Abstract: Patella luxation is a developmental condition in dogs that results in intermittent or persistent luxation of the patella from the trochlear groove of the femur. Medial patella luxation (MPL) is more common than lateral luxation. Chondrodystrophoid breeds are the most commonly affected type of dog however patella luxation can occur in any breed of dog. Large breed dogs with MPL are usually more difficult to resolve than small breeds. Bilateral MPL has been estimated to occur in approximately 20 – 50% of cases. Secondary cruciate disease occurs in approximately 20% of cases of MPL. Clinically significant MPL requires surgical correction. Complications following surgical correction of MPL are common and include reluxation and implant failure. Reluxation is the most commonly reported complication with recurrence rates as high as 48% reported. The main reasons for recurrence of MPL after surgical correction are surgical decision-making errors and/or technical errors. The decision-making errors primarily result from a failure on the part of the surgeon to identify the musculoskeletal abnormalities present in an individual case and / or failure to perform the procedures necessary to resolve those abnormalities. This session will focus primarily on surgical decision-making and surgical options to correct MPL...
