Patella luxation - PL

Patella luxation is a defect where the kneecap (patella) has a tendency to slip out of its position, it luxates. The cause of this might be that the trochlear groove in which the kneecap rests has to shallow and rounded sides and/or that the ligaments keeping the kneecap in place are too loose. PL can also be caused by an accident. The symptoms are that the cat suddenly stops when walking, with the leg stretched out to the rear. By backing a little the cat might get the kneecap to jump back into the right position. The cat might also be hurting in the knee and getting inflammations. Cats with symptoms can be operated.

PL seems to be polygenetic.
