Study Notes
Patella Luxation in Dogs
- Patella luxation can be medial or lateral and is classified as non-traumatic, traumatic, or iatrogenic
- Incidence of patella luxation is high in small breed dogs, with bilateral MPL being common
- Extensor malalignment in MPL is due to femoral deformities and shallow trochlear groove
- Traumatic patella luxation results in unilateral tear in retinaculum, while non-traumatic luxation causes retinaculum fibrosis
- Patella luxation is clinically graded from I to IV, with concurrent abnormalities including cranial cruciate ligament (CrCL) tear
- Diagnosis of patella luxation involves orthopedic examination and diagnostic imaging, with differential diagnoses including hip and stifle-related issues
- Orthopedic examination includes palpation for luxation, assessment of CrCL stability, and examination maneuvers
- Diagnostic imaging involves radiography to rule out osteoarthritic changes and other underlying pathologies
- Treatment strategies for patella luxation are grade and symptom-based, with surgical procedures including trochleoplasty and tibial tuberosity transposition
- Trochleoplasty techniques include recession trochleoplasty, abrasion trochleoplasty, and trochlear chondroplasty
- Tibial tuberosity transposition is commonly used for patella luxation treatment
- Patella groove replacement (PGR) is used for severe cartilage damage in trochlear grooves and does not address patella lesions
