Patellar luxation in the dog and cat
  1. John Ferguson

    John Ferguson graduated from the Royal (Dick) School of Veterinary Studies, Edinburgh, in 1989. He spent four years in mixed general practice in York and Herefordshire, during which time he developed an interest in small animal surgery. He subsequently returned to Edinburgh in 1993 where he completed a three-year residency in small animal orthopaedics and gained his certificate in the same subject. He is currently in practice near St Andrews in Fife where he runs an orthopaedic referral service.


PATELLAR luxation is a commonly seen orthopaedic problem in veterinary practice. Diagnosis of the condition is usually straightforward. However, a knowledge of the normal anatomy, function and interrelationship between the hip and stifle joints, femur, tibia and soft tissues is necessary if the surgeon is to choose the most appropriate method of treatment. This article describes medial and lateral patellar luxation, the clinical signs, diagnosis and treatment options available in the dog and cat.
