This is a test for decreased knee extension.

  • With the patient supine, the examiner flexes the knee while holding the heel.
  • The knee is allowed to extend passively and should have a definite endpoint. It should “bounce home” into extension.
  • A positive test occurs when full extension cannot be attained and a rubbery resistance is felt. Fluid in the knee joint prevents the joint from bouncing home.
  • Causes for a positive test may be a torn meniscus, loose body, intracapsular swelling, or fluid in the knee joint
