A 12-year-old boy presented with a proximally retracted patella 5 months after an injury to the left knee. The clinical and radiographic features and the findings at operation led to the conclusion that the original lesion had been a distal disinsertion of the patellar ligament combined with avulsion fractures at the medial and lateral margins of the patella, produced by the medial and lateral longitudinal patellar retinacula. Loading experiments on amputation and cadaver specimens showed that these retinacula, apart from being tendons for the vastus medialis and the vastus lateralis, respectively, constitute a direct fibrous connection of considerable strength between the patella and the tibia and thus are capable of producing avulsion fractures.
一名12岁男孩在左膝受伤5个月后出现髌骨近端回缩。临床、影像学特征及手术所见得出结论，最初的损伤为髌韧带远端离断合并髌骨内、外侧缘的撕脱骨折，由髌内侧和外侧支持带所致。对截肢标本和尸体标本进行的负荷实验表明，这些支持带除了分别作为股内侧肌和股外侧肌的肌腱外，还在髌骨和胫骨之间构成了强度可观的直接纤维连接，因此能够导致撕脱骨折。
