able to avoid the pain and expense of veterinary surgery.

  1. While there are many accurate statements in this post, the overall tone and thrust is misleading and partakes of a variety of alternative medicine cliches. There is no sound evidence that vaccination or parasite control has any causal connection to CCL rupture, so mentioning vaccines and “pesticides” is simply trotting out those old CAM bogemen to no purpose. Likewise, though there are immune-mediated diseases that can mimic or co-occur with CCL rupture (such as lymphoplasmacytic arthritis in Boxers), it is not approriate to identify CCL as and autoimmune or immune-mediated disease. Genetics are clearly the predominant risk factor, given the dramatic differences in incidence by breed, and body condition, neutering.

    There is no reliable evidence that homeopathy, Chinese herbs or chiropractic have any beneficial effects on the undelrying pathology of CCL disease, and while acupuncture may have some analgesic effects (or it may not, the case is open in dogs), it certainly does not eliminate the need for surgical repair. And the suggestion that spinal disease (a sneaky way of referring to the mythical vertebral subluxation) is absolutely ludicrous. GLucosamine/chondroitin have failed miserably in large-scale, well-controlled human trials to show any menaingful benefit, and the limited research evidence in dogs is not impressive.

    All-in-all, this pieces is clearly dominated by the canards and cliches of alternative medicine, which blindly advocates unproven or dispoven therapies supported by anecdote and personal experience, and blithely casts baseless shadows of suspicion on mainstream medical interventions such as vaccination and medication. Our clients expect and deserve responsible, scientific medicine from us as veterinarians, not misleading attempts to sell worthless therapies.

    I will summarize my response in a few sentences. I have 20 years of clinical experience as BOTH a conventional and holistic oriented vet and can tell you TRUTHFULLY, from REVIEWING THE LITERATURE that MOST of what we prescribe and do in every day conventional veterinary medical practice is NOT based on your criticism of holistic veterinary medicine of every day medical practice based on double blind placebo controlled studies. Most of drug use in conventional veterinary medicine is based on trial by error, “clinical experience” or extrapolation from drug use in human medicine, or using drugs like silentrol and certain nonsteroidal anti inflammatory drugs which failed safety studies in human drug trials by the same drug companies . . Hardly the safe evidence based medicine that you, on the other hand, demand that holistic veterinary medicine demonstrate. As for vaccination, according to Ron Schultz from the College of Veterinary Medicine at Wisconsin, and leading vaccine researcher in this country for decades, immunity to core viruses such as parvo/distemper lasts for LIFETIME of animal. So where is evidence/safety of giving yearly or even every three years as condoned by many vets and vet schools?……It isnt there.

    Thank you Christian for your kind comments. We do appreciate them. Certainly spread the word to your friends and family on this wonderful service and information I am happy to provide.

  4. Dr. Michael Dym, VMD veterinarianSeptember 29, 2010 at 10:53 pm

    You are very welcome. I am glad to help with this frustrating clinical syndrome of ACL rupture in dogs with supplements that can help in healing process.

  5. My own experience is that dogs with genuine cruciate disease patients respond poorly to nutraceuticals and we are ususally putting off the inevitable. I’m all for medical management if possible but it has not been my experience. certainly, partial tears an be difficult to diagnose and arthroscopy is usually required to confirm. Thes patients can make an excellent and rapid response to surgeries such as TPLO.

    best wishes

    Hi Andrew: You are indeed correct about diagnosis and surgical treatment. However in today’s economy many clients cant afford surgery and in the trenches I have seen many pets with partial tears respond fine to rest and anti inflammatories and nutraceuticals. Yes they are more prone to arthritis down the road, but then even surgically treated dogs sometimes develop arthritis as well in these joints. I find many pets with partial tears do returrn to function in many cases but you are correct about ideal treatment.

  7. Our cattle dog was just diagnosed with a ccl tear and we are considering prolotherapy..what is your opinion? Also what are the effects if it is a complete tear vs. a partial tear, and are there any contraindications if there is no tear? He is currently taking prevacox and will need to stop that and start tylenol if we decide to go ahead with the therapy. Cowboy has been taking DS cosaquin for nearly a year now as we thought the lameness came from his hip. This is not our regular vet who will do the therapy, and I am also going to ask her thoughts on the subject as well. His visit with an ortho recommended surgery…the long recovery had me shaken as he is an active dog, more correctly, he wants to be but can’t be now. Thankfully he’s still a happy fellow. Thank you for any information you can share.

  8. Dr. Michael Dym, VMD veterinarianOctober 19, 2010 at 3:09 pm

    I am not an expert in prolotherapy being only somewhat familiar with it. I dont think there would be any contraindications if there is no tear if prolotherapy done, as harmless injections into and around joint to promote healing from my understanding.

  9. My dog Ollie was diagnosed with a ruptured cranial cruciate ligament today. He hurt his leg yesterday playing in the snow. Our doctor (who we do not have a relationship with because we just moved) diagnosed Ollie very quickly and said surgery is his best option because he is only 5 and he could handle it. She gave me a quote of $3100.00 and told me I should schedule surgery within a month because it is possible the other leg will go and they won’t do surgery if both of them have been ruptured. I have been reading as much as I can on this and I have heard pros and cons to the surgery and also pros and cons to a natural treatment. So my question is, would it hurt to give Ollie the opportunity to try to recover on his own before making the choice to do the surgery? Lauren

  10. Dr. Michael Dym, VMD veterinarianFebruary 14, 2011 at 7:55 pm

    Ideally surgery is the best choice as early correction of this condition lessens the amount of future arthritis and degenerative joint disease. However in my experience and opinion, I have seen some dogs, particularly small dogs respond well to rest and anti inflammatory and supplement therapy. Many pets will regain function over time, however there is an increased liklihood of more severe joint disease down the road. I would give it 4-6 weeks of rest and supportive care and see if any positive change. If not then you can always go for surgery. Also may help to get second opinion from vet in your area, preferably a veterinary surgeon.

