Driver Partially Ejected From Vehicle

ANSWER
The radiograph shows that the distal femur is medially dislocated relative to the tibial plateau. In addition, the patella is laterally dislocated. No obvious fractures are evident. 

Such injuries are typically associated with significant ligament injuries, especially of the medial collateral ligament (MCL), lateral collateral ligament (LCL), and anterior cruciate ligament (ACL). Orthopedics was consulted for reduction of the dislocation, as well as further workup (including MRI of the knee).
