Abstract：
Osteoid osteomas (OOs) are non-malignant primary bone abnormalities marked by a central nidus surrounded by reactive sclerosis. They typically manifest as aggravated nocturnal pain that responds to non-steroidal anti-inflammatory drugs (NSAIDs). These growths are most frequently found within the intracortical bone and the diaphysis of elongated bones. Within the realm of uncommon conditions, intra-articular OOs (IAOOs) exhibit distinctive presentations, often leading to postponed or inaccurate diagnoses. We present a patient with OO at the distal femur, accessible through the knee joint, which was intraoperatively identified and localized using a needle pricking technique and treated by arthrotomy and mosaicplasty.
摘要：
骨样骨瘤（OO）是非恶性原发性骨异常，其特征是中央病灶被反应性硬化包围。它们通常表现为对非甾体抗炎药（NSAID）有反应的夜间疼痛加重。这些生长最常见于皮质内骨和细长骨的骨干中。在不寻常的条件范围内，关节内OO(IAOO)表现出独特的表现，通常导致诊断推迟或不准确。我们介绍了一名股骨远端OO患者，可以通过膝关节，术中使用针刺技术进行鉴定和定位，并通过关节切开术和镶嵌成形术进行治疗。
