Abstract：
BACKGROUND: Osteoid osteoma (OO) is a benign lesion characterized by an increased fibrous component in the bone marrow, presence of bone-like structures within the medullary cavity, and a surrounding sclerotic bone rim. Reports on OO located in the posterior proximal tibia are rare.
METHODS: Herein, we report the case of an 18-year-old male, admitted for the evaluation of right knee pain. The right knee pain had started 6 months prior without any apparent cause, which was notably severe at night, affecting sleep, and was exacerbated while climbing stairs or bearing weight. The patient also experienced pain on flexion. Three-dimensional computed tomography and magnetic resonance imaging revealed a nodular lesion beneath the cortical bone of the posterior medial plateau of the right tibia and an abnormal signal focus on the posterior lateral aspect of the right tibial plateau associated with extensive bone marrow edema. A small amount of fluid was present in the right knee joint capsule. The patient subsequently underwent arthroscopic excision of the OO. Postoperatively, there was significant relief of pain, and the knee range of motion returned to normal.
CONCLUSIONS: Although OO in the posterior proximal tibia is a rare occurrence, it can be effectively excised through minimally invasive arthroscopic visualization.

摘要：
背景：骨样骨瘤（OO）是一种良性病变，其特征是骨髓中的纤维成分增加，髓腔内存在骨样结构，和周围的硬化骨缘。关于位于胫骨近端后部的OO的报道很少。
方法：这里，我们报道了一个18岁男性的病例,入院评估右膝疼痛。右膝疼痛在6个月前开始，没有任何明显的原因，晚上特别严重，影响睡眠,并在爬楼梯或承重时加剧。患者还经历了屈曲疼痛。三维计算机断层扫描和磁共振成像显示，右胫骨后内侧平台的皮质骨下方有结节性病变，并且异常信号集中在右胫骨平台的后外侧，并伴有广泛的骨髓水肿。右膝关节囊中存在少量液体。患者随后接受了OO的关节镜切除。术后,疼痛明显减轻，膝盖的活动范围恢复正常.
结论：尽管胫骨近端后部的OO很少发生，它可以通过微创关节镜可视化有效地切除。
