An 11-year-old boy was admitted to our hospital due to severe pain in his right knee when he landed after jumping over a vaulting box. A plain X-ray image and computed tomography scan showed an avulsion fracture of the lower pole of the patella and patella alta. Furthermore, magnetic resonance imaging (MRI) revealed an articular cartilage lesion and rupture between the inferior pole of the patella and the patella tendon. We diagnosed a sleeve fracture of the patella and performed surgical treatment. Open reduction and internal fixation were performed by the pull-out technique using transosseous no. 2 MaxBraid™ (Zimmer Biomet, Tokyo, Japan) sutures. While postoperative weight-bearing was permitted, the knee joint was immobilized in a brace for four weeks. Three months of postoperative assessment revealed excellent functional outcomes.
一名11岁男孩在跳过跳箱落地后，因右膝剧痛入院。X线平片和计算机断层扫描显示髌骨下极撕脱骨折及髌骨高位。此外，磁共振成像（MRI）显示关节软骨损伤以及髌骨下极与髌腱之间的断裂。我们诊断为髌骨袖套骨折并进行了手术治疗。采用经骨2号MaxBraid™（捷迈邦美，东京，日本）缝线的拔出技术进行切开复位内固定。虽然术后允许负重，但膝关节用支具固定四周。术后三个月的评估显示功能预后良好。
