Abstract

Osteoblastoma is a rare, benign, bone‑forming tumor that is frequently observed in the spine and long tubular bones. There are very few reports available on osteoblastoma of the patella. The present study reported an extremely rare case of a 22‑year‑old male adult who presented with an osteoblastoma of the patella. He was treated via intralesional curettage of the patella with subsequent bone grafting. After the intervention, he made an uneventful recovery with no recurrence after a follow‑up of 2 years. Making an accurate diagnosis of osteoblastoma of the patella is challenging and important for determining the correct treatment modality and prognosis, therefore, the present case may be helpful in the diagnosis and treatment of osteoblastoma of the patella.
