In this article by YourCatCareguide we will explain everything about patellar dislocation in dogs , their symptoms, treatment and diagnosis.
Types of dislocation and symptoms
The patella is a small bone that exists in the anterior part of the knee. When this bone moves from its site due to genetic or traumatic causes, the dog suffers from pain and problems in moving, which in severe cases can render the affected extremity unusable. In cases of traumatic patellar dislocation it is usually associated with rupture of the anterior cruciate ligament of the knee.
Existem dois tipos de luxação de patela, a luxação patelar medial e a luxação patelar lateral. A luxação medial é a mais frequente, ocorrendo em 80% dos casos. A lateral converte-se em bilateral com frequência. As fêmeas, os cães pequenos e os toy são os mais propensos a sofrer dela. Uma vez detetada a luxação, esta pode se classificar em 4 graus.
Graus de luxação da patela:
- Grau I – As caraterísticas da luxação do primeiro grau são as seguintes: interrupção na luxação, deixando o cão a mancar quando a rótula sai do seu lugar. Os cães que sofrem disso a cada três ou quatro passos flexionam a para ou dão um pequeno pulo.
- Grade II – Dislocation of second degree is characterized by being a dislocation much more frequent than the previous one. The ball joint moves frequently. Many dogs suffer for years from this disease, before drifting into a progressive arthritis. The symptoms are a slight external rotation of the paw when walking, in which the dog limps and can cause a great incapacitation in the dog.
- Grade III – Third degree dislocation is characterized by: the kneecap is displaced permanently without periods of improvement. It causes considerable external rotation of the affected paw. The dog limbs moderately.
- Grade IV – Fourth degree dislocation is characterized by the following symptoms: the patella remains displaced chronically. The dog by manacing causes a considerable rotation of the paw very painful and prevents the dog from making certain efforts, such as climbing stairs, getting in the car or climbing onto the sofa. When the dislocation is bilateral, the dog rests on its hind legs when walking. In more severe cases it can be confused with hip problems.

At the same time, and as a consequence of the diagnosis of patellar dislocation in dogs, it should be taken into account whether there are damages that have caused this congenital or traumatic problem, for example in the ligaments.
Treatment of patellar dislocation
