Cruciate rupture also affects the knees, but in this case it affects the cruciate ligaments, a small pair of fibrous bands that hold the knee together. Cruciate rupture is more common in larger dogs, and usually happens suddenly when a dog is out playing. The most common situation is a dog out happily playing and running around who jumps and turns, then is suddenly very painful and can’t walk on one of their hind legs.
If you suspect your dog may be suffering from cruciate rupture it is advised to see your veterinarian as soon as possible as they can be more difficult to repair if left for a long period of time.
Cruciate ruptures nearly always need to be fixed surgically – if they are not repaired the knee bones will rub on each other, causing long term damage. We would always recommend a glucosamine supplement to help with the repair after the procedure and an Omega 3 supplement to help with inflammation. See suitable supplements here.
