Abstract

A 5-year-old 6 kg male mongrel (case 1) and a 7-year-old 4.3 kg male yorkshire terrier (case 2) were presented to Chonbuk animal medical center (CAMC). Both animals had non-weight bearing hind limb lameness. Case 1 had complete rupture of cranial cruciate ligament with grade 3 medial patellar luxation. Case 2 had complete cranial cruciate ligament rupture with grade 4 medial patellar luxation. During surgery, in both cases, trochlear block recession was performed followed by CORA based leveling osteotomy (CBLO) and tibial tuberosity transposition (TTT). General soft tissue reconstructions for medial patellar luxation including medial releasing and lateral imbrication were also performed. Postoperatively, both animals demonstrated excellent recovery and regained normal weight bearing of the affected hind limb without any recognizable complication. CBLO followed by TTT can be a curative surgical option without complications in cases of cranial cruciate ligament rupture with high-grade medial patellar luxation in small breed dogs.
