The cranial drawer test is a physical examination technique used by veterinarians to diagnose a torn cranial cruciate ligament (CCL or ACL) in a dog's knee (stifle joint). It measures joint instability by attempting to slide the tibia (shin bone) forward relative to the femur (thigh bone) while the dog is in a relaxed or sedated state.

What is a positive drawer test for a dog?

This test isolates the CCL and eliminates joint compression. Your veterinarian holds the upper bone (femur) static and pulls the lower bone (tibia) forward and way from the femur. This motion is just like pulling a drawer open. If the tibia can be pulled forward (cranial drawer), then the test is positive.

What does a positive drawer test indicate?

If the tibia pulls forward or backward more than normal, the test is considered positive. Excessive displacement of the tibia anteriorly suggests that the anterior cruciate ligament is injured, whereas excessive posterior displacement of the tibia may indicate injury of the posterior cruciate ligament.

How to tell if a dog has a torn meniscus?

While you can detect meniscal tears using advanced imaging (MRI and CT) , the most common way to diagnose meniscal tears in dogs is via an arthrotomy (small opening in the joint capsule) or arthroscopically (using a keyhole camera). If the meniscus is normal, no further treatment is required.

What are three signs of a meniscus tear in the knee?

Three key signs of a meniscus tear are pain and swelling, a catching or locking sensation in the knee, and instability or weakness, often described as the knee "giving way," alongside a potential popping sound at the time of injury, making it hard to fully bend or straighten the leg.

Can a dog's torn meniscus heal on its own?

If your dog has slightly torn or injured the menisci, they may self-heal with a little help from you. Keep ice on the minor injury and keep your dog from high activity. You may want to slow them from normal activity as well.

What test confirms an ACL tear?

The Lachman test is a specific clinical exam technique used to evaluate patients with a suspected anterior cruciate ligament (ACL) injury. The test relies on proper positioning and technique and is regarded as the most sensitive and specific test for diagnosing acute ACL injuries.

What happens if an ACL tear goes untreated?

If an ACL tear is left untreated, it can cause future injuries such as: Meniscal injury. Knee instability. Damage to surrounding cartilage.

Would my dog be able to walk if he tore his ACL?

If your dog's cruciate becomes injured or torn, your dog's knee will become unstable, reducing your pup's ability to run and walk normally and causing pain.

How do dogs act when they have a torn ACL?

In addition to decreased mobility, you may notice that your dog is no longer able to sit “squarely,” meaning that they'll stick their injured leg out to the side when seated to avoid pressure on that limb. An indicator of a torn ACL is the presence of the “drawer sign”.

What can be mistaken for an ACL tear in dogs?

The dog equivalent of a human ACL (anterior cruciate ligament) tear is a Cranial Cruciate Ligament (CCL) tear, also known as Cranial Cruciate Ligament Disease (CCLD) or Rupture (CCLR), which is a very common injury in dogs, causing hind leg lameness, pain, and long-term arthritis, often resulting from degeneration rather than acute trauma like in humans.

How can you tell if a dog has a torn ligament?

A dog ligament tear (CCL injury) often shows as sudden limping, reluctance to put weight on a hind leg, difficulty rising or jumping, swelling around the knee, stiffness, an abnormal "toe-touching" posture, or an awkward sit with the leg out to the side. You might also hear a pop at injury, notice muscle loss (atrophy) in the leg, or see decreased activity levels.
 

How to know if a dog's ACL is torn?

Symptoms of a torn ACL (or CCL, cranial cruciate ligament) in dogs include sudden or gradual limping, refusing to bear weight on a hind leg, holding the leg up, "toe-touching," stiffness, swelling around the knee, difficulty jumping or rising, and sitting with the leg extended sideways. An audible "pop" or "click" during activity can also signal a tear, with severe cases involving constant lameness.
 

What happens if you don't fix an ACL tear in a dog?

Your dog will begin favoring the non-injured leg. While the injured knee is becoming less and less used because of the partial tearing, additional pressure is put on the other knee. This is one reason why in 60% of cases, a cruciate ligament tear in one knee will later lead to an injury of the other knee.

Will walking on a torn ACL make it worse?

Over time, the pain will often subside, and the knee can feel fine with straight walking, but twisting or turning will often remain difficult. Walking with a torn ACL can worsen the injury and increase the risk of needing surgery or other more intense treatment.

Can a dog live a normal life with a torn ACL?

A healthy dog is a happy dog. Unfortunately, sometimes our pups can suffer an injury that could lead to a torn ACL. While dogs can live with a torn ACL, their quality of life is affected. Getting your pup to the vet immediately is important, as a torn ACL without treatment can require surgery.

What are three signs of an ACL tear?

Common ACL tear symptoms include:

• Feeling or hearing a pop in the knee.
• Severe pain, instability, and swelling in your knee.
• Being unable to bend and move your knee either fully or partially.
• Inability to stand up and hold your weight.

Will a brace help a dog with a torn ACL?

A torn anterior cruciate ligament can severely impact your dog's mobility and quality of life. Fortunately, a dog stifle or knee brace can be an effective solution to support your pet during the healing process.

What supplements are good for dogs with torn ACL?

Common ingredients for a high quality joint supplement for a torn ACL include glucosamine, chondroitin, MSM, & Omega 3 fatty acids. Alpha Dog Nutrition's Joint Lubrication Bundle has all of these critical ingredients to help avoid knee & leg lameness after ACL surgery or TPLO surgery.
