Isolated skeletal metastasis to the patella.

Metastases to the patella are rarely described in the literature. A 51-year-old man with stage IIIB adenocarcinoma presented to our clinic. One year after radiation and chemotherapy treatment, it was found that he had a metastasis in the right patella. Six months after incisional biopsy with curettage of the patellar lesion and placement of methylmethacrylate bone cement into the remaining patellar defect, he has no pain and is ambulatory. This case has been presented as a basis for palliative surgery in a patient with a rare metastatic tumor of the patella.
