Patellar Luxation(PL)
Also known as: Kniescheibenluxation · Luxatio patellae · Slipping kneecap · Patellaluxation des Hundes · Patellaluxation · …
Overview
What it is
Patellar luxation, also known as a luxating patella, is a physical condition affecting the knee joint where the kneecap slips out of its normal groove. This misalignment interferes with the mechanical movement of the hind leg and can cause the joint to lock. Over time, this abnormal friction can lead to painful joint wear and tear, known as osteoarthritis.
How it presents
Owners typically notice a sudden, temporary limp or a skipping gait where the dog runs on three legs for a few steps before returning to normal. These signs usually become apparent at a young age, typically between a few months and one year old.
Treatment
While mild cases can be managed with physical therapy, moderate to severe cases require surgical correction to stabilize the kneecap. Treatment costs typically range from 1,000 to 5,000 EUR per affected knee, depending on whether surgery is required.
