  • Title: Determining the Variation in the Tibial Tuberosity Transposition Distance That Is Required to Correct the Quadriceps Angle With the Severity of Medial Patellar Luxation of the Canine Stifle Joint.
    Author: Fujita Y, Kaneko H.
    Journal: Top Companion Anim Med; 2022; 47():100637. PubMed ID: 35051650.
    Abstract:
    The aim of this study was to evaluate the transposition distance in in vitro canine medial patellar luxation (MPL) models of different severity grades using a single radiograph of the stifle joint. Each MPL grade model was generated with manipulation and evaluated by palpating the stability of the patella. An anterior-posterior radiograph of the entire hind limb with extended hip and stifle joints, including the iliopubic eminence, was used for all measurements. The quadriceps angles and the percentage of the transposition distance to the maximum width of the proximal tibia were measured. Our results demonstrated that when the tibial tuberosity transposition procedure is performed in a clinical setting, the required distance to correct the abnormal direction of the extensor mechanism in the canine stifle joint was greater in severe grade MPL than in mild grade MPL.
