Editing Luxating patella (section)

==In animal breeds==
Most cases of patellar luxation are medial, and this is frequently a congenital problem in toy- and miniature-breed dogs.<ref>{{cite journal |last1=Engdahl |first1=Karolina |last2=Bergström |first2=Annika |last3=Höglund |first3=Odd |last4=Hanson |first4=Jeanette |title=The epidemiology of patellar luxation in an insured Swedish dog population |journal=Preventive Veterinary Medicine |date=September 2023 |pages=106034 |doi=10.1016/j.prevetmed.2023.106034 |url=https://www.sciencedirect.com/science/article/pii/S0167587723001988|doi-access=free }}</ref> Breeds showing a predisposition for medial patellar luxation include miniature and [[poodle|toy Poodles]], [[Maltese (dog)|Maltese]], [[Jack Russell Terrier]]s, [[Yorkshire Terrier]]s, [[Pomeranian (dog)|Pomeranian]]s, [[Pekingese]], Patterdale Terriers, [[Chihuahua (dog)|Chihuahua]]s, [[Cavalier King Charles Spaniel]]s, [[Papillon (dog)|Papillon]]s, [[Boston Terrier]]s, [[Plummer Terrier]]s and [[Teddy Roosevelt Terrier]]s. Large-breed dogs are also affected, and the Labrador retriever seems particularly predisposed.

Patellar luxation is less common in cats than in dogs. Predisposed breeds include the [[Devon Rex]] and the [[Abyssinian (cat)|Abyssinian]]. Although the specific cause of patellar luxation is unknown in these cases,  a defect in hind limb conformation is generally agreed to be the underlying cause.<ref>[http://www.vetspecialists.co.uk/06_Animal_Welfare/Orthopaedics/Patellar_Luxation.html Patellar Luxation, canine and feline (cat and dog) veterinary factsheets<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20080427204435/http://www.vetspecialists.co.uk/06_Animal_Welfare/Orthopaedics/Patellar_Luxation.html |date=2008-04-27 }}</ref>
