Healthy Patellae in Dogs219

The patella, also known as the kneecap, is a small bone that sits in front of the knee joint. It helps to stabilize the joint and allows for smooth movement. In dogs, the patella can sometimes become dislocated, which can cause pain and lameness. Patellar dislocation is a common problem in small breeds, such as Chihuahuas, Yorkshire Terriers, and Pomeranians.

There are two main types of patellar dislocation: medial and lateral. Medial patellar dislocation is the most common type, and it occurs when the patella slips out of place to the inside of the knee. Lateral patellar dislocation is less common, and it occurs when the patella slips out of place to the outside of the knee.

Patellar dislocation can be caused by a variety of factors, including:
Trauma: A direct blow to the knee can cause the patella to dislocate.
Congenital defects: Some dogs are born with a shallow groove in the femur where the patella sits. This can make the patella more likely to dislocate.
Obesity: Overweight dogs are more likely to have patellar dislocation because the extra weight puts stress on the knee joint.
Muscle weakness: Weak muscles around the knee can also contribute to patellar dislocation.

The symptoms of patellar dislocation can vary depending on the severity of the dislocation. Some dogs may only experience mild lameness, while others may be unable to bear weight on the affected leg. In severe cases, the patella may become trapped outside of the knee joint, which can cause intense pain.

If you think your dog may have a patellar dislocation, it is important to take them to the veterinarian as soon as possible. The veterinarian will be able to diagnose the dislocation and recommend the best course of treatment. Treatment for patellar dislocation typically involves rest, pain medication, and physical therapy. In some cases, surgery may be necessary to correct the underlying cause of the dislocation.

Preventing patellar dislocation is not always possible, but there are some things you can do to reduce your dog's risk:
Maintain a healthy weight: Overweight dogs are more likely to have patellar dislocation, so it is important to keep your dog at a healthy weight.
Strengthen your dog's muscles: Strong muscles around the knee can help to stabilize the joint and prevent dislocation. You can help to strengthen your dog's muscles by taking them for regular walks and playing games that involve running and jumping.
Avoid activities that put stress on the knee joint: Activities such as jumping from high heights or running on slippery surfaces can put stress on the knee joint and increase the risk of patellar dislocation. If your dog has a history of patellar dislocation, it is important to avoid these activities.

By following these tips, you can help to reduce your dog's risk of patellar dislocation and keep them healthy and active.
