Plain-English summary
A 12-year-old male miniature Australian shepherd was brought in for limping on his left back leg, which had started suddenly over the past three months. The vet found that he had luxating kneecaps and a mass in his knee joint. After taking some samples and performing surgery, the mass was identified as a benign fatty tumor called a fibrolipoma. Following the surgery, the dog felt much better right away and returned to his normal activity levels within a few weeks.

Abstract
A 12 yr old male castrated miniature Australian shepherd dog presented for surgical consultation of historical bilateral medial patellar luxations with a 3 mo history of an acute onset of a left pelvic limb lameness. Physical examination confirmed medial patellar luxations and a mass effect of the left stifle medially. Radiographs showed medial distension of the joint capsule by a soft tissue opacity. Fine-needle aspirate of the left stifle revealed a mesenchymal cell population. Left medial parapatellar stifle arthrotomy found a fatty mass, which was excised at its base. A benign fibrolipoma was diagnosed on histopathology, and the excision was expected to be curative. The owners reported immediate improvement of perceived comfort postoperatively. At 2 and 24 wk, the dog returned to a normal level of function. Lipomas of the stifle, although rare, should be considered as a differential for intra-articular masses causing lameness.
