Osteochondritis dissecans are typically located mainly on the femoral condyle, with reported but less common cases of patella involvement. In this case report, we reported a rare case of osteochondritis dissecans located on the medial tibial plateau.
A 26-year-old Han Chinese woman presented with a lesion on her left medial tibial plateau. She was treated by arthroscopy for her knee condition. During the operation, a primary diagnosis of osteochondritis dissecans on her medial tibial plateau was indicated by an osteochondral fragment. Arthroscopic removal of the fragment was then performed. Histological examination which was done by a pathologist after the operation supported the positive pathology of osteochondritis dissecans.
The common site of osteochondritis dissecans development in the knee is on the femoral condyle, and some develop on the patella. In this case report, it was proven that osteochondritis dissecans can also take place on the tibial plateau, although it is very uncommon.
剥脱性骨软骨炎通常主要位于股骨髁，据报道累及髌骨的病例较少见。在本病例报告中，我们报告了1例罕见的位于胫骨内侧平台的剥脱性骨软骨炎。
一名26岁的汉族女性，其左胫骨内侧平台出现病变。她因膝关节疾病接受了关节镜治疗。手术过程中，一块骨软骨碎片提示初步诊断为胫骨内侧平台剥脱性骨软骨炎。随后进行了关节镜下碎片切除术。术后病理学家进行的组织学检查支持剥脱性骨软骨炎的阳性病理结果。
膝关节剥脱性骨软骨炎的常见发病部位是股骨髁，也有一些发生在髌骨。在本病例报告中，已证实剥脱性骨软骨炎也可发生在胫骨平台，尽管非常罕见。
