Course Description

Patellar luxation is one of the most common causes of lameness in dogs, affecting large and small breeds. Luxation may be medial, lateral or bidirectional and often presents concurrent with a variety of underlying conditions, often in combinations, including: patella baja/alta, femoral varus/valgus/torsion and tibial varus/valgus/rotation/torsion.

To address patellar luxation comprehensively, a firm grasp of the principles of hind limb alignment, Center of Rotation of Angulation (CORA) and rules for corrective osteotomies are essential.

Conventional surgical techniques include: Tibial Tuberosity Transposition (TTT), Distal Femoral Osteotomy (DFO), Proximal Tibial Osteotomy (PTO) and Block/Wedge Sulcoplasty.

To address severe cases where conventional techniques are insufficient for capture of the patella, the KYON Patellar Groove Replacement (PGR) prosthesis is advised. (Learn More About PGR)

This 2 day course will concentrate on the pathophysiology, diagnosis, and surgical correction of patellar luxation by both conventional and state-of-the-art methods.

Lectures include the Putnam Singleton Grading System, radiographic interpretation, the principles of CORA, Paley’s rules of osteotomies, surgical approaches, sulcoplasty, tibial tuberosity transposition, and patellar groove replacement.

Day 1 labs will focus on radiographic evaluation and surgical planning.

Day 2 labs include two wet labs with pre and post radiography and review. All participants will perform, at minimum, tibial tuberosity transposition, sulcoplasty and PGR. 

We are honored to have Dr. Massimo Petazzoni and Prof. Otto Lanz as the instructors for this program.
