ABSTRACT
Positioning for the intercondylar projection showing 90-and 110-degree beam angulations to the tibia. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315382210/8ca82e7c-bd07-4171-b4f5-ebaded57b5b3/content/fig2_49a.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
The patient is either supine or seated on the X-ray table, with the affected knee flexed to approximately 60 degrees.
A suitable pad is placed under the knee to help maintain the position.
The limb is rotated to centralise the patella over the femur.
The image receptor is placed on top of the pad as close as possible to the posterior aspect of the knee and displaced towards the femur. This method often utilises an 18 cm × 24 cm CR receptor, which can fit behind the knee.
