Signs Your Dog May Have a Cruciate Ligament Injury

What is a cruciate ligament injury in dogs?

The cranial cruciate ligament is an important structure within the knee joint. It helps keep the joint stable during movement. When this ligament becomes damaged or ruptures, the knee can become unstable, painful and less able to support normal movement.

Ivy Lodge Vets highlights cruciate ligament injuries as a common orthopaedic condition in dogs and notes that surgery is often required to repair the ligament and restore mobility.

What are the common signs of a cruciate ligament injury?

The most common sign is limping on a back leg, but symptoms can vary depending on how severe the injury is. Some dogs suddenly become lame after exercise, while others show more gradual signs such as stiffness or a reduced willingness to stay active.

Common signs to look out for

• Limping on a back leg
• Stiffness after rest
• Difficulty getting up
• Reluctance to run, jump or use stairs
• Reduced activity levels
• Pain or discomfort around the knee
• Changes in the way your dog walks or stands

Do cruciate injuries always happen suddenly?

Not always. Some dogs seem to become lame very suddenly, especially after exercise or twisting awkwardly, but in other cases the ligament can weaken over time. This means symptoms may start off mildly and gradually become more noticeable.

Because the signs can build slowly, some owners do not realise how much discomfort their dog is in until the problem becomes more advanced.

Which dogs are more likely to develop cruciate problems?

Cruciate ligament injuries can affect many different dogs, but they are often discussed more commonly in active dogs and medium to large breeds. Ivy Lodge’s surgery page explains that TPLO is often recommended for active dogs and medium to large breeds where a strong, long-term repair is needed.

That said, any dog showing signs of hind leg lameness or knee pain should be assessed properly rather than assuming it is just a minor strain.

How are cruciate ligament injuries diagnosed?

Diagnosis starts with a veterinary examination. Your vet will usually assess how your dog walks, examine the affected leg, and check the knee joint for pain, swelling or instability. Depending on the case, further investigation may also be recommended.

Ivy Lodge’s orthopaedics service says the orthopaedic journey can include consultation, physical examination and diagnostic imaging such as X-rays or ultrasound as part of building a personalised treatment plan.

What treatment might be needed?

Treatment depends on the dog, the severity of the injury and the level of joint instability. Some dogs may initially need pain relief, rest and a clear management plan, while others may need orthopaedic surgery to restore stability more effectively.

Ivy Lodge notes that TPLO is a commonly performed orthopaedic procedure used to treat cranial cruciate ligament injuries in dogs and help restore stability to the joint.

Treatment may involve

• Orthopaedic assessment
• Pain management
• Rest and controlled exercise
• Follow-up appointments
• Physiotherapy and rehabilitation
• TPLO surgery where appropriate

Can dogs recover well after treatment?

Many dogs can do very well with the right diagnosis, treatment and recovery support. Ivy Lodge’s orthopaedics page highlights post-operative care that may include pain management, physiotherapy, rehabilitation, follow-up appointments and home care instructions.

Recovery plans will vary from dog to dog, so it is important to follow veterinary advice closely and avoid returning to full activity too soon.

When should you speak to a vet?

If your dog is limping on a back leg, seems stiff after exercise or rest, or is showing ongoing signs of discomfort around the knee, it is worth arranging an assessment. Persistent lameness should not be ignored, especially if it is affecting normal daily movement.

Early diagnosis can help you understand what is causing the problem and what the most suitable treatment options may be.
