ReDPAT maneuver[1]
  • Reversed Dynamic Patellar Apprehension Test
  • ReDPAT
  • Dynamic Patellar Apprehension Test (reversed technique)

Purpose

Description

  • Patient lies supine with relaxed quadriceps
  • Knee is positioned in deep flexion (~120°)
  • Examiner applies a lateral translation force to the patella
  • Knee is slowly extended
  • Positive test
    • The patient demonstrates apprehension
    • The flexion angle at apprehension is noted
  • Negative test
    • No apprehension occurs through full extension