  11. Hi, my 85 lb lab tore his ACL 6 weeks ago. Our local vet said to rest him up and see how he does. He actually got to the point where he had no noticable limp, doing VERY well on conservative Management. Then 3-4 weeks into Cm we had an “opps” moment with him and another one of our dogs. he could not put any weight on leg. He saw another vet(ortho surgeon) who of course said he needed surgery.(TTA) We are still doing CM while i continue to research and he is doing much better, weight on leg sometimes.I have decided if we do surgery i wont do TTA, will go with the old school fishing line traditional. I just can’t get around the breaking bone to repair ligament if there is an alternative. He has been on a great glucosamine supp(syn-flex) fish oil, vic c, msm, hyrolanic acid, homecooked diet to monitor his weight which has gone up due to confinement. How long can and should i continue with CM (if good results contine) before i decide to go with surgery? I hate to go 6 months on CM then end up having to do surgery anyways and then we have 6-12 restricted activity. My understanding is arthritis will occur wether i have surgery or not. I am also getting him the A Trak Brace which i have heard great success with (most who didn’t like it had a problem with fit and the company has a crappy return policy) any thoughts?

  12. Dr. Michael Dym, VMD veterinarianApril 10, 2011 at 8:43 pm

    I would usually give CM 4-6 months. If no improvement by then then surgery would be needed. ..Also consider yucca intensive by azmira from 1800petmeds as well as myristin and myristaid by EHP products.

  13. i have a 14 ( almost 15 year old cattle dog) She is a warrior and seems to overcome every \mis-diagnoses throughout her years…She has the energy of a 9 or 10 year old. She tore her ACL on Tuesday, I got an xray on Thursday and I am a mess trying to figure out if she shoud have surgery. She is the tyoe of dog who was siagnosed with a possible nose tumor and after giving her Yunnan Biayo after a month or so her nose is back to normal. My vet is \mystified\ was what he said and she’s back to her healthy, happy, normal 14 year old self. And now this ACL.. She is my life. I sruggle finalcially- but would somehow make it work with a payment plan for surgery. I am having a really tough time making a decision. Will she get though the surgery//? Is it better to do the surgery and not have the greater chance of forming arthritis. The ortho surgeon said she has very clean bones, no tumors in legs or arthritis when he took the xray… which makes this even more difficult. Anyway.. if there is anything you can offer in regards to this.. I am a mess. would do anything for her.. but just dont want her to be in pain and want to to the \right\ thing..
    thank you, in advance for your advise…

    You could try working with a homeopathic vet. To learn more see my website http://www.canineworld.com/drdym. I would consider supplements to start such as super joint enhancer from 1800petmeds as well as possibly yucca intensive. I have seen many dogs with partial tears regain use of limb function over time with rest and more holistic care.

  15. My mom is in the hospital and her pomeranian had one bad leg now it seems like both legs are bad and its hips are bad. He is 12 yrs old and he is talking benazepril for his heart. He was coughing a few months ago and we got the pill for his cough as needed and the benazepril daily. At this point I was wondering if a hip acl type brace might be helpful for his last year or so left most likely all that is left. I had to hold his rear quarters up after slipping trying to poop and he couldn’t get back up….I’m feeling really bad for the little guy, were going to the vet tomorrow.

  16. Dr. Michael Dym, VMD veterinarianSeptember 9, 2012 at 3:28 pm

    Hip braces will likely not help. I would consider joint supplements like glyoflex II From 1800petmeds and perhaps yucca intensive. A fatty acid supplement like missing link might help as well.

  17. Ollive all of a sudden some time ago did not want to walk and some times that got better, We have had to the Vet and they know she has allergies, but we had not discussed her not waning to walk. Now she seems better and then the itching started. We are stumped. Please send me information onm my e mail

  18. My 53 pound, almost 10 year old, Border Collie has two torn ACL’s and it is breaking my heart. We have started him on Glycoflex 3, Fish oil, and Proanthozone 50. He was looking so much better and then after a day of minimal romping he digressed. We felt like surgery would be too much at his age . . . do you think leg braces would help?

  19. A brace may or may not help. You could also consider working with a holistic veterinarian in your area i.e http://www.theAVH.org You may want to consider laser as well as other forms of holistic support i.e water/hydro therapy, acupuncture, etc

  20. My little girl Monet..Is so dear to me I don’t think I could go on without her …….

    She The same problem..I try real hard to alleviate any pain she may have..
    She is a mix of Shih-tzu and Maltese….Now eight years old…..

    I give her Rimadyl for pain..When I know she is in pain..Also 50 mg. Of fish oil once every day….It has made a great difference in her gate,,,

    She has a home cooked diet with all the nessacary vitamins and nutrients…
    I am grateful to be able to have a little family member to give me so much enjoyment in my life..

  21. HI Adeline. IT does sound like you love your canine companion very much. PRoper, home cooked meals can offer the best foundation of nutrition and good health, because as Hippocrates, the father of medicine once said, “Let food be thy medicine” Just make sure you are following balanced recipes. See book Dr Pitcairn’s Guide To Natural Health For Dogs and Cats By Richard PItcairn, DVM, phd for more detailed discussion. Also consider glucosamine/MSM supplement, such as Glycoflex from 1800petmeds, as well as antioxidant supplementation such as proanthozone as well.
