Luxating patella, also known as a floating kneecap, is a condition that affects the stability and alignment of the knee joint in dogs. To understand this condition better, let’s explore what exactly a luxating patella is, its causes, and the symptoms to look out for.

What is a Luxating Patella?

A luxating patella occurs when the patella, which is normally located in a groove at the end of the femur bone, moves out of its normal position. It can move towards the inside (medial luxation) or the outside (lateral luxation) of the leg. As a result, the knee joint becomes unstable, leading to discomfort and mobility issues in affected dogs.

Causes of Luxating Patella in Dogs

There are various factors that contribute to the development of luxating patella in dogs. These include:

1. Genetics: Certain dog breeds are more prone to luxating patella due to hereditary factors. Breeds such as Chihuahuas, Pomeranians, Yorkshire Terriers, and Poodles are commonly affected.

2. Muscular Imbalances: Weak or imbalanced muscles around the knee joint can increase the risk of luxating patella. This can be caused by improper development or injury.

3. Trauma: In some cases, a traumatic injury to the knee can lead to the displacement of the patella.

4. Abnormal Bone Structure: Dogs with abnormal bone structure, such as a shallow patellar groove or a misaligned femur bone, are more prone to developing luxating patella.

Symptoms to Look Out For

Identifying the symptoms of luxating patella in dogs is crucial for early detection and intervention. The following signs may indicate a potential issue:

1. Intermittent Lameness: Dogs with luxating patella may experience occasional limping or favoring of one leg. The lameness may come and go, depending on the severity of the condition.
