Patellar Luxation in the Dog.

Canine patellar luxation is a complex condition with multifactorial developmental skeletal abnormalities that lead to quadriceps extensor mechanism malalignment and contribute to the luxation in a compounding manner. Surgical techniques to realign the quadriceps extensor mechanism and improve patellar stability include varying trochleoplasty techniques, tibial tuberosity transposition, soft tissue reconstruction, antirotational techniques, prosthetic implants, and corrective osteotomies. An individualized surgical plan must be created for each patient to address the clinically significant musculoskeletal abnormalities contributing to patellar luxation.
