A 47-yo male former semi-professional handball player presented at the emergency unit after he was injured during an official handball game. While he was about to jump off his left foot to shoot, he hit his right lateral knee, which was in a slightly bend position, against the hinges of the opponent's knee brace (Fig. 2). Clinical examination showed a non-weight bearing patient using crutches, a significant, visible and palpable effusion of the right knee. The patient's range of motion was reduced with full extension and a maximum flexion of 80° with tenderness on the lateral tibial plateau. Radiographic imaging consisted of X-ray and CT-scan to evaluate the bony structures, as well as an MRI to assess the soft tissue damage. Radiographs showed a longitudinal fracture of the lateral tibial plateau and the CT-scan revealed a Schatzker type II fracture with a 6 mm deep impaction of the articular surface on the lateral tibial plateau (Fig. 3). The MRI images reveal an abundant effusion, a bone bruise of the lateral tibia, a sprain of the anterior cruciate ligament, a non displaced bony avulsion of the posterior cruciate ligament, the fracture line and a lateral collateral ligament injury. The final diagnosis was a fracture of the lateral tibial plateau with impaction (Schatzker type II), a subtotal bony avulsion of the posterior cruciate ligament and an elongation of the lateral collateral ligament and the anterior cruciate ligament (ACL).
