Knee upside down.

We present a case of a 19-year-old woman with a forced hyperextension trauma of the knee causing a posteromedial fracture, a medial meniscus root tear and rupture of the posterior cruciate ligament. The posteromedial fracture of the tibial plateau was treated operatively with open reduction and internal fixation. Anatomical reconstruction was achieved. Postoperative treatment included unlimited flexion and minimal weight bearing. After 3 months, the patient had minimal pain after weight bearing and returned to preoperative range of motion. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.
