When your dog has problems with a back leg limp it may be due to cruciate disease. FAQs on cruciate disease management at Pittwater Animal Hospital.

What does it mean when your dog has injured their cruciate or ACL?

The cruciate ligament is a very important structure in the knee. The cruciate ligament is deep in the middle of the knee joint and keeps the knee stable. If the cruciate ligament is strained it can cause pain and swelling of the knee. If the cruciate ligament is torn,the knee joint becomes unstable causing significant lameness and often pain. 

How do we diagnose a cruciate injury?

A cruciate injury will cause either sudden onset lameness of a back leg or chronic pain of a back leg centred on the knee. Your veterinarian will palpate the entire back leg. When examining the knee (or stifle) there may be pain or swelling in the joint. The cruciate ligament is stressed by extension of the knee and a cruciate stability test will be part of the veterinary examination.

To get a clear diagnosis your dog is anaesthetised and the joint is palpated looking for changes in stability. Xrays of the knee are taken under a general anaesthetic. These xrays may show a joint effusion as well as a change in position of the tibial fat pad.

How do we treat a cruciate ligament strain?

If there is pain in the knee but no instability, your veterinarian may diagnose a cruciate strain. Strains may be treated with rest and anti-inflammatories. However, many dogs with cruciate strains will start to develop ongoing arthritic changes. To avoid the development of osteoarthritis it is often better to opt for a surgical approach to a dog with on going cruciate strain even if there is no instability.

How do we treat a cruciate tear?

A knee with a torn cruciate ligament will usually be unstable. The ligament that stabilises the knee is damaged and will never regenerate. This torn ligament will also cause an ongoing arthritic process in the knee. Surgery on the knee is by far the best option for any dog that has a torn cruciate ligament. If your dog has a torn cruciate ligament it is best to consult one of our very experienced veterinarians. At Pittwater Animal Hospital Dr Heidi Furber and Dr Jill King have a special interest in the treatment and management of cruciate disease. They can advise you about further diagnostics, management and treatment for the cruciate injury.

Why are some knee injuries more painful then others?

Having a torn cruciate with an unstable knee joint is not necessarily painful, but it does cause ongoing abnormal wear to the knee. Some dogs with cruciate injures are extremely painful and debilitated. This usually indicates damage to the menisci in the knee joint. A torn meniscus can feel like having a sharp stone in the knee joint. Dogs with this problem can be very miserable. During surgery, the joint is thoroughly examined and meniscal tears addressed.

What happens if you can’t afford cruciate surgery?

Without surgery, a dog with an unstable cruciate will always have a problem knee. Sometimes due to financial constraints or other health problems, surgery is not an option. In these cases Dr Heidi Furber or Dr Jill King can start your pet on an intensive protective plan to manage the injured knee. It will be very important to protect the other knee as often a dog that injures one cruciate ligament will damage the other knee.

What do you do if you are worried about cruciate disease in your dog?
