Correct answer: AMRI to assess associated ACL and meniscal injury

A lateral tibial plateau avulsion, or Segond-type fracture, is strongly associated with ACL injury. MRI is appropriate to evaluate the cruciate ligaments, menisci and other soft-tissue structures. Plain radiographs identify the avulsion but do not define the full injury pattern.
