What is the tibial plateau?

The expanded superior articular region of the proximal tibia that forms the tibial component of the knee joint.

In This Section

1. What is the tibial plateau?

The expanded superior articular region of the proximal tibia that forms the tibial component of the knee joint.

2. Which two anatomical structures form the tibial plateau?

The superior articular surfaces of the medial and lateral tibial condyles.

3. Which bone articulates with the tibial plateau?

The femur, through its medial and lateral condyles.

4. What type of cartilage covers the articular surfaces of the tibial plateau?

Hyaline articular cartilage.

5. How does the medial tibial plateau typically differ in shape from the lateral plateau?

The medial plateau is generally larger and more concave.

6. What is the typical shape of the lateral tibial plateau?

It is relatively circular and slightly concave or nearly flat.

7. Which tibial plateau typically bears a greater proportion of body weight during standing?

The medial tibial plateau.

8. Which fibrocartilaginous structure lies between the medial tibial plateau and medial femoral condyle?

The medial meniscus.

9. Which fibrocartilaginous structure lies between the lateral tibial plateau and lateral femoral condyle?

The lateral meniscus.

10. How do the menisci improve the function of the tibial plateau?

They increase articular congruence and distribute compressive loads across the knee.

11. What is the intercondylar eminence?

A raised bony region between the medial and lateral articular surfaces of the tibial plateau.

12. What are the two projections of the tibial intercondylar eminence?

The medial and lateral intercondylar tubercles.

13. What is the anterior intercondylar area of the tibia?

The nonarticular region anterior to the intercondylar eminence.

14. Which cruciate ligament attaches to the anterior intercondylar area of the tibia?

The anterior cruciate ligament.

15. Which cruciate ligament attaches to the posterior intercondylar area of the tibia?

The posterior cruciate ligament.

16. Where does the anterior horn of the medial meniscus attach to the tibia?

The anterior intercondylar area, anterior to the anterior cruciate ligament attachment.

17. Where does the posterior horn of the medial meniscus attach to the tibia?

The posterior intercondylar area, anterior to the posterior cruciate ligament attachment.

18. Which ligament connects the anterior horns of the medial and lateral menisci?

The transverse ligament of the knee.

19. Which collateral ligament attaches to the medial tibial condyle below the plateau?

The tibial collateral ligament, also called the medial collateral ligament.

20. Which joint articulates with the posterolateral aspect of the lateral tibial condyle?

The proximal tibiofibular joint.

21. What is the main function of the subchondral bone beneath the tibial plateau?

To support the articular cartilage and transmit compressive forces into the tibial metaphysis.

22. Which arteries contribute to the blood supply of the tibial plateau region?

Branches of the genicular arterial network, including the superior and inferior genicular arteries.

23. What is a tibial plateau fracture?

A fracture involving the proximal tibial articular surface of the knee.

24. Which tibial plateau is more frequently fractured?

The lateral tibial plateau.

25. What is a common mechanism of lateral tibial plateau fracture?

Axial compression combined with valgus loading of the knee.

26. What is an articular depression fracture of the tibial plateau?

A fracture in which part of the joint surface is driven downward into the underlying cancellous bone.

27. What does the Schatzker classification describe?

Six patterns of tibial plateau fractures based on their morphology and anatomical involvement.

28. What is a Schatzker type I tibial plateau fracture?

A pure split fracture of the lateral tibial plateau.

29. What is a Schatzker type II tibial plateau fracture?

A lateral tibial plateau split fracture associated with articular depression.

30. Why is restoration of the tibial plateau articular surface important after a displaced fracture?

Residual joint incongruity can alter load distribution and increase the risk of post-traumatic osteoarthritis.
