The tibial plateau (pl: plateaus/plateaux 4) is the superior surface of the tibia, consisting of medial and lateral articular facets and a central intercondylar area 5,6.

Terminology
Describing the "medial" or "lateral" tibial plateau is appropriate when used as an adjective but not as a noun, as the term "tibial plateau" refers to the singular superior surface of the tibia 5,6, the "medial tibial plateau" and "lateral tibial plateau" do not exist as defined anatomical structures. This definition also renders "tibial plateaus" anatomically incorrect unless describing more than one tibial plateau (e.g. right and left tibial plateaus).
Gross anatomy
The tibial plateau comprises medial and lateral articular facets separated by a central intercondylar area 5.
For more details, see the main article: tibia.
Radiographic features
Plain radiograph
The tibial plateau slopes posteroinferiorly 10-15 degrees; thus, anterior tibial plateau fractures may be occult on AP projections ref.
MRI
The medial tibial plateau has been described to have a slightly more concave "golf tee" appearance on saggital projections, when compared to the lateral ref.
