Tibial plateau & menisci

The tibial plateau from above with the medial and lateral menisci and the tibial attachments of the cruciate ligaments.

What to look at

1The medial meniscus is C-shaped with its horns far apart; the lateral meniscus is almost circular with its horns close together.
2The medial meniscus is attached to the deep MCL and capsule, so it is less mobile and torn more often; the lateral is more mobile.
3Only the outer third of each meniscus (the red zone) has a good blood supply — tears there can be repaired.
4The ACL attaches to the anterior intercondylar area and the PCL to the posterior intercondylar area, extending down the back of the tibia.

Hotspots

1Medial meniscus (C-shaped) — Wider posteriorly; the posterior horn is the commonest site of tears.
2Lateral meniscus (more circular) — Covers more of its plateau and is more mobile; discoid variants occur on this side.
3ACL tibial footprint — Anterior intercondylar area, between the anterior horns.
4PCL attachment — Posterior intercondylar area, extending onto the back of the tibia.
5Medial tibial plateau — Larger and concave.
6Lateral tibial plateau — Smaller and convex; most tibial plateau fractures involve the lateral side.
