Patellar luxation in dogs


Patellar luxation in dogs

With patellar luxation, your dog's kneecap slips out of its groove, which leads to limping, briefly lifting the leg or an unsteady gait. Depending on the grade, a veterinary assessment is necessary. Alongside this, joint nutrients such as glucosamine, chondroitin, green-lipped mussel, MSM, collagen, devil's claw and boswellia can meaningfully support the normal joint function.

What is a patellar luxation and how does it occur?

Patellar luxation, the lateral protrusion of the kneecap from its guide, is a stifle joint disorder that occurs mainly in small dogs. It can be congenital, i.e. inherited, or develop as a result of malalignment of the stifle joint.

Typically, in less severe cases (1 and 2), the kneecap usually springs back into the correct position independently and without pain, whereas in more severe cases (3 and 4), manual correction or even surgical intervention is necessary.

Risk factors and consequences

Although small dog breeds are particularly affected by this condition, larger dogs can also have a hereditary predisposition to it. In addition to genetic factors, diet, obesity and weak muscles also play a role in the development of patellar luxation. In the long term, the condition can lead to pain, restricted movement and even joint wear and tear, including arthritis, which can significantly impair the affected dog's quality of life.

The severity of patellar luxation is divided into different grades:

  • Grade 1: The kneecap only occasionally pops out of its groove and usually slides back into place spontaneously.
  • Grade 2: The luxation occurs more frequently; the kneecap sometimes remains outside the groove, but can still be brought back into place manually or through movement.
  • Grade 3: The kneecap is luxated most of the time, but can be brought back into place with pressure, but quickly pops out again.
  • Grade 4: The kneecap is permanently out of the groove and cannot be brought back into place.

Symptoms and Everyday Life with Patellar Luxation

The most common symptoms include sudden hopping on three legs, lameness, unsteadiness when walking, or a visible protective posture. In milder cases, owners often only notice occasional "pauses" in walking, while advanced stages can lead to pain and restricted movement. Diagnosis and assessment of the severity should always be performed by a veterinarian.

Diet and Management

In addition to veterinary treatment and, if necessary, physical therapy, an adjusted body weight can relieve pressure on the joints and positively influence the course of the disease. A high-quality, balanced diet, supplementation, and regular exercise (adapted to the dog's condition) are crucial. Micronutrients such as special joint nutrients can help support physiological joint function.

You and your dog: There are many wonderful ways to experience everyday life and enjoy special moments together with your dog. Whether on a walk, during training, or relaxing at home, being together enriches life in its own unique way.
