Patellar luxation – dog Dara

Patellar luxation (dislocation of the kneecap) in dogs is a condition in which the kneecap shifts or moves out of its normal position on the femur. It frequently affects small breeds—such as Yorkshire Terriers, Pomeranians, Chihuahuas and others —causing a characteristic “skipping” gait, intermittent hind-limb lameness, or a sudden, unnatural hop while moving.

Dara is an 8-year-old Chihuahua who was diagnosed with patellar luxation at a young age. The condition is classified according to severity, ranging from Grade 1 to Grade 5.

Dara had previously underwent surgery on her left leg when she was young. Now, seven years later, she has been experiencing a pronounced limp in her right hind leg for some time, along with an inward rotation of the limb that prevents her from walking normally. Patellar luxation is a complex condition, and treatment depends on many factors.

In Dara’s case—where patellar luxation was accompanied by significant pain and a disruption of the extensor mechanism—we opted for a combination of soft-tissue techniques and corrective osteotomies to address the dislocation and alleviate the pain. The goal of the surgery was to restore the proper function of the knee’s extensor mechanism and prevent the patella from slipping out of the trochlea.

One month post-surgery, Dara is walking and playing normally; her leg now points straight and pain and discomfort have been minimized.
