Hello! In June my 7 year old English Bulldog, Kata, was running on her walk when she seemed to step wrong or something. She continued to run and play, not seeming to be bothered much. I assumed it was just a pulled muscle or something.

Then last week we had her off leash and she took off after a cat. She came home limping and would not put any weight on her left rear leg. I took her to the vet a few days later and the vet thinks it is a cruciate ligament injury. The vet did not do x-rays (as she knew if we decided on surgery the surgeon she referred me to would want to do her own) so I do not know the extent of the injury.

She is currently on Rimadyl (only a week’s supply as of now) and is putting weight on the leg, but not a lot. I can tell it is uncomfortable for her to squat when going to the bathroom. Overall she is pretty mellow, only trying to jump and “trot” when someone comes home. We have not been walking her and she is devastated since right now it is finally starting to cool off (we live in AZ). I am so torn as to what is the best choice for a 7, almost 8, year old bully who still seems full of life and not in much pain.

I want her to be able to run and play though, but don’t want to put her through a painful surgery and recovery if she can recover with just CM.

How to tell? I know that there is no rush to make a decision, however, I feel like the more time that passes the older she gets and more risk comes with age for surgery. HELP!

Conservative Management Advice for CCL Injury – Kata is a post from: Dog Knee Surgery and Ligament Injuries

Help!  My dog is limping – Could it be a torn ligament?

This guide is a good starting place for anyone looking for more information on dog knee problems, specifically cruciate ligament injury in dogs.  This article will give an overview of dog knee injuries covering everything from symptoms to recovery.

What is a Cruciate Ligament Injury?

An injury to the CCL (also known as the cranial cruciate ligament and sometimes called the ACL) can cause lameness in dogs, and is one of the most common causes of rear leg lameness. The function of the cruciate ligament in dogs is to stop the femur (large bone at the top of the leg, above knee) and tibia (smaller bone at bottom of leg, below knee) from rubbing against one another. When the cranial cruciate ligament is torn or ruptured the leg loses stability because these bones are now free to move back and forth on top of one another, causing friction, inflammation, possible meniscal injury and eventually arthritis.

During activities with a healthy dog ACL ligament there will be tension on the ligament, preventing the femur from pressing into the tibia, creating a sliding motion for fluid movement. If your dog is walking or running with a cruciate ligament tear there will be no tension on the CCL, allowing the bones to unnaturally move together, causing pain, lameness and an aversion to using the leg. The best way to think of this would be to envision the ligament like a rubber band, but instead of holding the bones together, the rubber band is in place to prevent the bones from coming into contact. When the rubber band is snapped, there is no longer a gliding joint in the knee and there is contact between the bones.

Acute vs. Chronic Causes of Cruciate Ligament Injury

Acute injury is generally associated with trauma. If the CCL (also referred to as ACL because of it’s similar function to the human ACL) is injured acutely it will most often be due to improper rotation of the knee and hyper extension. This can occur in many different ways such as a dog taking a misstep off a curb, stepping into a divot, jumping or becoming stuck, using a jerking motion to free him/herself.

Chronic injury of the canine ACL is generally associated with disease, age related degenerative changes of the ligament, excess weight (obesity) and conformation of the knee joint (certain large breed dogs are more prone to these types of injuries due to the way their back legs are formed). In the case of chronic injury of the cruciate ligament, there is very little that can be done to prevent the injury from taking place.

Size Matters

Small and large dogs fair differently with the same type of ACL injury. Studies have shown that dogs weighing less than about 25 pounds can experience a full recovery from ligament damage without surgery. This is not true in dogs above the 25 pound threshold. While dogs over 25 pounds may appear to be improving with conservative methods, these larger dogs rarely return to their full function without any issue. This is not to say that there has never been a case of a medium to large sized dog recovering from a torn CCL with only conservative management, but does demonstrate that smaller dogs have an easier time fully recovering using the conservative approaches.

Symtoms of a torn, ruptured or injured CCL will vary from dog to dog, and depending on whether the injury was acute or chronic in nature. Some dogs with a fully torn cruciate may only exhibit mild lameness, while others with a tear may not bear any weight on the leg at all. This again varies based on the type of dog, their size and whether other structures within the knee (particularly the meniscus) were also damaged. Below are some of the most common symptoms associated with a dog knee ligament injury.

