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 patient lays prone (face-down) on an examination table and flexes their 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.
