Abstract
An 8 kg, 9-month-old castrated male Shiba Inu presented with a history of intermittent bilateral hind limb lameness. On examination, grade III medial patellar luxation of the bilateral hind limbs was diagnosed. A novel surgical method involving relatively noninvasive tibial tuberosity transposition was used to restore normal alignment of the quadriceps mechanism. The procedure involved an incision on the medial cortical bone of the tibial tuberosity along the tibial crest and placement of a cortical screw on the medial side of the tibial crest to laterally transpose the tibial tuberosity. Lameness and patellar luxation of bilateral hind limbs were improved at a 3-month postoperative examination. This technique could be considered an effective treatment for medial patellar luxation in skeletal immature patients.