Symptoms of a Dog ACL Tear:

1. Decreased range of motion.
2. Hind leg extended straight when sitting down (this is known as the sit sign).
3. Crackling noise of bones rubbing against each other – the medical term for this is Crepitus.
4. Dog exhibits signs of pain when knee (stifle) joint is touched.
5. Exercise intolerance.
6. Limited range of motion or mobility.
7. Stiffness, limping or unwillingness to use the leg after exercise.
8. Knee joint is swollen and/or hot to the touch.
9. Thick, tight, hard and/or firm feel to knee.
10. When standing will only place weight on the toe instead of using entire foot (called toe-touching). An early sign of toe-touching is to only have weight on one side of the body when standing.

There are other conditions with symptoms similar to a dog ACL injury such as: arthritis, knee sprain, meniscal injury, hip dysplasia, patellar fracture, patellar luxation, myelopathies, lyme disease and others. Please schedule an appointment with your vet if your dog shows any of the CCL tear symptoms listed above.

What if my dog’s CCL is never repaired?

This, again, depends on their size, breed and a number of other factors. Some dogs without a CCL may do just fine, while others may use the ability to use their leg. One truth for any dog without a supporting knee ligament is the fact that they will be more succeptible to injuring other structures within the knee, particularly the meniscus. The role of the mensicus in the knee is to act as a cushion, and absorb shocks. Damage to the meniscus is serious and typically leads to arthritic change and lameness.

What to Expect During Your First Veterinary Visit for a Suspected CCL Injury

Consultation and Review of Symptoms

Your veterinarian will review your dog’s symptoms and time of onset.  Going through a detailed history will allow your vet to determine if conditions with similar symptoms may be ruled out at this time.

Physical Exam

Walking Gait

Your veterinarian will want to watch your dog walk and run to see how they are balancing their weight and using the affected leg.

Palpation of the Joint

Your veterinarian will touch your dog’s knee to assess the joint looking for signs of:

• Swelling or Inflammation
• Loss of Muscle Tone
• Pain or Soreness
• Range of Motion
• Popping of the Joint
• Fluid Accumulation

Drawer Sign Test

During the drawer test the veterinarian with stabilize your dog’s femur with one hand while manipulating the tibia with the other. If the tibia moves forward, known as a positive drawer because of the way the bone moves similar to a drawer being opened, the ligament is ruptured.   A negative drawer sign does not necessarily mean your canine does not have a cranial cruciate injury, and false negatives can happen if your pet is tense, if the injury is old and if there is arthritis.

Tibial Compression Exam

Another test, similar to the eliciting the drawer sign, is the tibial compression test. During this exam your veterinary physician will stabilize the dog’s femur with one hand, while flexing the ankle with the other. In dogs with a ruptured cranial cruciate ligament, the tibia will display forward motion upon flexion of the ankle joint.  Again, a negative tibial compression exam does not rule out a cruciate ligament injury, and many factors can contribute to a false negative result.

How to Test a Dog for a Knee Ligament Injury

X-Rays for CCL Injuries

Radiographs are usually taken, not to diagnose a cruciate ligament injury (soft tissue damage is not clearly visible on x-ray), but to rule out other diseases such as cancer and hip dysplasia. An xray will confirm the presence of fluid in the joint as well as arthritis, which will help to confirm the diagnosis of a cruciate ligament injury.

Ultrasound for CCL Injuries

Ultrasound may be used to positively diagnose a CCL injury. Unfortunately a minority of medical clinics are equipped to do ultrasound, and many veterinarians rely on the results of the consultation with you, physical exam and ruling out any other conditions by x-ray to make the diagnosis of a CCL injury.

My Dog Has Received a Positive Diagnosis of a CCL Injury – What Are My Treatment Options?

There are two major avenues for treating a dog knee ligament injury – conservative management or dog knee surgery.

What Is Conservative Management?

Conservative management is a non-surgical option for treating cranial cruciate ligament (CCL) injuries in dogs. Depending on the size of your dog, the severity of the injury, presence of other damage (particularly to the meniscus – remember, this is the part of the knee that acts as a shock absorber) and the duration of time since the onset CM may be a good option for your dog. As mentioned above, dogs weighing less than 25 pounds tend to have better outcomes using conservative techniques than larger dogs.

A variety of techniques can be used if you choose Conservative Management (CM) for your pet.

