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

- Lateral meniscus
- Repeat above with knee varus stress and tibia internal rotation
- Images

- Interpretation: Positive Test suggests Meniscal Injury
- "Click" heard or palpated on above maneuvers
- Joint line tenderness on palpation
