Acute knee pain

A teenage boy presented to the emergency department with an injury to his right knee sustained during a tackle while playing football earlier that day. His foot had been planted on the ground when he twisted, and a crack had been heard. He reported substantial pain, immediate swelling and difficulty mobilising and was unable to continue playing football. Although examination was limited because of the pain, a large palpable effusion of the knee was detected with medial and lateral joint line tenderness. Range of movement was reduced owing to the pain, and stress testing of ligaments could not be performed because of the pain and the swelling. Radiography was requested (fig 1).bmj;382/jul06_4/e075577/F1F1f1Fig 1Anteroposterior radiograph of right kneeQuestion1 What eponymous radiographic sign can be seen on the image and what diagnosis does this suggest?Answer1What eponymous radiographic sign can be seen on the image and what diagnosis does this suggest?Segond fracture suggesting…