Conservative Management Includes:

“Standard” Conservative Management

• Rest – Your dog should remain inactive during the recovery period, abstaining from rough play, prolonged exercise or any movement that may cause any pressure or unwanted movement within the knee joint.
• Weight Control (and reduction if necessary) – One way to reduce stress on the joint is to keep your dog’s weight under control, and if possible, underweight is better during the recovery process.
• Anti Inflammatory Medications – There are a number of Holistic (ex – Yucca Root) and Prescription (ex – Rimadyl) medications available that can help to make your pet more comfortable as the knee heals.

“Optional” Conservative Management

• Dog Knee Brace – There are a variety of dog knee braces available including the orthopets canine stifle brace and atrac dynamic brace.
• Veterinary Acupuncture – Acupuncture for dogs is available, and can help to de-stress your pet as their body heals.
• Veterinary Chiropractic - A chiropractor can work with your dog to make sure your pet is free from any subluxations or other blockages.
• Physical Therapy for Dogs – Working with a certified canine physical therapist can help to ensure your dog maintains muscle tone and range of motion in the leg following their injury.

What Are The Different Types of Surgery for Dog ACL Injuries?

Dog Knee Surgery Options:

TPLO Surgery (tibial plateau leveling osteotomy)

This surgery adjusts the slope of the tibial plateau (preventing unwanted forward motion) by cutting and rotating the top of the tibia, and keeping it in position with a bone plate (which can be removed after healing).

TTA Surgery (tibial tuberosity advancement)

The TTA surgery also focuses on changing the angles of the bones within the knee joint. In a TTA the tibia is cut and moved forward to create stability. The new position of the bone is held into place with a bone plate (which can be removed after healing).

TTO Surgery (triple tibial osteotomy)

The TTO is a combintation of the TPLO and TTA techniques. It moves the tibial crest forward, as a TTA does, and also adjusts the tibial plateau to 90 degrees, as the TPLO does.

Tightrope Surgery

Tightrope CCL is an extra capsular technique using the lateral suture stabilization (LSS) procedure in conjunction with a material called FiberTape to provide bone to bone stabilization.

Extra Capsular Suture (traditional repair, extracapsular imbrication)

This is referred to as a traditional repair because this was once the conventional treatment for CCL tears. The extra capsular suture uses a strong leader line suture in a figure eight pattern around the knee to provide stability and keep the knee in a normal position.

Fibular Head Transposition (fibular head transfer)

The fibular head transfer surgery utilizes another ligament in the knee, the lateral collateral ligament, to take the place of the CCL. In this surgery the fibula is rotated so that the lateral collateral ligament can perform the function of the CCL.

Dog CCL Surgery Recovery

Depending on where the ligament surgery was performed, your dog may stay overnight to be monitored and receive pain medications following the procedure. TPLO surgery recovery can be different from TTA surgery recovery, so it’s important to follow the recommendations of your vet during the post operative period. Your dog’s sutures will be removed within a week or two of the procedure, and follow up appointments are typically done at 2 weeks, 4 weeks, 8 weeks and 12 weeks. Again, depending on the type of surgery done, radiographs may be done during these follow up appointments.

During the 6-14 week period following surgery it is very important to severely limit your pet’s activities. For approximately three months following dog knee ligament surgery your pet should be confined to a crate, small room or enclosed area when you are not able to be with your pet. You will probably want to make use of a dog cone collar – Elizabethan collars or Pro collars are my favorite. Make sure to post operative doggy proof your house and make sure they have no opportunity to slip, slide, jump up onto furniture, climb up stairs or engage in any activity that may damage the healing knee.

While outside you should accompany your dog for bathroom breaks, and they should always be controlled on a leash – you never know when a post operative dog may get the urge to chase a squirrel! You may increase the length of walks during the recovery period under the recommendation of your veterinarian and judging by how well your dog is recovering. I strongly recommend not letting your dog off leash at all during the first few months following surgery just to be on the safe side. Your veterinarian will most likely encourage you to have your pet use the injured limb immediately following surgery, but do not overdo it. Physical therapy during this time can also be very beneficial, and swimming is a great way to ensure your dog gets to use their leg (helping to maintain strength and muscle mass) without engaging in any activities that may be harmful to the knee.

Cruciate Ligament Injury in Dogs is a post from: Dog Knee Surgery and Ligament Injuries

How much will a TPLO surgery for my dog cost?  How much should I expect to spend on a TPLO repair?

