A luxating patella is a condition when the patella, or kneecap, dislocates or moves out of its usual position. This condition. in humans, is also known as a trick knee.
Especially in little and miniature breeds of dogs, patellar luxation is a prevalent issue. In most cases, the problem doesn’t appear until between 4 and 6 months. It can also affect cats, particularly domestic short-haired cats. It also happens in people, and anterior cruciate ligament injury may contribute to those cases.
There have been numerous cases of patella luxation in animals of different species, including goats, cattle, alpacas, and miniature pigs.
