This is a clinical test used to determine if there is a tear in the meniscus of the knee. The meniscus is a cushion of cartilage that separates the end of the thighbone (femur) from the top of the leg bone (tibia). To perform the test, the patient lays on his/her back on the exam table. The examiner holds the knee with one hand and the foot with the other hand. The knee starts bent to 90 degrees. The examiner than puts a stress on the knee by placing the “knee hand” on the outside of the knee and pressing inward, while at the same time extending the knee and turning the foot outward. If there is pain during this maneuver, it suggests a tear in the meniscus.
