Fractured Patella Surgery in a Canine

When a dog fractures its patella, located where the hind leg bends, veterinarians usually perform surgery. The patella covers the joint like a knee cap.


A fractured patella cannot protect the stifle joint and prevent the joint from rotating counter-clockwise. Fractures occur most often in immature or young dogs.


Symptoms of a fracture include lameness, swelling at the knee and pain.

Surgical Reconstruction

Several surgical procedures exist. Veterinarians can surgically reconstruct the knee to improve knee and joint stability using sutures, wires, pins and screws.

Fixating the Patella

The primary goal of surgery is to “fixate” the patella and its adjoining joints, bones and ligaments to prevent improper rotation--often indicated by a “skipping gait” in the dog.

Restore Normal Function

Fractured patella surgery can reshape the bones and restore normal function of the knee. Surgery in smaller dogs might require a single pin to repair the fracture without reshaping the bones; however, in larger dogs, a more elaborate surgery, including a “buttress plate” may be required, according to Dog Health Guide.
