As your dog ages, a slipped kneecap can also lead to diseases of joints and bones, which can result in arthritis. Is Your Dog Suffering From Luxated Patella? If you think that your dog is suffering from a luxated patella or a slipped kneecap, the best thing to do is take him to the vet as soon as you can. Although a slipped kneecap may not seem like a serious condition to your young dog, it is a progressive disorder and can be debilitating if left untreated. Five Common Symptoms Of A Slipped Kneecap Symptoms usually start to appear when the dog is young, between the ages of six months to one year. But in some dogs, symptoms show up as early as around eight weeks of age, but remain undetected until the dog reaches maturity. Signs include:
* Difficulty climbing stairs.
* Occasional skipping or limping, especially during a run.
* Lameness on the leg, especially on the rear, that occurs frequently and ends suddenly.
* Difficulty squatting.
* Suddenly yapping in pain while walking or running, usually lasting for two to four strides. This dog is exhibiting textbook symptoms of luxated patella. Note the crouched gate and bow legs. In severe cases, the kneecap dislocates more often and lasts longer. Your dog will show discomfort and pain, seems bow-legged, and exhibit a crouching way of walking. Luxated patella is categorised in four grades, depending on the severity of the condition: Grade I: This is when the kneecap manually dislocates but goes back into place once the pressure is released. Considered as a mild case with treatment not necessary. However, you need to keep a close eye on your dog in case the condition gets worse. Grade II: The kneecap dislocates more often, either manually or automatically, when the joint is being flexed and continues to be dislocated until the joint is extended and the leg is turned into the opposite direction of the dislocation. Considered as the middle ground between mild and severe, dogs with grades I and II should be closely monitored in case the condition gets worse. Grade III: The kneecap dislocates on a regular basis, whenever the joint is flexed and extended. Dislocation is manually decreased when the joint is extended. This is considered to be severe enough to warrant surgery. Grade IV: The kneecap is permanently dislocated and cannot manually be put back into place. This is because the groove is too shallow or, in some cases, completely missing. Surgery is needed to fix this problem. Caring For Your Dog During And After Treatment Although luxated patella is not a condition that needs to be treated in the emergency room, getting your dog tested for this disorder prevents it from becoming worse. All dogs should be tested because a slipped kneecap can affect dogs of all breeds and sizes. However, if you own a small or a toy dog breed, you should have him tested for luxated patella as soon as possible. Responsible breeders should know that this condition is hereditary, and therefore, have their puppies tested at around six weeks of age, preferably before sending them to their new homes. Treatment Options For A Slipped Kneecap Physical tests, along with the length of time that the dog is showing symptoms such as limping, skipping, and carrying his leg, will determine his diagnosis. To indicate the severity of the condition, an X-ray of the thigh bone and the knee will be performed. Treatment is not required for Grade I, although you should check your dog in case the problem gets worse. For Grades II, III, and IV, surgery can be performed in order to repair the malformation. Surgery is done by an orthopaedic surgeon and includes correcting the dog's bone alignment, tightening his joint capsule, and potentially deepening the groove where the kneecap rides. Here we see a vet re-establish the groove of the knee joint (using a saw) to enable better patella mobility. (not for the squeamish) Although not a dire emergency, it is best to consult your vet as soon as possible if your dog is showing any symptoms. If surgery is needed, your vet will refer you to an orthopaedic specialist who will perform the operation. If your dog has a condition of Grade II, Grade III, or Grade IV, it is better to give him the surgery now before the condition worsens. Further damage of the bone and joint may make the outcome of the surgery less successful. Caring For Your Dog After The Surgery After surgery, your vet will prescribe medications for your dog's pain as well as anti-inflammatories to be taken for an average of one week. Your dog will need plenty of rest during this time, meaning very little activity for at least one or two weeks. He should be kept on the lead when outside the house. Keep him in a small and comfortable room to avoid him jumping, running around, or other types of activities that can put pressure on his knee. This dog is recovering well from surgery, although he's still struggling to put weight on his hind leg. Physical therapy will begin around one week after the surgery. Take him for a slow walk for about five minutes. If possible, take him swimming. Your dog should be able to handle longer walks on the lead six weeks after the surgery and should be able to have complete recovery and normal use of his knee approximately five-six weeks after the surgery.
