About The Webinar
Medial patellar luxation (MPL) is a common cause of lameness in small-breed dogs and is becoming increasingly more common in large-breed dogs. In a study that examined 1679 pet store puppies, 253 had at least one congenital defect (15%) amongst which 121 were patellar luxations (7.2%). In most reports between 15% and 25% of cases of medial patellar luxation present with concurrent Cranial Cruciate ligament (CCL) injury or rupture. Combined medial patellar luxation and cranial cruciate ligament disease is a challenging combination of conditions to manage.
The aetiopathogenesis of both conditions is still not fully understood however in most cases the MPL is considered to be present prior to and actively contribute to the development of the CCL rupture. MPL is most commonly a congenital disorder with multiple anatomical abnormalities of the pelvic limbs. Dogs with MPL may have an increased risk of developing CCL disease due to malalignment of the extensor mechanism and internal rotation of the proximal tibia, which in turn increases tension on the CCL predisposing it to deterioration.
Surgical treatment of MPL has traditionally focused on restoring more normal stifle joint biomechanics by realigning the quadriceps mechanism and stabilising the femoropatellar joint. Whilst surgery to treat CCL have focus on countering the cranial tibial trust by static or dynamic means. During this presentation we hope to review the surgical treatment options currently available to treat this complex set of conditions.