TPLO, also known as Tibial Plateau Leveling Osteotomy, is a CCL repair technique through which the veterinary surgeon alters the head of the tibia and plates it to create a new joint angle.  Simply put – your veterinarian will re-invent your dog’s injured knee joint to provide increased stability through changing the way the top and bottom of the leg meet at the knee joint.  This is the most invasive, and requires the most surgical skill, of all the surgical cranial cruciate ligament repair options; it is also the most expensive.  In this article we will break down an actual TPLO cost estimate and explore the cost of choosing this type of CCL repair surgery for your dog.

Below is the estimate I received for my dog to undergo TPLO surgery. 

A few things to note before going into the details of the invoice:

1)  My dog in an American Bulldog weighing roughly 90 pounds (normal weight), and is 5 years old.

2)  He is in good health with no pre-existing conditions that would complicate anesthesia or surgery.

3)  This estimate, although some of the information has been blacked out to protect privacy, is from a speciality veterinary clinic with veterinary surgeons who specialize in cranial cruciate ligament repair surgeries in dogs.

4)  I live in Southern California, and this estimate is from a veterinary office in that area.

Here is the estimate I received for a TPLO CCL repair.  The low end of the estimate was $3,892.79 and the high end of the estimate was $4,03.58 for TPLO surgery.

I will go line by line to go over the charges included in the cost of TPLO surgery.  For smaller animals some of the values will be less, and accordingly for larger dogs.  Hopefully this invoice will give you a basic picture of what you can expect to pay for a TPLO, and where all of the money goes.

EST TPLO Surgery Med/Large – $0 – Just tells us what type of estimate we are looking at.

CBC and Chemistry Profile – $163.80 – Basic blood panel the veterinarian will want to run prior to surgery to determine if you dog is fit to be put under anesthesia and to rule out any other complications.  One way we could have saved money here was to have our dog’s regular vet perform this blood panel at a lower price than to have it done at the speciality clinic.

Radiograph, 2 Views – $224.70 – This is the x-rays that need to be performed prior to the TPLO so the surgeon is able to properly manipulate the tibia during surgery to create the desired angles.  These will need to be performed somewhere prior to TPLO, and some veterinarians will want to do the xrays themselves.

Radiology Interpretation – $45.68 – Fee charged for processing and reading the x-ray.

Catheterization, Intravenous – $94.00 – This fee is for the placement and maintainence of an IV catheter while your dog is undergoing and recovering from TPLO surgery.  Your dog will be given IV fluids and possibly medications through this catheter during the duration of surgery and post operative hospitalization.

Epidural Injection – $86.52 – Local anesthetic (pain relieving medication) will be injected into the lumbosacral (in the spine) space of your dog prior to surgery.  Depending on what types of medication(s) your veterinarian uses this can help to alleviate pain after surgery, and desensitize the effected site during surgery.

Surgery Room Use – $113.82 – Fee for using the Operating Room space to perform the TPLO.

TPLO Inhalant Anesthesia – $306.34 – Cost of putting your dog under gas anesthesia for the time required to perform the TPLO procedure.  This is used in conjunction with the epidural anesthesia.

Surgical Anesthesia Level 1 – $294.00 – Fee for dog to be put under anesthesia and monitored during TPLO surgery.

Surgical Supplies, Orthopedic – $358.05 – Cost for instruments to be used during surgery; this does not include the cost of the actual TPLO implant.

TPLO Surgical Implants, Med/Large – $358.05 – Cost of TPLO implant plates to be placed on the bone during surgery.

TPLO Surgeons Fee – $974.40 – Price veterinary surgeon charges to perform TPLO operation.

Radiograph, Post Op – $192.52 – Cost of x-ray to be taken following surgery to check placement of implant and knee joint angles.

Elective Ortho Hospitalization, General – $138.92 – Cost of overnight hospital stay following TPLO repair surgery.

Fluids – IV, Inital 24 Hours – $0-$190.31 – This would depend on whether or not your dog was being cared for at the hospital post operatively, and how much fluids your pet required.

Misc. Medications, Orthopedic - $450 – This includes prescription medications given to your pet post operatively and those sent home with you during the post operative period.  They would include a sedative (Acepromazine), pain relief (Tramadol), anti inflammatory (Rimadyl), and an antibiotic(Cephalexin), and possibly other medications at your veterinarian’s discretion.

Fentanyl, 75 mcg patch – $65 – Pain relief patch that will be placed in your pet to control post operative discomfort.

