Tibial plateau
The tibial plateau is the proximal articular surface of the tibia.
On this page:
Gross anatomy
The tibial plateau is composed of two parts:
- concave articular surfaces of the oval-shaped medial and circular-shaped lateral tibial condyles (medial and lateral tibial plateaus)
- the medial tibial plateau is larger, stronger and transmits more weight than the lateral tibial plateau
- central non-articular intercondylar area
- site of attachment of menisci and cruciate ligaments
Articulations
Via the medial and lateral menisci the tibial plateau articulates with the medial and femoral condyles to form the tibiofemoral part of the knee joint.
Radiographic features
Plain radiograph
- the tibial plateau slopes posteroinferiorly 10-15 degrees; thus anterior tibial plateau fractures may be occult on AP projections
