Assesses for lateral collateral ligament (LCL) stability.

Performing the Test

  1. With knee relaxed at 30° of flexion, examiner places hand on medial aspect of knee and other hand grasps the lower leg
  2. Apply varus (medial to lateral) force on medial aspect of knee and the other hand pushing leg medially at the ankle
  3. Repeat with knee in full extension
  4. Positive: excessive lateral gapping and reproduction of pain
    • May have large gapping but minimal pain in complete tear as nerve fibres are completely torn with ligament
  5. If test is positive at 30°, likely LCL involvement; if positive at 0°, likely PCL/joint capsule involvement
  6. Sensitivity: 25%
