Luxating Patella in Dogs

Luxating Patella - What is It?

A luxating patella is a dislocating kneecap. The patella is also called the kneecap and is bound in place by ligaments, however these ligaments might get lax as the consequence of an injury or congenital abnormality. It's more common in littler dog breeds, and is frequently a continual issue.

Since a luxating patella can be inherited, afflicted dogs should not be bred. Likewise, you should not acquire a dog with a family history of luxating patellas.

Luxating Patella - What Causes It?

Patella Luxation can be a consequence from an injury or congenital malformations. A congenital abnormality where the dogs legs turn inwards could also be a causal agent. If the trochlear groove, this is the groove the patella glides in is too shallow or if the distal attachment of the patellar ligament is medial instead of central, the kneecap will luxate medially while the knee joint is bent. Once this happens, the dog will have trouble carrying weight on the leg until the ligament comes back into proper alignment. Occasionally just one knee joint is affected, however the impairment can turn bilateral, affecting both of the dogs legs in approximately fifty percent of cases.

Patellar Luxation Treated?

The treatment protocol and long term prognosis largely depends on the severity of the disorder, which is measured by how often the patella luxates, and how well it shifts back into the proper anatomical position, and whether there are secondary issues like degenerative joint disease. Moderate to severe cases frequently call for surgical operation to make certain that the patella stays in the patellar groove in the femur, and to prevent osteoarthritis from developing in the future. Physical exercise limitation is crucial for a period of time after operation, and the outcomes are generally extremely good.

Patellar luxation can be categorized into 4 grades, with grade 1 constituting the mildest. Grade 1 patellar luxation might be chanced upon as an incidental finding. Severe circumstances of luxating patella in growing dogs could lead to leg disfigurement. Surgical procedure is typically suggested in moderate or severe cases of luxating patella to steady the kneecap and fix the underlying anatomical malformation. Surgical correction might stop the advancement of osteoarthritis, but this is not guaranteed, and reluxation is a conceivable complication of the surgical procedure.

Can A Luxated Patella Be Fixed?

If your dog is merely experiencing a moderate luxating kneecap, then the patella can sometimes actually correct itself or your veterinarian can manually put the kneecap back in place. If the vet decides this is to be done then your dog will most likely be given pain drugs. Cases that are more severe will require surgical operation to fix the ligaments.

If the operation is executed prior to arthritis occurs, the forecast is very good, and your dog ought to regain complete use of its leg. But, if arthritis has set in prior to the operation, the knee joint will continue to be slightly painful, particularly in frigid weather, and the use of the leg can be affected.
