"The knee series is a set of radiographs taken to investigate knee joint pathology, often in the context of trauma. It usually comprises an AP and lateral projection, although other non-standard, modified projections can be used for specific indications."
"AP view"
"demonstrates the distal femur, proximal tibia/fibula and the patella in the AP position"
"orthogonal projection to the AP, routinely done in trauma horizontal beam to better demonstrate any joint effusions"
"orthogonal view of the AP projection"
"knee AP weight-bearing view"
"view utilised to demonstrate intercondylar space, often used for OA and suspected tibial plateau fractures"
"Rosenberg's view"
"superior-inferior projection of the patella; this is an ideal projection for patients that are better suited in the supine position"
"inferior-superior projection of the patella; this projection is best suited to patients able to maintain a semi-recumbent position on the examination table"
