Joint space narrowing is one of the common radiological features of OA. This is best appreciated in which of the following views (AIPG 2012)
|A||Standing films with 6 degrees of knee flexion|
|B||Non weight bearing AP view of the knee|
|C||Sunrise view that is tangential to the flexed knee|
|D||Cephalocaudal view of the knee|
Standing films with 6 degrees of knee flexion
a. Standing films with about 6 degrees of flexion at the knee show the femoral cartilage and tibial plateau cartilage in direct contact and demonstrate the joint space narrowing more reliably than non-weight bearing films.
b. Sunrise view which is tangential to the knee is best for evaluating the patello femoral articulation
