A 17-year-old boy had persistent knee pain 1 year after medial meniscal root repair augmented with bone marrow aspirate concentrate injection. Radiographs and magnetic resonance imaging (MRI) demonstrated an intrameniscal ossicle which was not present on MRI performed before 6 months. He underwent arthroscopic excision of the meniscal ossicle. At the 7-month follow-up, he had complete relief of his pain.
It is possible that the meniscal ossicle developed because of osteoinductive cells and cytokines from the injected bone marrow or the drill hole for root repair and should be considered as a possible complication of this procedure.
一名 17 岁男孩在接受内侧半月板根修复术并注射骨髓抽吸浓缩液后，持续出现膝关节疼痛 1 年。X 线和磁共振成像（MRI）显示半月板内骨软骨瘤，而在 6 个月前进行的 MRI 检查中未见该骨软骨瘤。他接受了关节镜下半月板骨软骨瘤切除术。在 7 个月的随访时，他的疼痛完全缓解。
半月板内骨软骨瘤可能是由于注射的骨髓中的成骨诱导细胞和细胞因子，或半月板根修复的钻孔所致，应将其视为该手术的一种可能并发症。
