An Alaskan Malamute underwent unilateral tibial tuberosity advancement (TTA) surgery to stabilise a stifle joint with a deficient cranial cruciate ligament. The dog made an excellent recovery with no postoperative complications, until 20 months post-surgery when he presented with acute onset ipsilateral pelvic limb lameness. Osteosarcoma (OSA) was diagnosed adjacent to the titanium implants. Currently, there is a paucity of information on the epidemiology of OSA adjacent to orthopaedic implants in canine patients. The clinical, radiological and pathological findings of this case of periprosthetic OSA, and a potential causal relationship between titanium implants and bone neoplasia, are discussed.

Marked variation exists in the tension applied during fabello-tibial suture application, both within and between surgeons. This variation may lead to inconsistent clinical outcomes. Further studies are required to determine the clinical consequences of this marked variation in extracapsular suture tensioning.
