“…The aggressive variants of osteoblastoma usually present with more intense pain, which can be due to localized areas of destruction (14). The most common symptoms of osteoblastoma of the patella are pain and swelling (7,8). Local tenderness may be noted during physical examination (8).…”

“…The imaging manifestations of osteoblastoma differ depending on its location, and the results lack specificity. The most frequent X-ray manifestations of the osteoblastoma of the patella are that of an osteolytic lesion, with or without matrix mineralization and pathological fracture of the patella, surrounded by a high-density sclerotic margin with no evidence of extra-articular invasion (7,15). Aggressive spinal osteoblastoma can break through the bony cortex and invade the spinal canal and paravertebral soft tissue (16,17).…”

“…The pathological examination findings of osteoblastoma reveal that the lesion is composed of irregular trabeculae of woven bone, lined by active osteoblasts within a copious vascularized fibrous stroma containing focal multinucleated giant cells (7,8). The cartilaginous matrix may be present rarely (19).…”

“…In theory, the treatment options available for osteoblastoma of the patella include intralesional curettage followed by bone grafting or bone cement, en-bloc resection of the lesion, and even patellectomy. To treat the osteoblastoma of the patella, intralesional curettage with subsequent allogeneic bone grafting has been previously performed (7,8). Intralesional curettage can be effective but is related to a recurrence rate of 15-25% (23).…”

“…Osteoblastoma of the patella is extremely rare, accounting for approximately 2% of all tumors of the patella (4,5). To the best of our knowledge, very few cases of osteoblastoma of the patella have been reported (Table I) (6)(7)(8)(9)(10). Therefore, herein, we reported an extremely rare case of osteoblastoma of the patella in a 22-year-old young male adult.…”

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.
