IV. Technique

  1. Patient lies supine
    1. Knee flexed to 45 degrees
    2. Hip flexed to 45 degrees
  2. Examiner braces lower leg
    1. One hand holds ankle
    2. Other hand holds knee
  3. Medial meniscus assessment
    1. Assess for pain on palpation
      1. Palpate medial joint line with knee flexed
    2. Assess for "click" suggesting meniscus relocation
      1. Apply valgus stress to flexed knee
      2. Externally rotate tibia (toes point outward)
      3. Slowly extend the knee while still in valgus

  4. Lateral meniscus
    1. Repeat above with knee varus stress and tibia internal rotation

V. Interpretation: Positive Test suggests Meniscal Injury

  1. "Click" heard or palpated on above maneuvers
  2. Joint line tenderness on palpation
