Abstract: A method and device for positioning a patient in order to obtain x-ray views of one or both of the patient's knees comprising a generally horizontal surface for supporting the patient; a radiolucent leg support in the general shape of a triangle whereby one line segment of the triangle supports the patient's lower leg, another line segment of the triangle supports the patient's upper leg, and the vertex created by the two line segments determines the angle of flexion of the patient's knee when the patient's leg is supported by the radiolucent leg support; a means for holding a cassette in a vertical position such that a Merchant's View of the patient's knee can be obtained; a means for holding a cassette in a horizontal position such that a Bent Knee AP View of the patient's knee can be obtained; and a means for holding a cassette in a vertical position such that a Bent Knee Lateral View of the patient's knee can be obtained.
