Musculoskeletal - ACL/LCL Injury
Caption
A 32-year-old male pedestrian struck by a jeep traveling at 30 mph was evaluated with POCUS for left knee injury. He sustained a left-sided rupture of ACL, LCL, and an avulsion fracture of his IT band. Pictured here is his left lateral knee US performed 10-days after the acute injury. You can appreciate the popliteus notch in the lateral femur, typically both the origin of the popliteus muscle and the plane the LCL traverses to the fibula; here only notable for diffuse edema.
