Prepare the limb from the ankle to the groin and drape the foot which will allow free mobility of the whole limb. Place a sterile pack under the knee to maintain 30 degrees of flexion.
The patient is placed in a lateral position with all bony prominences padded. The affected top leg is extended. The bottom leg is flexed and positioned more anterior.
Place the patient prone. Prepare the limb from the ankle to the groin and drape the foot. This will allow full knee flexion.
This position can be used for operating on the top leg for a lateral approach or the bottom leg for a medial approach to the proximal tibia.
