Introduction: Understanding Luxating Patella in Dogs

Luxating patella, also known as a floating kneecap, is a common orthopedic condition that affects dogs. It occurs when the patella, or kneecap, moves out of its normal position in the groove of the thigh bone, causing the leg to lock or slip out of place. This can be a painful condition that affects a dog’s mobility, and it occurs most commonly in small dog breeds.

Symptoms of Luxating Patella in Dogs

Dogs with a luxating patella may display a range of symptoms, including limping, hesitation to run or jump, difficulty standing or climbing stairs, and a sudden yelp or cry of pain when the leg is moved in a certain way. Some dogs may also develop a bow-legged appearance or an abnormal gait. In severe cases, the affected leg may become permanently locked in place, causing the dog to drag the leg or hop on three legs.

Causes of Luxating Patella in Dogs

The exact cause of luxating patella in dogs is not fully understood, but it is thought to be a combination of genetic and environmental factors. Certain dog breeds, particularly small dogs such as Chihuahuas, Pomeranians, and Yorkshire Terriers, are more prone to developing this condition due to their conformation and size. Other factors that may contribute to the development of luxating patella in dogs include trauma, injury, or overuse of the leg, as well as obesity or poor nutrition.
