We report a case of an apparent avulsion fracture of the posteromedial margin of the medial plateau of the tibia. This was associated with a tear of the medial meniscus and rupture of the anterior cruciate ligament (ACL). This triad has been previously reported, and the plateau fracture was related to the insertion of the semimembranosus tendon. The detailed investigation of our case and some experiments on cadaver knees showed that the injury was not an avulsion fracture but was produced by varus and external rotation forces on a flexed knee. It was due to the anterior subluxation of the medial tibial plateau after rupture of the ACL.
我们报告一例胫骨内侧平台后内侧缘明显的撕脱骨折病例。该病例伴有内侧半月板撕裂和前交叉韧带(ACL)断裂。此前已有关于这三联征的报道,且平台骨折与半膜肌腱的附着有关。对我们这例病例的详细研究以及在尸体膝关节上进行的一些实验表明,该损伤并非撕脱骨折,而是由屈膝时的内翻和外旋力所致。这是由于ACL断裂后胫骨内侧平台向前半脱位引起的。
