    Abstract:
    An osteoblastoma is a benign bone tumor characterized by osteoblast proliferation that is more commonly diagnosed in young men during adolescence and youth. The condition mainly occurs in the posterior regions of the spine and sacrum, but in rare cases, the patella as well. We present a case of patellar osteoblastoma successfully managed through intralesional curettage and grafting, highlighting the need for comprehensive imaging and pathological studies to ensure an accurate diagnosis. A 26-year-old male with a history of knee plica excision presented with persistent knee pain over 1 year. Radiographic and CT evaluations revealed an osteolytic lesion in the patella, further characterized by MRI. An incisional biopsy confirmed the diagnosis of osteoblastoma. Intralesional curettage and grafting were performed. Later, subsequent follow-up demonstrated complete pain relief, restoration of knee function, and optimal graft incorporation. As shown in this case, precise diagnosis and effective management are key to improving the quality of life of patients. Furthermore, it illustrates that intralesional curettage and grafting are effective treatments for patellar osteoblastomas. Given the rarity of this condition, further research and comprehensive case studies are imperative to establish standardized guidelines for improved healthcare and patient outcomes. In summary, while the clinical characteristics of patellar osteoblastoma resemble those of osteoblastomas in general, its unique presentation warrants specific attention. Individualized consideration of adjuvant measures, graft selection, and preventive fixation is vital to ensure optimal outcomes in patellar osteoblastoma management.
