Modified medial patellofemoral ligament reconstruction for severe bilateral congenital patellar luxation in a dog.

BACKGROUND

Lateral patellar luxation (LPL) is commonly diagnosed in large or giant breed dogs. In the surgical outcome for canine LPL, approximately half of the patients had complications, including reoperation and relaxation. Medial patellofemoral ligament (MPFL) reconstruction has been widely used for human repetitive patellar luxation. This case report describes that modified MPFL reconstruction with other surgical techniques might be effective for severe canine LPL repair.

CASE DESCRIPTION: An 11-month-old intact male Siberian Husky was referred to us with the main complication reported as bilateral hind lameness and LPL, diagnosed by a family doctor. Physiological examination showed bilateral patellar luxation (grade 4). We performed general surgical techniques with modified MPFL. The patient showed good prognosis.

CONCLUSION

This report suggests that modified MPFL with general surgical techniques for LPL might be an effective surgical technique in dogs.