Buster Collar, Clear – $25.26 – Collar to be placed on your dog during the post operative period to prevent them from ripping out their stitches or injuring the surgical site.

Included:  X-ray at 8 weeks to check the post operative recovery and  misc. sedative (not sure if this is sedative used during the surgery itself or the sedative medication to take home with you following TPLO surgery).

Also included are all of the post operative recheck visits, but be aware that if you pet develops any complications related to the surgery you will be required to pay for any additional expenses incurred.

What is the Actual Cost of TPLO Surgery? is a post from: Dog Knee Surgery and Ligament Injuries

The mechanism for cruciate ligament degeneration prior to rupturing is not clearly understood, but it is clear that certain factors predispose certain dogs to sustaining a cranial cruciate ligament injury. Certain breeds, such as Labradors and Rottweilers (and other large breed dogs), are much more commonly affected than others, as well as dogs that are overweight. This suggests there is an inherited component to the condition, possibly related to conformation or gait and/or the displacement of weight within the stifle (knee) joint. While there is nothing that can be done to prevent CCL injury, by recognizing the symptoms of CCL damage soon after onset you can give your dog a head start with recovery.

What Causes the CCL to Rupture? is a post from: Dog Knee Surgery and Ligament Injuries

If it is suspected that your dog has a cranial cruciate ligament tear or rupture, your veterinarian will perform a physical exam to determine whether or not this type of injury can be ruled out. This test involves manual manipulation of the knee joint and is referred to as the drawer test. Most dogs do not need to be sedated to complete this exam, but you will need to be the judge in determining whether or not this is necessary – if your dog’s joint is particularly painful or they do not have a great track record for excellent behavior at the vet, you may want to consider giving them sedation in order to complete the exam. A normal stifle will not exhibit a positive drawer sign, making a positive drawer an absolute indicator for CCL damage.

During the drawer test the veterinarian with stabilize your dog’s femur with one hand while manipulating the tibia with the other. If the tibia moves forward, known as a positive drawer because of the way the bone moves similar to a drawer being opened, the ligament is ruptured. If the rupture occurred some time ago, there will be swelling on the side of the leg that faces the other leg – this phenomenon is known as a medial buttress and is indicative of arthritis. The presence of a medial buttress, coupled with your dog’s state – if they are anxious or tense – can make it difficult to obtain an accurate drawer sign. Tense muscles can act as false stabilization of the knee, preventing demonstration of the drawer sign upon manipulation; sedation is indicated in these cases.

Your pet’s doctor will take the results from the drawer sign test into consideration when determining a treatment plan for your dog. A negative drawer sign does not necessarily mean your canine does not have a cranial cruciate injury, and the only way to be absolutely sure of injury in the absence of a positive drawer is to have an ultrasound performed; unfortunately not many vets offer this service.

No two dogs are alike when it comes to knee injuries. Some dogs will display many of the knee injury symptoms listed below, while others will only have intermittent lameness. Lameness in canines can have many causes, some of which are not directly leg related, and it is important for your dog to be evaluated by a veterinarian for any cases of unexplained lameness in any limb. Examining the way in which your dog was injured, if it can be determined, will play an important role in diagnosing a possible canine cruciate ligament tear or rupture. Careful evaluation of the symptoms, along with any diagnostic testing done by your pet’s doctor, will determine whether conservative management or surgery is indicated.

Canine Cruicate (Knee) Injury Symptoms:

1. Decreased range of motion.
2. Hind leg extended when sitting – this is known as the sit sign.
3. Crepitus – crackling noise of bones rubbing against each other.
4. Pain – when stifle (knee) joint is touched.
5. Unwilling or resistant to exercise.
6. Restricted mobility or extension.
7. Stiffness after exercise.
8. Swelling of joint.
9. Thick, firm feel to knee are, may be hot to touch.
10. Weight shifted to one side of body when standing.
11. Exhibits toe-touching while standing.

There are also a few other conditions with similar symptoms to a cruciate injury, which is why it is important to schedule an appointment to see your veterinarian if your dog is exhibiting any of the symptoms listed above.

Conditions with similar symptoms to cranial cruciate ligament tears/rupture:

1. Acute arthritis – related to lyme disease or immune disorders
2. Stifle (knee) joint sprain
3. Meniscus (cartilage within the knee) injury
   
4. Hip dysplasia
5. Patellar (knee cap) fracture or luxation
6. Myelopathies – diseases of the nervous system
