(accessed on 13 Sep 2022) https://doi.org/10.53347/rID-72198 The lateral knee view is an orthogonal view of the AP view of the knee. The projection requires the patient to 'roll' onto the side of their knee, hence it is not an appropriate projection in trauma, in all suspected traumatic injuries of the knee, the horizontal beam lateral method should be utilized. On this page:This is often performed on bed-bound patients with suspected arthritis, it is an orthogonal view of the AP projection and demonstrate the joint space, yet sacrifices any assessment of fluid levels.
A true lateral projection will have the following characteristic:
The distal femoral condyles have distinct features that can be used for differentiation and hence positional errors that can be corrected. The medial condyle has a medial adductor tubercle, located superior to the medial epicondyle, a bony protuberance that acts as
the attachment point the adductor minimus and the hamstrings part of the adductor magnus.

How much flexion of the knee is recommended for a lateral projection of the patella?The patella is perpendicular to the plane of the IR. For new or unhealed patellar fractures, the knee should not be flexed more than 10 degrees (check with your medical director). Knee flexion of 20 to 30 degrees is otherwise preferred – this position relaxes the muscles and shows maximum volume of the joint cavity.
