Abstract
Platforms are described for positioning a patient's knee for X-ray evaluation. The basic platform comprises upper and lower leg supports which are angled relative to each other at a fixed angle of 40 deg. The patient lies in a supine position with his leg flexed by the platform. Means are provided for positioning an X-ray film cassette generally parallel with a plane intersecting the bisecting the apex of the supports. An alternate platform provides means for tilting the platform, as well as a removable insert in the lower leg support, to facilitate X-ray examination of children and other person of short stature. The second platform also provides means for restraining the patient's lower leg to enable X-ray examination of the knee joint with the patient's quadrecepts muscles tensioned. A third platform is provided with a hinge connection between the upper and lower leg supports to enable X-ray evaluation of a knee at variable angles of flexion.
