Osteoid osteoma is a benign osteoblastic lesion occurring in the diaphysis of the long bones most commonly. Patellar osteoid osteoma is very rare and most commonly associated with anterior knee pain.
A 21-year-old male presenting with anterior knee pain was diagnosed to have patellar osteoid osteoma after 4 years of onset of symptoms and was treated with radiofrequency ablation. One year following the ablation patient remains pain-free and has a complete range of movements.
Atypical location of the tumor makes it difficult to diagnose resulting in delayed management. Hence, it is important to have patellar osteoid osteoma as one of the differential diagnosis in patients having chronic anterior knee pain. Radiofrequency ablation is a novel and minimally invasive procedure for the treatment of Patellar Osteoid Osteoma which can help in resolution of anterior knee pain.
骨样骨瘤是一种最常见于长骨干骺端的良性成骨细胞性病变。髌骨骨样骨瘤非常罕见，最常与膝前疼痛相关。
一名21岁男性，出现膝前疼痛，症状出现4年后被诊断为髌骨骨样骨瘤，并接受了射频消融治疗。消融术后一年，患者仍无疼痛，活动范围完全正常。
肿瘤的非典型位置使其难以诊断，导致治疗延迟。因此，对于患有慢性膝前疼痛的患者，将髌骨骨样骨瘤作为鉴别诊断之一很重要。射频消融是一种治疗髌骨骨样骨瘤的新型微创方法，有助于缓解膝前疼痛。
