Plain-English summary
A 9-year-old spayed female Cane Corso was brought in because she was suddenly unable to put weight on her right back leg for a week. The dog had previously undergone a surgery called tibial tuberosity advancement (TTA) six years earlier. X-rays showed a serious bone lesion and a fracture in the tibia, which were found to be consistent with osteosarcoma, a type of bone cancer. Unfortunately, the owner chose to have the dog euthanized due to the severity of the condition.

Abstract
A 9-year-old spayed female Cane Corso dog was presented with a 1-week history of an acute right hind limb non-weight-bearing lameness. Six years previously, a right tibial tuberosity advancement (TTA) procedure had been performed. Orthogonal radiographs of the right pelvic limb taken before presentation revealed a comminuted displaced mid-diaphyseal tibial fracture. An aggressive bone lesion with osteolysis and periosteal reaction of the proximal tibia were evident that were most consistent with a primary bone tumor. The owner elected to have the dog euthanized. After euthanasia a fine-needle aspirate of the right proximal tibia was submitted for clinical pathology. Cytology and alkaline phosphatase staining of the fine-needle aspirate were consistent with osteosarcoma. Key clinical message: To the authors' knowledge, this is only the second reported case of osteosarcoma at the site of a TTA. Implantassociated osteosarcoma has been associated with tibial plateau levelling osteotomy (TPLO) and fracture repair.
