Plain-English summary
A 9-year-old female Rottweiler was diagnosed with a bone tumor called osteosarcoma in her right leg, seven years after she had surgery to replace her hip joint. The tumor caused a fracture in her femur and problems with the hip implant. While it's unclear if the surgery contributed to the tumor, this case highlights a rare complication that can occur after hip replacement in dogs. Treatment options would typically include surgery and possibly chemotherapy, but the specific outcome for this dog wasn't detailed.

Abstract
Osteosarcoma involving the distal right femur was diagnosed in a nine-year-old female neutered Rottweiler seven years after total hip arthroplasty had been performed on that limb. The findings were consistent with a primary bone tumour and pathological fracture of the right femoral condyle with loosening of the orthopaedic implant and fracture of the polymethylmethacrylate at the distal aspect of the femoral component. Possible hypotheses to explain the association of osteosarcoma with total hip arthroplasty suggest that the neoplastic process was the result of some derangement of host tissue and the healing process or that the implants or their by-products were carcinogenic. Given the large number of total hip arthroplasties that are routinely performed in dogs, the development of a malignant lesion appears to be an extraordinary complication and may be completely coincidental.
