Rupture of the CCL is the most common cause of hind limb lameness in dogs. Large and giant breeds are particularly affected although any breed and size of dog can rupture their CCL. Some dogs can be affected before they are two years of age. The cranial cruciate ligament (CCL) is an important ligament inside the knee (stifle) joints of dogs. In people it is referred to as the anterior cruciate ligament (ACL). The ligament plays an important role in stabilising the stifle during weight-bearing. It prevents the shin bone (tibia) moving forwards relative to the thigh bone (femur). Unlike in humans where a rupture is often associated with an injury, in dogs the cruciate ligament tends to undergo degenerative changes that weaken it prior to rupturing. This important difference explains why treatment options in dogs are quite different to those in people. Rupture of the CCL is associated with the development of osteoarthritis within the stifle. Osteoarthritis tends to be a progressive disorder and it is dubious whether treatment of the CCL rupture reduces or stops this progression. The signs of CCL rupture can be quite variable as rupture may be sudden and complete, or gradual and partial. The key signs are hind limb lameness and stiffness. The latter is generally most evident after rest following exercise. Difficulty rising and jumping are common features in dogs with both knees affected. Occasionally ‘clicking’ noises may be heard. Some dogs with CCL rupture can be managed satisfactorily without the need for surgery. The smaller the dog, the more likely it is that this approach will be successful. However regardless of the treatment method used hydrotherapy can help by counteracting muscle wastage and strengthening muscles, allowing the dog to continue exercising in a zero impact environment, assisting with weight management, pain reduction and improving blood circulation. So phone Chesterfield Hydrotherapy Referral Centre today to see how we can help you manage your dogs CCL.
