Osteolysis of the patella occurs in benign or malignant bone tumors, metastatic disease, osteolytic infections, degenerative, or metabolic bone disease. Several cases of patellar destruction secondary to gout have been reported. However, there has only been one case of bipartite patellar bone destruction secondary to gout reported in the literature. We encountered a patient with an osteolytic lesion of the bipartite patella suggesting a bone tumor or metabolic bone disease. A biopsy and histology examination suggested a diagnosis of gout tophi. This case demonstrated bilateral bipartite patella with gout involvement on the plain roentgenograms.
