Apley grind test

The Apley grind test or Apley test is used to evaluate individuals for problems in the meniscus of the knee. In order to perform the test, the individual lays face-down on an examination table and flexes a knee to a ninety degree angle. The examiner then places his or her own knee across the posterior aspect of the patient's thigh. The tibia is then compressed onto the knee joint while being externally rotated. If this maneuver produces pain, this constitutes a "positive Apley test" and damage to the meniscus is likely. The Apley test is named for Alan Graham Apley (1914-1996), a British orthopedic surgeon.
