The Beclere method intercondylar view is an additional projection of the knee, used to better examine the tibial plateau and femoral intercondylar spaces. It is anecdotally known as a 'notch view'

Patient position

patient is supine on the table with the knee flexed 40 degrees
image receptor is placed under the flexed knee slightly more superior than that of the AP projection

Technical factors

axial projection
centring point
- central ray is angled to align perpendicular to the tibia central to 1.5 cm distal of the apex of the patella
collimation
- superior to include the distal femur
- inferior to include the proximal tibia/fibula
- lateral to include the skin margin
- medial to include medial skin margin
orientation
- portrait
detector size
- 24 cm x 30 cm
exposure
- 60-70 kVp
- 7-10 mAs
SID
- 100 cm
grid
- no

Image technical evaluation

tibial plateau should be free from any superimposition
femoral condyles should be free from superimposition with the intercondylar fossa in profile, giving the appearance of a 'notch'

Practical points

ensure before carrying out x-ray the image receptor is superior enough to contain the image
