title: Flexion test in the coronal plane deformities of knee.
abstract: OBJECTIVE
  A little information is available in the orthopaedic literature on the clinical bedside assessment of the coronal plane deformities of the knee. We aim to explain the 'knee flexion test' to make it useful for the clinicians and the students learning the art of orthopaedics.
  
  
  RESULTS
  We describe the principle, pre-requisites, fallacy, and modification of the 'knee flexion test' along with the illustrative case description that had genu valgum deformity of the left knee of tibial origin.
  
  
  CONCLUSIONS
  The 'knee flexion test' should be a part of clinical bedside assessment of the coronal plane deformities of the knee.
